This is a special cable. I would ask the Sigma importer Ott and Wyss. A normal USB cable with a mini USB connection will probably not work. The cable is included with the MC-11. If it is no longer available, you need the original spare part.

All full-frame lenses that fit on a Canon can also be used on your APS-C camera without an adapter. However, the Sigma 18-35 f1.8 is better.

Thank you very much for your contribution!

No, no, the adapter also works with EF S lenses, but it's not as responsive as a Sony lens. Happy holidays!

Only if you have a Sigma SA mount, and that will hardly be the case with Tamron lenses. The MC-11 is also available for Canon EF mount. The Tamron lenses can then work or not. This is not supported by any manufacturer. Sigma only supports its lenses of the Global Vision series. The others may or may not work. I think adapting is a stopgap solution.

Yes I used the 100-400 with the MC-11 on an Alpha 6300 four years ago. It didn't work badly. But it's only worth it if you already have the 100-400. The old Sigma 150 is also not officially supported by Sigma on the MC-11. It may or may not work. I haven't tried that out, though.

Yes the Ibis works with the mc-11

If a general answer is expected: No. It is possible that individual EF-S lenses will work, but no one can guarantee that. Sigma officially only supports its own lenses of the newer series with EF mount. Sigma itself does not build EF-S lenses. And in general about Canon EF lenses on the Sigma MC-11: They can work great, not so great or not at all. This is a combination that no one supports.

No, that does not exist and is not technically possible. Only DSLR lenses can be adapted to mirrorless cameras, because of the much shorter mass of the mirrorless cameras. There is some ultra-thin Chinese adapter with which Sony E-mount lenses can be adapted to Nikon Z lenses. I don't know if this works properly. But there is definitely no Sony E to Canon RF or even EF.

No, it is only a connection adapter from Canon EF DSLR to Sony FE DSLM. Since a DSLM does not have a mirror shaft like a DSLR, the adapter must be about 2 cm thick so that the focal length and the properties of the lens remain the same compared to the DSLR.

I also have an A7rii and the adapter. Works flawlessly

The converter contains the data necessary to ensure fast and smooth autofocus and image stabilisation with the compatible lenses. At the same time, they provide compatibility with the camera functions that ensure edge illumination and correct lateral chromatic aberrations, distortions and other problems. Exposure control is also taken care of.

According to my information, it is 125g.

Sorry but no it only works with Sigma lenses for the Canon. I have exactly the same lens but it does not work :-( Greetings Andreas

Yes, this adapter is compatible with your equipment.

Normally you can use this: Sigma MC-11 Adapter Canon EF an Sony E but after that you always lose in quality and often in auto-focus. Maybe look on some specialized forums. If you plan to use the auto-focus of your lenses I think it's dead.

I have the Tamron 70-200mm and it works. However, the AF is very sluggish and unusable, especially in dark light or at long focal lengths. My camera is an A7RII. I think your lens is even older, so I wouldn't rely on it being practical. However, the lens is not the best choice for an RIII anyway. The potential of the camera is lost. With Sony, especially with a 7R, you unfortunately have to bite the bullet and buy new lenses, even if they are very expensive. Otherwise, the expensive bodies are not worth it.

it "should" be working.. but nobody can really tell you if it does. if you have IS it wont work.. you should check online if peole already tried it.. because on some it works well and others less. and it also depends on which 70-300mm you have.. Canon has A LOT of those..

Well, the problem with the 18-35mm is that it's made for APS-C only. Unless you're working in Super 35 mode on the A7SII you can't really use it. AF should work though

Well this is difficult to answer. In theory yes but here are some restrictions: 1. If you want autofocus it will work only or mostly with sigma lenses that are compatible with this. You can find these here https://www.sigmaphoto.com/lenses/mc-11-compatible. 2. If you work with manual focus then it works great with all canon EF mount lenses. Some will also have some autofocus but this is not usable. Will not work with Tamron. I use the 50mm 1.4 with A7 and the images are amazing. I also have full aperture control. This is much better quality than the sony 50mm 1.8 FE which by the way is really a waste of money. Actually the kit lens is fantastic comparted to it. 3. I use it mostly with my a6300 where autofocus actually works very well with all my canon lenses as well as my tamron 17-50 VC and the 70-300 VC. I assume that if you get the A7Rii which has the same focusing system with the a6300 it should again work well. Bottom line its generally a good product but it depends on the camera that you are using as well as the lenses that you prefer. Hope that this helps. Theodore

According to my kitchen scales 123g without the protective covers.

It is an adapter to get Canon EF lenses onto a Sony E lens mount. It does not work with the Nikon F lens mount.
