I haven't seen this lens represented here so I decided to make a new thread for it. I had the lens for a few years now (but never really used it) but I got an adapter for it today and I got quite excited to test it out so I have only one picture at the moment. Here are some specs about the lens itself:
Yashica Auto Yashidon-DX 50mm f 1.4:
Mount: M42 Only
Focal Length: 50mm
Aperture Ragen: f 1.4 to f 16, with 1 stop markings and smooth transition, no stops (at least on my copy)
Minimum Focus Distance: 60 cm, with markings in feet and meters
Weight: 304 grams, made with metal only with aluminum elements.
Lens design: 7 elements in 6 groups with 6 blades
Length: 5.6 cm
Filter Thread: 55mm
This lens is different from the Yashica Auto Yashidon-DS and DS-M 50mm f 1.4, this lens comes in 3 color combination:
1632313265449.png
   ---            

Silver barel and inner lens barel made of alumium,

   ---            

Black all-around colours,

   ---            

And black body but with silver inner lens barrel, which is the version I have:

SM-G781B    ---            

20210922_121931.jpg
SM-G781B    ---            

Not sure if my version is more common or rarer. The few times I have used it and from other people's reports, the lens seems to have a very dreamy/hazy output at f 1.4, with blooming highlights and low contrast, characteristic of a very old single coated design. The lens is not particularly sharp wide open, which one would not expect that anyways.

More samples from testing the lens yesterday morning and evening, do not trust the shutter speed count, the Lightroom plugging to edit lens info metadata doesn't work the way I wanted:

WOF00745.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 250

The lens has the dreamy soft look that single coated, f 1.4, radioactive glass elements lens design produce. It's exactly what I hoped it would be, different then the modern lens designs we have today.

WOF00745.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 250

Edited with WB correction and a healthy dose of extra contrast and dehaze, which seems to keep the dreamy look but more pleasant looking overall contrast.

WOF00746.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 1000

The lens does not have the best minimum focus distance, doesn't make get very close to the smallest of subjects but the contrast and details are still there.

WOF00746.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 1000

Edited it does bring out a bit more details in the web and the spider.

WOF00747.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 320

The lens produces huge amounts of coma in the corner (notice top left corner), which does give the background and foreground a bit of swirl effect in the right condition (but not to the level of Helios lenses).

WOF00747.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 320

Contrast can be quite easily recoverable with Contrast and Dehaze controls in Lightroom Classic.

WOF00748.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 800

At f 11 the lens is impressively average compared to more modern glass., with plenty of sharpness and contrast to go around.

WOF00748.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 800

Edited, the image looks fine, I wouldn't stop down this lens or use this lens for such usage as my Tamron FE 28-200mm f 2.8-5.6 Di III RXD can do just as well.

WOF00749.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/11.0    1/200s    ISO 640

At f 11 there's no chromatic or color aberration to speak of, which surprised me, sharp as it can be.

WOF00749.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/11.0    1/200s    ISO 640

I noticed 3 pigeons sitting high up in a tree, not giving a flying care in the world about me skulking around, so why not grab a shot of them though at 50mm there's not much of "them" in the frame.

WOF00750.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/11.0    1/200s    ISO 400

Last image at f 11, colors look fine, sharpness and details'o'plenty, nothing that would blow socks off.

WOF00750.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/11.0    1/200s    ISO 400

Even edited it doesn't look that impressive.

WOF00751.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 200

Getting subjects closer is where the dreamy effect really shines, with just a hint of swirliness in the background.

WOF00751.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 200

Dehaze and extra Contrast do cut down a bit of the dreamy feel but there's still bloom from the coma in the highlights and brightest parts of the image.

WOF00752.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 100

I do love the giant "balls" that render the horizon highlights from the vegetation in the background.

WOF00752.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 100

With more contrast control and brightening up the image, it gives it a surreal feel.

WOF00755.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 200

With larger subjects, the 60 cm minimum focus distance is easier to work with when framing the image, but at f 1.4 the DoF can be quite small, moving back and forth to catch the right focus spot for the flower.
WOF00755.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 200

This level of creamy background blur can be quite addictive.

WOF00756.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 2000

Dead vines holding the tree hostage long after they died ... or could be protecting the tree from external damage.

ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 2000

The lens tends to render a somewhat cooler tone to the images.

ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 2500

Straight out of the camera I couldn't be sure that I managed to get the right focus on the front end of the eggshell, with that dreamy look white subjects with lower contrast can be difficult to judge for their plane of focus.

WOF00757.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 2500

f 1.4 in the darkness of a forest or woodland patches can be quite helpful to get the image at lower ISO or more stable shutter speed.

WOF00759.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/2.8    1/200s    ISO 3200

At f 2 the bloom on the highlights is still there but a bit more tamed, a bit easier to judge the focus, and still get creamy foregrounds and backgrounds.

WOF00759.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/2.8    1/200s    ISO 3200

With the end of the summer, all that's left is the marks of the hectic life of the warmest months of the year, waiting to be buried under the leaves that are starting to fall.

WOF00760.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 2000

I do love the look of f 1.4 at medium distances, with a good amount of background and foreground.

WOF00760.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 2000

There is some noticeable lateral chromatic aberration, green-cyan, and redshifts between in focus and out of focus areas.

WOF00761.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 3200

Minimum focus distance again, with a medium-size leaf that caught my attention, hanging on the green vine.

WOF00761.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 3200

I was pushing the ISO a bit high, it was very very dark in the underbrush.

WOF00762.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 100

A good place to test the lateral chromatic aberration shot wide open with focus set to the green plant in the middle right above the footpath.

WOF00762.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 100

I am starting to fall in love with the look of f 1.4 even though I'm not used to 50mm FL, especially the look at medium range (2 to 5 meters).

WOF00763.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 100

This is a small garden polytunnel at my workplace.

WOF00763.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 100

This lens surprised me how much sharpness it can hold while still having the dreamy effect, while not modern lens design level of sharpness there's plenty for a print.

WOF00765.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 1000

I do love the look of f 1.4 on tunnel type of images, it really "pushes" me down the "rabbit hole".

WOF00765.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 1000

Sometimes it's difficult not to take notice of the coma levels of points of lights, like the ones in the upper part of the image through the foliage.

WOF00767.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 100

Another beautiful soft rendition at f 1.4 and medium distance, about 5 meters to the shed.

WOF00767.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 100

I did notice in this image that the dark parts do have a bit of magenta tint to them.

WOF00770.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 800

In the evening the lens started to fall apart very quickly, with a single coating and 7 elements in the design it's extremely prone to flares from any point light source... and it flares like crazy, to be executed from a lens that's 60 years old.

WOF00770.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 800

It can be used artistically but I am finding the lens pretty much useless for night shots in the cities.

WOF00772.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 640

Large flares show up in almost every image.

WOF00772.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 640

I have ordered a lens hood for the lens, a silver vented 55mm screw-in filter but it arrived this morning so I had one when I need it.

ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 1000

Even out of the frame the lens flare can and will act up in the images, being even more of a nuisance when they are incomplete and smaller.

WOF00774.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 1000

I did miss the focus a bit, it was supposed to be on the traffic light. Boosting the shadow makes the flare even more noticeable on top of the frame.

WOF00775.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 500

Flares can get quite wide when the light source is very close to the edge of the frame.

WOF00775.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 500

The highlight bloom does not seem to be noticeable at night.

WOF00776.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/5.6    1/200s    ISO 12800

At f 11 the sunstars are not that impressive, with closer lights seeming to double themselves like it's a 1970s cheap Sci-Fi movie special effects.

WOF00776.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/5.6    1/200s    ISO 12800

But there's plenty of details being resolved, zooming in I can still read the time on the clock on the roof (right top side of the image).

WOF00778.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/5.6    1/200s    ISO 10000

At f 11 the flares can get quite geometrical and colored filled as well.

WOF00778.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/5.6    1/200s    ISO 10000

I don't think I will be using this lens for night shots.

WOF00779.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 1000

I notice that the leaves in the tree right above the traffic light reflect the deep red color it was showing but when I tried to get an image of it the flare was having a party in the EVF and the image.

WOF00779.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 1000

The loss of contrast from the flare is not that big, it can easily be recovered in post.

WOF00780.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 100

I missed the focus by a hair on the shop sign, large sources of light don't seem to bother the lens much.

WOF00780.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 100

I quite like the rendition of the colors, they are very accurate and natural-looking.

WOF00781.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/5.6    1/200s    ISO 100

Turning the exposure compensation to -1 EV seems to fix the overblown highlights and I did get the focus right this time.

WOF00781.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/5.6    1/200s    ISO 100

There is a lot of detail and sharpness on the shop sign and the brick wall as well.

WOF00786.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 12800

I would not consider this lens good for astrophotography, the large amounts of coma make the point shape stars look a bit drunk, like trying to play twister at 3 AM.

WOF00786.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 12800

The church tower was quite dark with the only light source coming from a few hundred meters on the left side behind me and their own light under the tower on the right side.

WOF00768.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 12800

It's quite difficult to focus at f 1.4 and in low light at larger distances, like 50 meters away. And flare crept up on the right side without noticing it in the EVF.

WOF00768.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 12800

I always have trouble getting the White Balance right in the camera with Sony, it's just not as easy as Olympus seems to be (at least for me), and relying on Auto White Balance makes the image very orange with street lights.

WOF00782.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 100

Very beautiful and creamy background bokeh but no hint of the dreaminess that I saw that morning.

ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 100

I was very surprised to notice that pushing the shadows I got the house in the background from the literal blackness of the night back ... but I shouldn't have been surprised by the flares that were hiding in the shadows.

ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/2s    ISO 12800

I shouldn't have even tried to hope for Astro images despite the helpful f 1.4 but the coma on the edges and the high amount of blue and purple fringing on the pointy lights of the stars confirms that this lens is not good for this.

WOF00789.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/2s    ISO 12800

Trying to get the stars to be a bit sharper did not help, also the fact that I was using half a second shutter speed is not fast enough for the stars to be sharp from the rotation of the Earth.

WOF00791.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 12800

One of my fascinations and dreams of mine is moon-lite photography ... just because I don't have any common sense, to be honest.

WOF00791.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 12800

Without exposure bracketing, there's no way to get the moon exposed well enough to show the details and have the scene not drown in darkness at the same time.

WOF00792.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 4000

It's almost hopeless to try and manual focus at f 1.4 at night on a moving subject ... unless I would try to shoot at high burst and count my luck for a good sharp one.

WOF00792.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/200s    ISO 4000

I gave up trying to correct the White Balance, it was so orange that no amount of shifting around could ever fix it so I turn to Black and White.

You have certainly put the lens through its paces. I would probably not use this lens at night, but the daylight photos look pretty decent.

For focusing moving subjects, you'll probably need to use zone focus techniques. Enabling peaking may or may not help depending on personal preferences.

MF lenses like this can be a lot of fun. I have several that I enjoy when I am having fun and the success rate is not critical.

Focus peaking is wonderful but ya, MF at f1.4 on anything moving is just not a high success rate.

Thank you, I do use focus peaking with yellow colour on lowest settings to avoid false confirmations of focus and I used almost all the time Magnification as well.

PS. One of the reason I can't keep up with motion with this lens is that the focus ring, while incredibly smooth and dampened, it seems to have a torque limit of how quick and how much you can turn the focus ring (not sure if it's internal pressure or design limitation).

Sounds like dried out lubricant caking up the helicoid. The Yashinon DX has a brass helicoid in the body, held by set screws. If not torqued evenly and properly, the brass thread can distort slightly and bind. I discovered this taking apart a 50mm f/1.7.

FYI: If shooting at night with a manual f/1.4 is desired, the Minolta MD Rokkor-X 50mm f/1.4 is very good with sharpness, contrast, and flare control. More modern look to the results.

Thanks, I don't think I will try to "fix" it because last time I tried anything on this lens, wanted to rotate the M42 mount thread I ended up messing up the aperture system and the lens would not close past f 4-5.6 (give or take, the aperturing would turn but the blades would stop about 1\4 way) ... Though I noticed yesterday that, I swear, our of the blue now the aperture does close down and at the proper values too after mounting the adapter.

At the moment my plan with legacy glass is look into interesting and, if possible, unique rendition and look to the images that some vintage glass can give. As my main focus is building up on the native lenses of Sony FE since I have only one, the Tamron 28-200mm f 2.8-5. I don't mind spending 25-50 £ on an interesting vintage lens but I'm not looking to replicate something that I will probably get down the road, like f 1.4's that are sharp and blazing fast AF.
Still, thank you for the advice, it's greatly appreciated.

Last samples, for a while, as I am going to focus my interest in the Helios-44M. Though I do want, at some point, to try it for portraits as I have a feeling it would look amazing with the right light for soft, dreamy, and beautiful skin rendition. This time the shutter speed is accurate as I have to go per image and updated the lens info where I have to input manually the shutter speed and aperture, I wish LensTagger would respect the EXIF that is included in the file and just update the information that is not. As before the top image is SooC RAW converted to JPEG and Resized to 2000x2000 with only change is White Balance correction on some night shots where Sony can't correct the orange cast.

Very smooth and creamy rendition of the background even though the distance between the focal plane and the bush leaves is, about, 10 cm. This is the minimum focus distance of 60 cm.

WOF00795.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/90s    ISO 100

Pushing the contrast of the images does take out some of the dreaminess but it shows the bokeh balls at the edges with a cat's eye shape. The details on the snail are brought back to a more reasonable level with sharpening and local dehaze and clarity. I do love this image because it gives the little snail such a central stage feel, tiny in a big world vibe.

ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/125s    ISO 100

I managed to grab this shot quickly enough before the cat's attention was attracted to this stranger pointing things at her. At a medium distance, about 2 meters away, the background is quite clear even at f 1.4. Inspection up close shows there is some lateral aberration that surrounds the subject, purple in the front and cyan-green on the back. The vignetting seems to be noticeable in the top right and bottom right with a darker sky and extra dark asphalt.

ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/125s    ISO 100

I left the vignetting because it makes the center of the image more engaging, local sharpening, dehaze, clarity, and a bit of brightening up applied on the cat to bring out the orange color in her fur.

WOF00798.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/250s    ISO 160

The focus plane is on the middle section of the footpath, trying to blur the foreground and the background for a feeling of a tunnel. The coma shows up quite strongly here in the tree on the left side.

WOF00798.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/250s    ISO 160

Applying dehaze and clarity takes out most of the haziness in the image, vignetting is very noticeable here as well as I left it uncorrected.

WOF00799.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/250s    ISO 320

With the right subject and background, the bokeh can be turned into an impressionistic painting where even the stems of a flower a few cm away can be melted away at f 1.4 and minimum focus distance.

WOF00799.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/250s    ISO 320

I applied dehaze and contrast with a bit of clarity to push the contrast a bit and on the flower itself a bit of local sharpening and extra contrast to bring out a bit more separation in the petals and the stems.

WOF00800.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/250s    ISO 320

I was quite intrigued to see that the blur has a bit of swirliness to it, mostly in the foreground. The subject is about 7 cm long and the bottom end of it melted away very smoothly at the minimum focus distance of the lens. There is a tiny hint of lateral aberration with purple in the front and cyan in the background around the highlights of the bokeh balls.

WOF00800.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/250s    ISO 320

There's quite a bit of detail recovered in the wall and the stems and the contrast is just lovely pushing the file a bit.

WOF00801.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/250s    ISO 100

At a longer distance, I was surprised to see that the sharpness in the church tower bricks is very well maintained even at f 1.4. The lens seems to have a bit of variety in sharpness based on different distances from the subject.

WOF00801.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/250s    ISO 100

Some softness in the foreground from the coma is hard to correct, at least using global changes. Still wonderful retention despite the cloudy and murky morning.

ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/250s    ISO 640

With a good contrast on the plane of focus, it's quite easy and quick to get the focus right, even with or without the magnification, here it was on the white sign.

WOF00802.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/250s    ISO 640

What attracted me to this framing is the MikeyD "postage" at the "wrong address", generally the town is pretty clean but there are places where people just cheat and I noticed quite often it's the lazy teenagers who just don't care.

WOF00803.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 2000

The short (wide-angle type) lens hood does help a tiny bit with suppressing some of the more intense flares when light shines off just out of the frame, a longer lens hood would do better of course.

WOF00803.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 2000

But it's easy to get blindsided by flares hiding in the shadows (a faint half-circle colored ring on the left, next to the street lamp, another quarter-circle on the top side, and a very faint blue ball halo at the bottom of the bus stop station).

WOF00804.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/10s    ISO 5000

A bit more of a failed image on this one as I was pushing the shutter speed too low for IBIS, I have tried multiple frames and this is the best one I could get.

WOF00804.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/10s    ISO 5000

Coma at the edge around the frame has pretty much killed any sort of details, as the edges go abruptly out of shape. Though it's a bit unfair the tall order to render in close to a pitch-black area with very strong highlights, some of which could not be recovered.

WOF00805.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/30s    ISO 640

Shooting straight into a source of light, very small as well, doesn't seem to affect contrast, at least a lot better than not using the lens hood at all.

WOF00805.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/30s    ISO 640

There's a bit of flaring around the light but the coma is not interfering with the tree branches and leaves above like in the previous picture.

And yet coma rears its head again on the top right of the frame, swirling the branches a bit.

ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/30s    ISO 640

The details on the brickwork are very good after a bit of sharpening, where the subject is about 5 meters high above the ground, the lens seems to surprise me in good and bad ways equivalently and ... surprisingly (I have yet to figure out all of its patterns).

WOF00807.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/30s    ISO 6400

Shooting between slabs of brick walls and trying to keep a flood lamp on the right side (behind the shadow on the right that is one of the walls) left me with not many options to avoid the flare from the light in the corner of the building.

WOF00807.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/30s    ISO 6400

But there was a surprising amount of details and clarity left on the tree leaves right next to the light and the foothpath.

WOF00822.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 12800

Trying to shoot the church from across the street to get a flatter perspective, I was (un)pleasantly surprised that the grass was lost into a smear of muddy colors, probably because of the street lamp lights being too warm.

WOF00822-Edit.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 12800

The brickwork has lots of details though, even at this high ISO.

WOF00823.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 800

The camera preview gave me a full blown-out ceiling through the window even though I could see the pink color through the window with 2 spotlights which is what grabbed my attention.

WOF00823.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 800

The RAW file actually had the color information and even bringing down the highlights gave me a more natural pink rendition of the ceiling inside the building. The lens hood maintained a better contrast compared to not having the hood before, making it easy to bring out the details and color in the bricks.

WOF00824.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 2500

I am quite happy with the rendition of the image, unsurprisingly the sign has some purple fringing from the very high contrast.

WOF00824.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 2500

Some purple fringing was still left after using the eyedropper in the lens correction, I could have used a brush with 100% defringing to completely remove it but I wanted to see how much it can get cleaned up by using just 2 clicks.

WOF00825.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 2000

I think having more than one pinpoint light source in the frame is close to pointless in trying to frame an image because there's too much flaring to dodge, I was framing around in circles trying to find a sweet spot o minimum flaring.

WOF00825.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 2000

I was quite disappointed to notice that the clock on top of the building was lost in highlights between 1 and 4.

ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 640

Larger light sources are not causing any issues for the lens, which is good for large shops and restaurant signs.

ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 640

Some of the night shots need a bit of contrast push to get the colors more saturated unless one would prefer very dull colors.

WOF00827.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 250

I do wish I had stopped down to f 2.8 or even f 4 to get more DoF.

WOF00827.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 250

I do think the lens has a bit of barrel distortion at the center, quite easy to correct though. The focus plane was set to the corner of the building which extends about half a meter to the edge of the window and the entrance door. I am very happy how much I could recover to the shadows as I underexposed to keep the interior lights and details from going to bright, this is the kind of very high contrast situation where I find the Sony a7C doing amazingly well.

WOF00828.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 100

I thought I would give a shot (no pun intended) with the kebab shops, though it was Sunday evening so I wasn't expecting people in them, like the one above. The focus plane was set to the television.

WOF00828.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 100

A bit of perspective correction and exposure balance. I was so happy to see that the highlights did not wash out the green patterns on the wall of the shop interior, the level of sharpness is quite good.

WOF00829.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 160

I kept most of the images underexposed by -0.3 or -1 EV because of the high contrast between the shadows of the night and the bright lights of nightlife.

WOF00829.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 160

The shop owners were waiting for orders, mostly by phone or Just Eat orders.

This was a very dark scene and difficult to focus but I loved the way the entrance of the pub felt homely and welcoming with lots of laughter and chatter inside.

WOF00830-Edit.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 1250

The very high contrast of the strong lights required a bit of fiddling with a brush and -100 Defringing, I did pass the image through noise reduction because of the shadows needing boosting to balance with the strong interior lights.

WOF00831.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 12800

I thought this one would be hard to get In focus because it was very very dark, but the light reflections from inside were bouncing in the imperfection in the window glass, making even the shady Sony Focus Peaking work well despite being a high ISO image. I did slightly underexposed the image because the interior light was so strong it would blow the bottom left quarter of the window into pure white when exposing to the shadows.

It is said that there's always a door open in God's house ... how about a window open?

I do love framing "tunnel vision" pictures.

ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 8000

In post I noticed the big circles of flares right at the bottom of the frame, almost camouflaged.

Well, there was nothing black about that path so I'm not sure where did that name come from :p

ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 12800

Did take a bit of effort to frame this right, I am not used to 50mm FL, I do like the rendition of the highlights in the background, at medium distance, about 7 meters from the lamp post, is less cat's eye than going closer to minimum focus at the edges.

WOF00834.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 12800

The focus plane is on the window and the lights above it. The rendition of the lightbulbs is round-ish in the middle but just outside the center they tend to bend quite a bit when out of focus.

WOF00834.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 12800

A bit early for X-Mas lights ... but I love it, I'm an early X-Mas celebrator myself, I start whistling X-Mas songs in September, start wearing an X-Mas hat in October, and start singing carols in November ... just to piss off people :p

ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 3200

The flare seems to be a bit more tamed with the light source right above the frame and to the left side, across the street.

ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 3200

It was a bit of a challenge to try and preserve as much as I could of the orange highlight of the crossing light.

ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 2500

I was trying to shield the lens with my hand from the street lamp flare from above, which worked only for the top half of the frame (despite having the lens hood on), it's that easy to get the light to bounce inside the lens like a Ping Pong tournament.

WOF00836.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 2500

I just wanted to frame the Wellington Park sign with the dark of night behind it.

ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 2500

Same framing just without my hand above the lens.

ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 2500

The contrast is very low within the flare, which is the most intense I've seen so far in any of the flare shots.

WOF00838.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 5000

Contrast seems a bit low again from the flare of the street lamp. There's also some hallowing around the smaller LED lights on the crossing signal.

ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 5000

Most of the contrast came back when using Dehaze and Clarity, and some Defringing was required around the highlight edges. The image was pass through Topaz DeNoise AI.

ILCE-7C    Yashica Yashidon-DX 50mm f 1.4 (M42)    50mm    f/1.4    1/50s    ISO 12800

The lens is still very good in very low light, this scene was very dark but contrasty in the middle with lights hitting and bouncing off the Police car. The yellow sign is readable even before editing.

I didn't apply any noise reduction because I kind of like the more gritty look even at ISO 12.800.

A few more samples of the lens, this time only post processed files, sorry:

WOF00967.JPG
ILCE-7C    Yashica Yashidon-DX 50mm f 1.4    50mm    f/1.4    1/2000s    ISO 100

I love the rendition of this image so much, I am thinking of doing a print of it, minimum focus distance.

I love the soapy bubbles it can get in the right condition, even if they are not round.

It's very difficult to get the subject in focus if they are moving at any speed at f 1.4 but with patience and perseverance (like 500 pictures) it can make magic where the separation is just bokehlicious.

At a larger distance from the subject (or pre-focus area set) it is a bit more room to work but I still managed to not get the focus perfectly.

At distances larger then 3 meters coma can lower the level of details and clarity on smaller subjects.

Panorama of 6 images at f 5.6 very sharp and the colours are very well rendered.
