    Loxia 50mm f/2 Planar vs. Zeiss 55mm f/1.8 Sonnar vs. Sigma 50mm f/1.4 Art http://ilovehatephoto.com/2015/03/3...5mm-f1-8-vs-loxia-50mm-f2-vs-sigma-50mm-f1-4/

    loxia 50mm f2 build quality.
    Here's some attention to detail. Instead of having a plastic notch to lock the twist-on lens hood in place, they have a steel ball bearing! I feel like a peasant for never having seen this kind of design before.

    loxia 50 build quality.
    Blue weather sealing gasket. Nice touch.

    Lens extends a tiny bit at the minimum focusing distance. The end of the lens doesn't turn. CPLs are okay.

    Here are some sample photos at Disneyland California Adventures:

    Great review and I can wholeheartedly agree - all are stunning lenses.

    The photo samples are beautiful too; in particular for me, your model portraits on the beach :)

    I personally prefer the rendering of the Sonnar to the Sigma without doubt in the context of fine art / portraiture. It's a mini Otus for sure.
    For me, the Loxia has a very different rendering to the other two - it's more cinematic/reportage friendly IMHO.
    I can see a case for actually owning both lenses. One for street shooting and the other for studio, portraiture etc... They just render so differently.

    Interestingly the transmission values of these lenses (at least the Sonnar and Sigma Art 50 are closer than their F-stop would suggest).
    The Sonnar F1.8 has a Transmission value of 1.8. The Sigma Art 50 F1.4 has a transmission value of T1.7
    http://www.dxomark.com/Reviews/Sigm...-DG-HSM-A-Canon-versus-Carl-Zeiss-Otus-1.4-55


    I find it interesting that the 55mm has more 'pop' than the other two though. It's been noted by some in the FE55 thread that they find the transition from in focus to out of focus too fast. Personally I love this, but I know from Ad and a few others on the FE55 that they do not like this behaviour. For me, it reminds me of the behaviour from good medium format glass in that the transition is very quick but linear across the frame.
    You would be a lot more knowledgable than I would though - do you think that perhaps the Sonnar 55 pop is a result of having a flatter plane of focus than the other two lenses, or is it a case that the additional 5mm translates into a quicker drop off to out of focus relative to say the Sigma Art 50 1.4?? Certainly I've tried my own FD55 1.2 and the Sonnar 1.8 and still do not get the same 'pop' from the FD55. Perhaps it's a part of the Sonnar design?

    Finally a small request/suggestion for future reviews - Please could you enable optical corrections/lens profile corrections :) . Lens corrections are as much a part of the lens design as the glass elements themselves. Disabling the corrections only tells a part of the lens performance story as mirrorless lenses are designed with both physical and software corrections in mind. I see it as akin to turning off traction control on a Porsche and determining that it's handling is very unpredictable.

    Thanks for your time and all the hard work on your review. :)

    Thank you for your comments again Tom! It always feels good to have peers read our work and enjoy our writing.

    The Sonnar 55 pop is a mystery to us, and honestly, we've been trying to get to the bottom of its magical pop. I used to be a Canon and a Pentax shooter, and I've shot all the nice L glass and the f/1.2s, and they can't compare to this Sonnar. We definitely think it is the fast transition between the focused and unfocused areas of the image. Leica summicrons and summiluxes have very similar effects.

    There was this website that did an extensive review of something like 20+ lenses adapted to a Sony A7R. You could download a zip file containing all of the images. If I find the URL again, I will post it here, but I urge you to do some blind testing of your own. What we did, was we downloaded the photos, and just inspected them randomly for their bokeh. We always manage to pick out the Leica and the Sonnar images as the best with the most pop.

    As for the flatter plane of focus, I think this is a distinct possibility, one that we have also thought about before. However, the Loxia 50mm Planar also has a very flat plane of focus yet it didn't offer as much POP as the sonnar. We think it has something to do with the combination of a flat field of focus + the bokeh + the micro-contrast. Take a look at that technical Leica article within our review. It is very informative.

    Sure, we'll remember to do correct/un-corrected tests in the future. And you are right, I leave corrections "on" 100% of the time anyways. We used the uncorrected data this time to be fair to the Sigma because it isn't a native E-mount lens.

    I'm a big fan of the Loxia 50mm. It's my usual "walking around" lens now.

    Zeiss magic. Look at the pop in the first photo!

    Great lens, but no magic. The 50mm has some pop, but that picture is about my seeing the light coming in through the plastic overhead, lighting the face against a dark background.

    My camera bag isn't big enough for Canon gear.
