Sigma Mount Converter MC-11 For Use With Canon SGV Lenses for Sony E

On the a6300, having used the Metabones and Commlite adapters, this thing is far, far better. While it only officially supports Sigma EF mount lenses, I have found that a number of Canon lenses work as well (however, you will only have AF-S and AF-C modes). For example, the Canon 50mm 1.4 USM, which doesnt work at all on the Metabones or Commlite, works on the MC-11 quite well. You can even get a degree of focus tracking by setting your shot priority to AF and choosing AF-C (Wide seems to work best). No, its not what youd get from a Sony native lens, but its quite usable. My Canon 70-300mm IS USM takes comparable images, and performs almost as well in AF as the Sony G 70-300mm. Certainly there are reasons to buy the Sony, but for most, this would an effective bridge. On supported lenses like the Sigma 150-600mm Contemporary, I have to say its almost like using a native lens. I say almost because under normal shooting conditions I wouldnt be able to tell the difference; some native lenses perform far worse, some better. I have tested the adapter with these non-Sigma lenses (assuming AF-S or AF-C mode) - Canon 24mm IS USM - Works Canon 40mm STM - Works Canon 50mm 1.4 USM - Works Canon 18-135 IS USM - Does Not Work Properly Canon 70-300mm IS USM - Works Canon 75-300mm IS USM - Does Not Work Properly Sigma 150-600mm Cont - Feels like a native lens. Quick update - I shot a lot of pics at the Indy 500 this weekend using the a6300 and the Sigma 150-600mm Cont. The combination performed quite well, but you really have to know your AF modes to get the best performance. The only negative I can think of is that it doesnt support EF-S lenses, which is a shame and the only reason I have to hang onto my Commlite adapter.

fantastic solution if You have canon AF lenses and want to use them with Sony A7II and III. I happened to own/use Canon 5D mark IV with Sony A7II and III Full Frame bodies. As far as Canon glass I own 24-70mm F2.8 II L, 70-200mm f2.8 IS L, 50mm f1.8 STM, 85mm f1.8, 100mm f2.8 L macro and all of them work pretty much like native Sony glass would as i own bunch of Sony/Zeiss native ones so i could compare. Dont even hesitate, get it and use Your Canon glass without limitations.

This works as described. I have a Sony A6500 and I have previously purchased a Fotodiox adapter, and that only worked on one of my lenses. After I returned that one I was deciding between the Sigma MC11 and Metabones. At $150 cheaper I decided to give Sigma a try first. The Sigma MC11 work for all my Canon branded lenses, including: EF85/1.8 EF35/1.4 EF70-200/4 EF24-70/2.8 and they all focuses very fast in both AF-S and AF-C modes. However, it doesnt work with my old Tamron 17-35/2.8-4 and nor does it work well with my old NEX5N, which did focus with Canon lens but very very slowly. Update 2017 Aug 17: Recently I have been using the adapter on my EF85/1.8 for some indoor sports on very dim venue. Probably one of the toughest condition for AF systems. (typical setting is f/2, 1/500, ISO8000) and the focusing speed and accuracy was excellent. I have not had a new Canon body for 10 yrs (had a 1Dmk3 before) and I now appreciate the advancement in AF technology in the past 10 yrs.

Works Great! Auto focus works on both a Sony NEX-7 and a Sony a6300 with all of my Canon lens: Tamron Di II SP 17-50mm F/2.8 Tamron Di SP 70-300mm F/4-5.6 Tamron Di II SP 60mm F/2 MACRO Canon EF 50mm F/1.8 Kenko C-AF 2X TELEPLUS PRO 300 converter on the 70-300 (making a 140-600mm, used manual focus at the 600mm end). I HIGHLY RECOMMEND TRY THIS ADAPTER !!!

I have tested the adapter with these non-Sigma lenses Camera body used: A7M3 (ILCE-7M3) lens: Canon EF 35mm f / 1.4L USM, 2012: Works Canon EF 50mm f / 1.2L USM, 2012: Works Canon EF 16-35mm f / 2.8L II USM, 2010: Works Canon EF 70-200 f / 2.8L USM, 2005: Works Only have AF-S and AF-C modes, AF performance is slightly lower than when using a Canon body, and I do not know if its a Sony body or a converter problem. Because I do not have a Sony native lens. Tested indoors late at night and taken at maximum aperture.

Thats about the price difference between the Sigma MC-11 and a new Canon 7d. I have several full frame Sony and Canon cameras, but wanted to use a cropped sensor with the Sigma 150-600 Canon mount.when I need a little more reach. Like my Sony A6000. The Metabones 4 does a lousy job, but to be fair, its not made for Sigma lenses, so my options were the Sigma Mc or another camera. First thing I did was update the firmware of the camera and lens, and took it to my local wildlife preserve. Focusing was very quick. Not as quick as my Canon 5d, but close. I was not expecting it to be as quick as it is. My ratio of sharp to out of focus images went up big time, and this was in fairly dim light. Some of the birds I was photographing were wading in bushes and the lens went hunting for focus more often than I would have liked, and when they were within 20-30 feet focus was slow or not possible. This may have been the light. I intend to carry my 5d and the 70-200 2.8 for anything within that range anyway, so no big deal. Overall I am impressed and look forward to getting out this weekend, hoping for better light.

Once I got the item I updated the firmware. This took about 5mins. I have a native lens and this MC-11 made my Canon 85mm 1.8 work like a native lens. Also all my other canon and sigma lens worked amazing. The only complaint is on my bigger telephoto lens the adapter to lens interface is a little wiggly. I didnt notice any flaws due to this. Otherwise, for the price and what you get.....Big thumbs up and 5 stars. I will never have to by those expensive native Sony lenses again! Yeah!

I use this with my A7 II and its a great solution to using Canon EF lenses on a Sony FF body. It adds about an inch to the overall length of the EDF lens. I use it with a 16-35mm 2.8 L, 50mm 1.8 & 85 1.8. The Sony equivalents are either too expensive and/or not as good. OK theyre smaller & lighter in many cases but the EF lenses are a proven commodity, plentiful, sharp & well-priced. All lenses Ive used with the MC11 auto-focus very quickly, AE works perfectly & all EXIF data is included with the file. I very highly recommend this adapter.

Im using this with my 18-35mm Sigma Lens, 30mm 1.4 and also a Canon 50mm 1.4 and 85mm 1.4. This this is awesome. It is built exceptionaly well and handles all my lenses perfectly. The Sigmas are a bit slower than the Sony Natives but this converter makes it happen. On the Canons, it hurts sometimes but again, definitely worth buying this and saving yourself some cash. Best converter out there. If you have Canon EF lenses, this will not work. I would point you to the Fotodiox Pro Converter.

I am using it with the A7iii and a variety of mostly older Canon glass including Canon, Tamron and Sgma. Works best with the 24-105 Sigma I just bought, but all other glass also work fine, to varying degrees. My 70-200 2.8, actually performs better on this than my Canon. What you give up are some of the focusing modes, nut the ability to focus and do face and eye tracking in the basic focus mode. Highly recommended
