It is recommended to have a look at this article first to get an idea how this brightness graph works. Nikon's AF-S 50mm f/1.4G on an FTZ adapter is sharper in the corners at f/1.4 than this lens as shot on a Z camera, and autofocuses and handles so much better. Adapted lenses are kludgy at best, and the autofocus LEICA to Z adapter is more of a science experiment than anything for practical, serious shooting. The TTartisan 50mm f/1.2 exhibits some barrel distortion a close distances. Nothing heavy, but it is there. I didn’t feel the need to correct it in post, but it can easily be done since it’s very minute, so the need to crop while correcting is a non issue. Conclusion and Sample Gallery So in the end this is not a lens that will yield great bokeh in any situation (like e.g. the Sony FE 85mm 1.4 GM), but in many situations it yields appealing results nevertheless.
The Samyang 45mm 1.8 is the lightest lens on this list even though it is noticeably bigger than this TTArtisan lens. It shares the issues with corner sharpness at infinity but not with flare resistance and Coma. Instead the loCA correction is noticeably worse and the bokeh plagued by strong onion rings. If you're not getting ultra-sharp pictures with this, be sure not to shoot at f/11 or smaller where all lenses are softer due to diffraction, always shoot at ISO 160 or below because cameras become softer at ISO 200 and above, be sure everything is in perfect focus, set your camera's sharpening as you want it and be sure nothing is moving, either camera or subject. If you want to ensure a soft image with any lens, shoot at f/16 or smaller at ISO 1,600 or above at default sharpening in daylight of subjects at differing distances in the same image. So in summary, I really like this Chinese lens and I think it opens the doors to ultra-fast lenses for many more people. I was pleasantly surprised and I’d be using it more day to day if I wasn’t always testing different lenses for YouTube!I think the lens has a nice retro-look to it and looks a bit out-of-place on the X-H1 but would like fabulous on an X-T* or X-Pro series. Compared to the expensive plastic rubbish offshored to China by Nikon and Sony, this is a gem of domestic Chinese precision at a bargain price. This lens is like a breath of fresh air after reviewing countless high-priced throwaway plastic lenses from the big names. This lens should last at least a lifetime; there's nothing to break or go obsolete. Utility Plate, 9:43 AM, 19 December 2020.

This is Sony’s idea of a modern compact 50mm lens. The optical qualities are generally better (especially flare resistance and Coma correction), you get AF and very nice build quality. The price is a bit staggering considering the specifications though, but sometimes you can find this lens heavily discounted which makes it more attractive. The TTartisan 50mm f/1.2 is an instant recommendation for anyone who likes to use the 50mm focal length on an APSC camera. This is a shot up into the skies. Some vignetting at f1.2, less at f1.4, and it’s mostly reduced by f2. By f2.8 it’s gone. A very cool thing is that this amazing build quality from the M-mount lens line has been carried across to this 50mm f/1.2 lens. It really is built to a very high standard. There are many nice 50mm lenses out there, with which one could compare this lens to, but they would mostly be full frame lenses for other systems that would have to be adapted, for example Leica 50mm f/1.4 Summilux, Voigtländer Nokton 50/1.5, 50/1.2 or 50/1.1. TTartisan even has their own 50mm f/0.95, and 50mm f/1.4 for M mount, and 7artisans made the 50mm f/1.1 as well as the Kamlan 50mm f/1.1 – So there are PLENTY of options for fast fifty lenses in a lot of different price ranges.As is often the case when using lenses with strong vignetting on the later Sony sensors there is a slight buish teint in the corners visible. This is more pronounced at wider apertures and it is rarely noticeable in real pictures, but you might still be able to spot it in one or two of the sample pictures. Sharpness infinity (42mp Sony A7rII) In the SLR era every manufacturer had at least one fast compact 50mm lens on offer. Compared to fancy modern lenses the flare resistance is usually worse as is corner sharpness at wider apertures. Many of these perform quite similar when comparing to the TTArtisan lens being reviewed here though. Most of the cheaper lenses like the Brightin Star 50mm f1.4 and Pergear 50mm f1.8 are not as fast and still don’t perform this well, but I would say they have a bit more character, better micro-contrast, more interesting flaring. The mechanical quality generally feels good although I do see some cost cutting measures, as the markings are only printed, not engraved and filled with paint as I am used to from TTArtisan. There is a little bit of vignetting wide open, but not too much. I would say about 1/3 exposure stop. It goes away at f/2. It is to be expected, so no surprises there.
If you want autofocus on Nikon Z, the Megadap MTZ11 autofocusing adapter has its own built-in autofocus motor. Bravo! Indeed this 50mm 2.0 is a bit softer due to undercorrected spherical aberration, stopping down to f/2.8 improves the situation significantly. Flare resistance Sony A7III | TTArtisan 50mm 2.0 | f/2.0 For comparison’s sake I included the Voigtlander 50mm 1.2 here. I consider this performance average for a lens with these parameters. You can clearly see some onion ring structures caused by the use of aspherical elements though. We will be looking at 100% crops from the 24mp Sony A7III and the Leica M10. Both cameras do not have an anti aliasing filter in front of the sensor.Fortunately I could use the lens cap from my Canon EF-M 18-55mm lens, which has the same 52mm filter thread and which I don't use anymore. The 50mm 0.95 TTArtisan lens is big chunk of metal and glass so for me it is less suited to compact Leica M cameras. Yes it is possible to use this combination but the lens balances far better on the Leica SL cameras ( Leica SL, Leica SL2, Leica SL2-S).The larger grip of the Leica SL also makes it a more comfortable setup to use. As the Leica SL is a mirrorless camera you also get perfect focus every time and you can skip the lens calibration process. TTArtisan 50mm f0.95 + Leica M240 Leica M mount TTArtisan 50mm f0.95 The optical-, as well as the build quality of the lenses from both companies are amazing. It’s getting better and better. 7artisans makes incredibly well built lenses, of which I currently own the M-mount 75mm f/1.25 as well as the new X-mount 35mm f/0.95 (review here). For portraiture it isn’t so important how flat the field is, it is more interesting to see what the sharpness is like when focused at different parts of the frame to take field curvature out of the equation. positions of crops in the frame
