    Saw that this was available the other day. Would love to see comparisons vs the existing chinese adapters.

    Most likey, the MB will have a better coating than the Len Turbo. Most LT's have the blue dot problem (which is being fixed with a newer version) but the MB doesn't have the blue dot problem. Also, the mount maybe better than the LT. I don't know if it's worth the $200+ Price tag over the LT though. If you're looking to use it for Professional reason, then it is. But if you're just an enthusiast looking for that FF look, the LT dose a fine job.

    Well... I decided to order it?

    It was this white paper that convinced me in the end.

    http://www.metabones.com/images/metabones/Speed Booster White Paper.pdf

    Appart from FF view and extra stop, it also promises better resolution/contrast... so that is interesting. It does seem to make sense, because more information is being forced onto a smaller area. Not what people tend to experience with the Lens Turbo though?

    Anyway, I hope that turns out to be true. Will post samples when it arives.

    I suppose if you didnt already have a camera, buying the A7 is almost the same money as a Nex 6 plus a speed booster.

    But if you mount an MD Rokkor 50mm f1.4 on the A7 it will behave like a f1.4 lens. On the metabones speed booster it will become a 50mm f1.0, which will be kinda crazy.

    Well I have the lens turbo for fd and it really isn't sharp wide open. I've been using it on a 55 1.2

    If the metabones is that much better I may try it.

    If you read the white paper I linked to, on page 20 they show a comparison shot with a 50mm f1.4 Carl Zeiss lens on Yashica/Contax mount.

    The comparison photos are shot wide open, and it actually shows an increase in sharpness with the Speed Booster. To be taken with a grain of salt (it is marketing material after all) but looks promising

    The Metabones Speedbooster works. I use the C/Y speedbooster on my NEX 7 with some very nice results. I have posted this before but here is my speedbooster folder on flickr.

    The difference between the Metabones product and all the rest is one of design, investment and commitment. Metabones actually hired Brian Caldwell, a noted lens engineer, to help perfect the already existing idea of the focal reducer (which has been around forever) and apply it to a quality device for the new crop of mirrorless cameras. All of the other companies products were just 'me to' products that quickly copied the very clever idea that Metabones was able to bring to market. Metabones spent time, money and effort in creating a product that delivered on its promises. Every single other focal reducer made after that was simply a hastily thrown together play on the concept with no concern for quality testing or image quality but rather simply to make money on somebody else's idea. The blue dot problem is proof positive of this. Nobody 'engineered' the lens turbo. They just threw some cheap coke bottle glass together in a close approximation of the real Mckoy on dropped it on the market at a discounted price. Result? Less then stellar performance and blue dots.

    Remember, a focal reducer is just another lens you are putting on your camera. And like all other new lens products you get what you pay for. If you are going to go thru all the trouble to use a really good quality legacy lense then dont jam a crappily made piece of inferior glass between it and the sensor. I was nervous using the speedbooster the first time but as far as Im concerned it has delivered on its promises.

    On a side note, I used to shoot Minolta glass almost exclusively on my NEX. But I went with the C/Y version since I also have a love of old Yashica ML lenses. I am very interested in the MD speedbooster but it is unfortunately not in the budget right now. I would be interested to see anything you are able to capture using it.

    Your metabones shots are beautiful, just stunning. I assume many of those were shot wide open, but don't seem to suffer for it. Thanks!

    I think it's hard to justify the price of metabones unless you have a lot of glass on that particular mount. My collection has grown to dinner-party-embarrassment levels. I hope my 50mm Rokkors produce Bokeh as good as your 50mm Yashicas. Also excited to use my 24mm Rokkor as an actual wide angle.

    Hahaha Jim... I'm very happy in m43 land with a Speed booster... but recently I have become bitten by the Zeiss monster and to get to an effective 28'ish I would have to look at the 21mm Distagon... which is prohibitively expensive. The total for a 28mm Distagon, Nex 5n, evf, and a speed booster is cheaper! So I peek over here from time to time - I'm very interested in seeing how Metabones performs on the nex. I have no doubts on the m43 platform. I'm sold there.

    Thanks jai. Most of them were indeed wide open. And I forgot to mention not all the shots were from C/Y lenses, some were from M42's using an M42/CY adapter and some were from Tamron Adaptall lenses, which can be used with a C/Y adaptall mount. Glad you liked the photos. :)

    Testing

    I have been testing out the metabones MD to nex, and after a while wondering why my shots were looking crap i eventually figured out I wasn't able to achieve manual focus.

    I was about to write a strongly worded letter to metabones, but then i figured out it was adjustable.

    http://www.metabones.com/smart-adapter-operation-manual/155-infinity-adjustment-speed-booster-only

    With my 24mm F2.8 lens at F8, this is what i originally got with focus set to infinity:

    After a fair bit of tweaking, i managed to get it looking pretty good i think.

    Pretty dodgy that it was this far off though? It wasn't just with that lens, but with everything i tested

    The 50mm MD Rokkor F1.7 i have is basically unusable, because I can't stop it down?

    The depth of field preview lever on the back on the lens is catching on the adapter somehow. Luckily I don't have the same problem with the 50mm MD F1.5, or any of my other lenses.

    The adapter is pretty heavy, so when combined with the 50mm F1.4 it has a substantial heft.

    A bit of an update in case anybody is interested.

    The metabones speedbooster for MD glass is far from perfect. I have had to cut the depth of field preview tab off quite a few of my lenses now to get them to stop down. Pretty disappointing considering how much I paid for the adapter.

    And it is super heavy. And most photos I take with it have very noticeable vignette.

    I should have really sent the thing back! But I didn’t, because I kinda love it.

    The images that I take with it just pop, in a way they never did with a dumb adapter. The extra contrast is really noticeable. The vignette often looks nice. And it is really nice to get the field of view Minolta intended, especially with my 24mm f2.8.

    Bottom line is, I haven’t used any of my MD glass without it since I got it 2 months ago.

    I guess it is probably a lot less relevant now, as you could probably get an A7 for the price of a nex 6 with a metabones adapter.

    Question to Jai:

    Did you ever try at very small pertures like F11 or F16 in highly reflective scenes like white wall with dark subject or with the sun at a close angle to the lens to see if you get the purple center blur ? I have a Zhongyi and this effect is the only defect that i found to these

    No, that is one definite advantage of the Metabones. I have never seen this issue in any of my shots.
