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.
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.
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.
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..
I don't think I've given my opinion on this adapter yet, but I used it a lot when I switched from Canon EF to Sony e in 2016 while I was waiting to gradually replace my L lenses with G or GM lenses at the time!
I have to admit that with my bodies such as the A7M2, the A7R2, the A6000, the A6400 and even the A6500 with which I used it the most, this converter had left me with only very mixed opinions... But that was before I used it with my A7R3A and with my ex. A6600 or my current A6700! I covered a whole event with the A7R3A, the MC-11 and the Canon EF 70-200mm f/2.8 L II IS USM at the end, with, I must admit, very few AF misfires and truly impeccable image quality in the end!
So, with bodies from the A7 generation 3 upwards and the A6600, I think I would recommend it, especially with certain Canon L lenses (not all of them).
!!!CAUTION!!! It is absolutely not compatible with Canon EFs lenses for APSC !
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.
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.
