Would this work with to mount a AF version Sigma 24-70mm F2.8 to a canon 5d mkIII? Also would the autofocus still work with a sigma lens?

My experience with adapters so far is the autofocus has not worked. Your camera is totally manual

The adapter I got only allows the lens to fit on the canon, but autofocus does not work. I don't have a sigma lens, so I'm not sure whether yours would autofocus.

I use mine on a 7d and a 5d Mark III, it works perfect on both. I would assume it would work on the 70d too, seeing it is a crop sensor like the 7d.

I own the 100-400, 4.5-5.6 L lens. Autofocus does't work on the 7d, but if you use it on live view or mirror lock-up it does auto focus. Good luck!

Although i havent tried it ith that lens specificially, it works with all lens that I have tried including the Sigma 50-500. Auto focus may not work very well however because of the loss in aperture. I also found that instead of individual sensor focus, group sensor auto focus works more reliably.

I'm using Sigma lens on my Rebel T4i. I bought them for my Canon Rebel XT years ago. These lens have Canon mounts on them. I didn,t get enought time with this camera to see if it is as good as the older Rebel

I have a Sony A7s, which has the same mount, and it works perfectly. There is no autofocus or aperture control so it will only work with an older Nikon lens with aperture ring. There is a little play in the mount but I have not noticed any light leaks or problems. I shoot video and use this with a Nikon 70-200 2.8.

It works fine on my 60d. So should work fine on 70d. It is slower to focus than the Canon version. Mine is very sharp. Mine does not have IS, but that does not bother me. I think it is well built, and the price cannot be beat for a 2.8 zoom. If lack of IS and USM do not bother you, it is a great lens.

It might fit, but if it does, you will have no autofocus, and you will have to use the manual mode for setting the aperture. I only use mine for when I hook up my Sigma 600mm mirror lens. Then everything becomes manual.

I believe it is. The Sigma can be had with either Sony A & E mounts. I use the lens with a NEX7, E mount. The lens with an A mount and used with a LA2 adapter for auto focus & exposure. To set the aperture go to your camera setting. Aperture. Set what you want & the shutter speed sets automatically.

It's working fine with the autofocus mode on your lens, would also work with the manual focus but you would have to preset the focus on the lens. Michael

I've used it with 18-250 Sigma, 10-24 Tamron and 60 macro Sigma, all in A mount on my a-6000. Don't know if it will work on a-3000, but if it is E mount you should be able to use them with manual focus

I use it on a d3000 and d7000 . Only time I have issues with it is when it's used on my APO 150-500 sigma lens . The lens has trouble auto focusing .

Yes, the Canon mount of this Sigma lens, will work with any Rebel/T-series, 50d, 60d, 7d, 70d, and all full frame dslr bodies (5D, 5D Mark II, 5D Mark III, etc). Keep in mind that on your T3i body (aps/cropped sensor) the focal range will be approximately 112mm-320mm due to the 1.6 crop factor of the smaller sensor.

Alicia, I have not used that combination. I have used with A7r and Canon Lens. Works good enough. Auto focus is not as fast as the A7r with a a native Sony lens, but works. I must say though I sue manual focus most, DMF mode. With the wide angle of the Sigma, and the nature of what is shot with such a lens MF would be about All I'd ever user with that lens so any slowness. If you were shooting wildlife with Telephoto > 200mm then the AF is not fast enough. The electronics does work and EXIF data for the lens is stored with imageBottom line: Opens up other lenses for the Sony. Slower auto focus. Alicia, I have not used that combination.

It will work with 3rd party lenses made for Canon AF Cameras. EF or EF-S mounts are both supported by this set. Occasionally an 3rd party lens (i.e.Sigma, Tokina, Tamron etc.) will not function on newer bodies and require their mfg to update firmware in the lens. This is pretty rare though. I do not believe the original question was referring to Sigma lenses made for Sigma cameras, but rather those made for Canon. Sigma for Canon is quite popular.

No, it will not. It works just with a limited number of SIGMA lens. Have a look on the SIGMA website. It does not work with any lens of different company (Nikon, Canon, Pentax ecc.). Better: it can increase magnitude of 1.4 but you will loose both autofocus and automatic exposure. Frankly speaking, I use it (not frequently) together SIGMA 300 mm f: 2.8. The autofocus is not very precise, slow and the quality of the photos is not fantastic considering the whole amount of money that the lens (both) costed. Regards

Yes. I use it for the Canon 7D and Canon 5D Mark ii. However... it's a pain to try to rack focus, but it still gets the job done.
