Title sums it up pretty well. My mc-11 came in today and while this nicely priced adapter looked really promising, I know a lot of people had many unanswered questions.
I bought this adapter to use on my FS7. I have 3 sigma lenses (35 A, 50 A, 150-600 C) and a bunch of Canon lenses everything from the nifty fifty to L series lenses.
The Sigma lenses seem to communicate fine. Aperture control and focus distance readouts work as expected. I read that autofocus for video would not work. When pressing autofocus button the fs7, the lenses simply searches for focus but it never finds it. When the fs7 is switched to autofocus, focus seems to lock on slowly but eventually gets there. I cant really compare properly since i never used the fs7 with a proper emount lens. Perhaps it works like it's supposed too but Either way autofocus on the fs7 with the mc-11 is not worth it.
The other part of the adapter I was excited about was the distortion correction. Again, this was hard to test. I navigated to the menu to turn it on, however, all I saw was "off" or "auto" when set to auto, the camera turns off the preview LUT. As far as distortion correction, I can only assume its working without testing it properly against a brick wall. The sigma art lenses have very little distortion to begin with anyway, I'd really want it for a lens like my Tokina 11-16.
Now the question everyone is wondering, does the adapter work with Canon lenses? In short no at least not with the ones I tested (50 1.8, 24 1.4 and 24-70 2.8 I) while you can mount these lenses, the aperture control is not compatible. The 50 would switch between f2 and 2.2, the 24-70 wouldn't change aperture at all and the 24 1.4 would close down fine but when opening up it would flash to wide open before it went to the next apeture value. I could test other lenses but thought it was pointless. Perhaps Sigma will add support for Canon lenses in the future.
The adapter is still on pre-order at most retailers so it seems I'm lucky to be one of the early recipients. I plan on returning the adapter so if anyone has any questions let me know and I can try to test it before I send it back.
Update: I tested it with a few more lenses. Tokina 11-16 II, Canon 100mm Macro 2.8 (Non-l), Canon 135 f2, Canon 40mm 2.8 Pancake. The only lens that I was able to adjust the aperture with was the 40mm Pancake, however, it did the same thing as the 24 1.4 where (when opening up the aperture) it would quickly open up all the way before moving to the next aperture value. This would be fine for certain types of shoots but wouldn't work for documentary or event style projects.
