SigmaMC-11 Canon EF-E Lens Mount Converter, Black

The price is on par with other adaptors... it's still very expensive for what it is... It's some plastic and bits of electronics.But boy does it perform well for me.I have a Sony a6400 and a Sigma 18-35mm f/1.8 Art lens (Canon mount).It does the bridge perfectly. All (as far as I can tell) Sony native features work with the Sigma lens! Eye AF, Focus Peaking. It's really great. It's not very fast with the 18-35 but enough for my needs.I also use it with a Canon 50mm f/1.8 STM and it works great for stills. It does Eye AF/Face tracking which is my main concern. It doesn't do AF in video however.Overall very happy because I have a perfect platform for my Sigma 18-35 f/1.8 Art lens.

I haven't really tried for videos, just once or twice, and the AF for my Canon lenses didn't seem to be working well or at all.However, when shooting stills with the A7iii (latest firmware v3) and latest firmware of the MC-11 installed (1.24), this works very well indeed for all my Canon lenses (EF 40mm f2.8 STM, EF 50mm f1.8 STM, EF 85mm f1.8, EF 100mm f2), and very likely on many others.AF-S and AF-C very responsive, including face detection and eye-AF. Obviously, in terms of smoothness of the AF and motor noise there's really no comparison to a native lens, but I'm more than happy with the purchase.

I have the canon 24-105, 35 f2.0 IS and the 85mm all of them works with autofocus in photo mode. tracking works and eye detection. it doesn't track quickly when a target is moving towards you, far from original lens. it does follow and it does it quicker then my old canon 5d mkii. you can use the slowest setting for burst shooting when target is moving then it keeps up. in general the focus is quick. I haven't looked in to the percentage of how many that is good. I have a feeling that it is very high. I don't have many unsharp photos. all in all it is much better focusing then my 5d mkii.For video the lenses doesn't work so well with the features Sony cameras have . there is no autofocus but the IS works very well. and you can use focus peaking or the magnifyer.

first of all this is a quality convertor by sigma the autofocus works better outside with better light using a Canon 17 40 f4.0 L on a Sony A7 it does hunt a little bit but I mainly do landscapes so shoot manual every thing else eg Aperture and modes work excellent, on the whole I have no regrets buying this convertor

Just Buy It ! You Wont Be Dissapointed.I have a Sony A6000 (as well as my Sony A7Rii) and after 2 years of trying to find a decent zoom lens for my A6000 - I tried all the Sony versions, which were poor quality and over-priced, however, this little device has finally ended my quest!I am using this with the Sigma 17-70mm (which equates to 25.5-105mm - a brilliant every-day zoom range) which now gives me a relatively fast zoom - F2.8-4. and the optical quality is better than the Sony Zooms - very sharp and virtually no chromatic aberrations or vignetting - and it cost just £319 brand new with 3 year UK warranty - simply amazing!However, it's not perfect. Things to be aware of:- It's nicely compact but quite heavy- The auto-focus is not as fast as native Sony lenses - but fast enough for kids and pets etc.- You will need to persevere to get the auto-focus working properly i.e. test out the different settings. It took me a couple of hours, but now it's great.- Auto-focus is not silent, so you might hear it in videos - not ideal.- It works even better on my A7Rii but I need a much higher quality lens for this little beast

I bought this to use my Canon L lenses with my Sony A7s2If manual focus is you're thing, then this adapter works fine, allows you to change aperture and IS works too !However, none of my lenses would autofocus, they were just hunting consistently.I used this with:24-105 f/4 IS L16-35 f/4 IS L400 f/5.6 L85 f/1.8 USM50 f/1.8 STMAutofocus was poor on all of the above, however simply mounting did work fine.

Bought this to use my Canon L series lenses on my new Sony A7iii. Happy to say for photography the lens have all given reliable focus in good lighting conditions. In lower light all my lenses hunt and struggle to focus. I can live with this until I get funds to purchase Sony lenses over time. Different story for video, cant use autofocus at all.My lenses are 17-40 F4L, 28-105 F4L, 70-200 F4L. Overall pleased with this adaptor as its letting me use the Sony with my Canon glass for photos and eye tracking works very well. Dont expect 100% accuracy though and it does drop considerably in lower light, and for me forget autofocus in video. (video may be better with a faster lens)

It works and delivers.It is not fast as a native lens, but it is expected.I am using this adapter on Sony A7RII with various lens and always single shot, AF-S with small central point focusSo far:Canon EF 16-35 F4 L IS - works good. low light - difficult focus. For some reason the IBIS in A7RII needs to be set manual in order to work...Canon EF 24-70 F/2.8 L II - works fast. reliable. Low light expect some slow focusing sometimesCanon EF-70-200 F/4 L IS - works. Not very good focus and hunting around the long end of the lens (135++) Low light - not reliable muchSigma 35mm ART - works as expected - hunts focus sometimes in low light.So in conclusion - it is not th ebest solution, but for this money it deliver and you can use your canon lens with SONY A series.

I was very happy with the output of this converter. More importantly it works great for video unlike the metabones converter which only works well and for photos

ótimo produto

He estado utilizando el convertidor desde que llegó a la fecha y funciona muy bien con el 50 mm Canon EF. Mi cámara es una Sony a6600, la rapidez de enfoque es bueno, las imágenes las toma muy nítidas.Buen desempeño.

Very good mount converter of EF mount Selected Sigma lenses on a Sony E mount camera for Photo & Video both. It also supports EF mount Canon Full Frame lenses for photo only but not in video. Also Canon EF mount Crop lenses are not supported for still & Video. Only draw back is it is not weather shield.

Funziona perfettamente con le ottiche Sigma attacco Canon; veloce e preciso. Come se non ci fosse!
