Question: Hi, has anybody used this adapter with Sigma 18-35 f/1.8 Art Lens AND Sony a6000? Did it work well? Any issue in Photo OR Video mode? THANK YOU!!
Document: I ordered this adapter hoping that it would work on my Sony A7R and indeed it does. I purchased a used Canon EF24-105mm, 1:4 L IS USM. The adapter is well made and works well. the image stabilizer and auto focuse functions work well as long as the camera is in the "AUTO" or "APERTURE" mode. In very low light conditions I found it better to use the camera's manual manual focus mode.
My Sony A7R and this lens work well at the 36 megapixel mode i.e. no vignetting. Mine is a full frame adapter.http://www.amazon.com/gp/product/B00F3ZFQK6/ref=cm_cr_rev_prod_titleI am pleased with the adapter and recommend it.
To avoid any potential light leak, I used a black ouchless hairband over the ends.Performance:I wasn't expecting great AF but it does work. I did not test IS performance, but I don't doubt that it will work fine. I purchased it just for aperture control which works perfect. I have no issues at all over the entire trip. However, I was not able to get my 85mm to f/1.2.
Purchased this to use my Canon EF lenses with my new a6000 and it works for the most part. Once I set the camera focus area to &#34;center&#34; the auto focus was slower than my Canon 5D Mark II, but more than acceptable for everything other than action scenes. I used a Sigma 12-24mm, a Canon 24-105mm EF and a Canon 70-300mm and got great shots and even some good macros. Aperture control functions well.
I used this to connect a Sigma 15-30 zoom lens to a Sony NEX-5 body. I served my purpose, but one should understand that this did not offer full functionality. If one expected full auto operation, one that would make the lens behave like a native E-mount lens, then it was a complete failure. This combination that I use consistently focuses to a point significantly in front of where a native E-mount lens would focus.For me this was no problem.
I bought this adapter after some research and for one specific purpose - to use Canon 40mm F2.8 STM pancake lens on my Sony A7R. I was not expecting much in a way of auto focus (I don't use it on A7R anyway).
Causes major vignette/cutoff on my sony A7. The mount is only cut for APS-C sensors. If you look inside the adapter you can see the inner walls block the sensor. Apart from that, the autofocus is absolutely horrendous. I didn't expect the AF to work well since its crossing platforms, but I thought it was worth noting for those interested in using AF. Finally, for what this adapter costs there is far to much play in the mount. It does not have a tight seal.
Image stabilization on the Canon lens functioned well and of course turning auto focus off and using Sony's manual focusing tool worked well as well.Satisfied at 1/3 the price of the Metabones III
PROBLEM: At first, I couldn't get this adapter to work as a full frame lens. I own a new Sony a7S Full Frame camera. I bought the Commlite adapter to use all my Canon L series EF lenses on the NEX E-mount camera body.
I have not tried any wide-angle lenses, but I think they should work better than telephoto lenses, since the rear element will be much closer to the sensor, thereby reducing the vignetting to manageable levels.I have no problems with either mount on this adapter - both the E-mount side and the EF mount side work great, fit tight without any looseness. The adapter materials appear of high quality and the exterior finish matches my Canon 40mm F2.8 perfectly.
Answer: One issue: sometimes it loose part of the conection and loose the Aperture control. You need to reconect an its ok. The same thing with metabones, so I recomend it.
