I wish Sigma had manufactured the brilliant Adaptor years ago when Sony first brought out the E Mount CSC Cameras it works really well with my Sigma 150-600mm C Lens. It Autofocuses like the Lens was connected directly to the Camera, knowing also that there are many other compatible lenses that work with the Adaptor too is a real bonus.

Using on A7R2 camera. Have Sony's 35f1.4, 85f1.4, 16-35. Have also used Sony's 70-200f4 and Sony's 100-400, but find no need to purchase these given how nice Canon's 70-200f4 and Canon's 400f5.6 work with Sigma MC-11. The Canon's 70-200 becomes stabilized, works great down to 1/20 sec @ 200 mm. These are shutter speeds, that were newer an option on the original Canon bodies that i had before. Tracking speed, precisio. And object recognisition and following is excellent. Well above Canon's xxxD level of cameras and in line with 5d m4. This is far beyond what i was expecting from adapted glass. Focus precision is exceptional and keeper rate due to focus precision and addition of in camera stabilization exceeds that of my previous 5d Canon which was already very close to 100%. Some caveats, which are more of a wish list - farr edge focus points are less active at 200mm, but this might be Sony's focusing algorithms which at these focal lengths are giving more priority to center of the frame, which is the preferred approach in most cases anyways. The 400 f5.6 appears to be slightly slower than on the canon 5d body when focusing close to minimum focus distance, at longer focusing distances the performance difference, if at all, is negligible. The lens also becomes image stabilized (which in Canons stables would cost me a thousand more) and can be hand held down to approhimately 1/120. The gain from in body image stabilization is less dramatic than for the 70-200f4, but still 2 stops for 400mm lenss of additional headroom. For action 1/120 anyway is borderline slow in most cases. Also, edge focus points appear no to get much of priority, but subject tracing is very good at 400mm and focus precision without any focus calibration (newer liked it much on Canon) is excellent. The adapted Canon's 70-200 f4 is indistinguishable from Sony's f4 zoom whit exception that eye focus and flexible focus are modes are inactive. Eye focus needs to be done the old Canon's way - with a precise focusing on eyes of the subject and this actually is not a downgrade when compared to the Canon in viewfinder mode. Firmware version for MC-11 is 1.11. When moving to Sony, was not expexting to have such a positive experience, including with the adapted glass. In conclusion - exceeds all expectations; the adapted lenses work very much the same as on 5d Canon (real surprise to me) just with added benefit from in camera stabilization. P.s. Canons 85f1.8 works also good, but this will be sold, as at 85mm focal range i can not live any more without eye focus (don't undervalue the convenience of this) and thus i have already bought 85f1.4 Sony.Vollständige Rezension lesen

Works fine but there some flaws 1. Work differently with different lenses and A7 series bodys. AF accuracy and functions (such as face recognition, Eye-track) are not supported by different cameras or different lenses. 2. AF only works in AF-S mode, AF-C does not work, at least with sigma ART lenses. 3. Wide angle lenses suffer from image quality degradation in the corners of the picture. That may not be visible in daylight photography. But it is very annoying in night photography. The corners get distorted and the stars look bad in the corners of the picture. Also this happen with many other adapters including commlite.. 4. The adapter automatically adds lens correction profiles on Sigma ART lenses. The profiles can not be turned off even in RAW files. Some times the lens profile is good thing, but some times its better without it yet using this adapter you can not turned it off it is applied always automatically. Although the price of adapters are pretty high (metabones for example..) they do not provide the best quality and does not make a third party lenses work in a 100% the way they work with other cameras. If you are looking to adapt wide angle lenses, I would suggest to look for native Sony E lenses instead. Also rent it somewhere and try it for yourselves because it may not provide enough quality for your needs it certainly did not for mine.. I still use this product, but I had to get used to the fact, that the lenses I used on my Canon camera work differently on my Sony A7 using this adapter. Camera Sony A7 II, lenses sigma art 24mm 1.4f, samyang 14mm 2.8f, sigma 85mm 1.4f ART all canon mounts. I added the picture made with sigma 24mm 1.4f ART lens. As you can see the stars are streched towards the corners. Every corner of the picture is effected this way, the further from the center the worse, the effect appears in a big area nearly ~30% of the whole picture. Disappointing indeed. And this is 24mm, 14mm looks even worse... On a day shots it is barely visible, sometimes you will notice it in the bokeh highlights in the far corners of the picture, like the second photo I added., they look streched like the starsVollständige Rezension lesen

Bought this converter to be able to use my Sigma 20mm Canon E fit lens on my Sony A7 and I have to say it works flawlessly and it also works with a few of my other Canon L lens.
