I have a Sony A7. Will this lens work full frame and auto exposure/focus with a converter? Many thanks.

This lens works on full frame but I am not sure how the electronics would work with a converter

I only use mine as straight Nikon mount. I'd suggest asking the converter companies such as Fotodiox. Also try www.diglloyd.com/articles/ask/lenses-LensAdapters.html

No, it does not work without adapter. This lens has A - mount. Sony A7R has E - mount. You need LE-EA4 adaptor.

I have both the 150-500 and 50-500 Sigma lenses (A-mount) and it works with both of them. I use them on Sony E-mount cameras with a Sony A-mount to E-mount adapter. IS works with the teleconverter but AF does not. All other function work. This converter works especially well with these lenses for wildlife subjects.

Hi Lina, we cannot guarantee that your Sigma lens will work properly on this Sony Alpha a700 like auto focus, etc. You may refer to sigma support for this issue. -Ely

Yes, it works well. However, my problem with the A7 was the auto focus failing a lot. I returned it.

First of all, it's going to always be manual focus. I do have this adapter with A7, not A6000, but the only different would be the censor size. It's should work as expected on a6000. There is no glass/lens so it's should not effect any image quality.

AS far as I know the lens has the e-mount system which works on all Sony E-mount platforms. I am pretty sure it will work ( take photos ) but the lens is only a crop (smaller) sensor. So in essence you wont get a full frame image out of this lens, but a proportionally smaller image, about 16.1Megapixels.

Hi Visionist, when using it with the A7II, the built in SteadyShot of the camera body will be in effect. This is a telephoto zoom lens. Thanks_Mitch

You can use it on Sony A7s. BUT first you need to buy the adapter ring to mount the lens on the camera. That adapter ring has M42 female thread (lens side) and male bayonet (camera side). Then the lens will work on All-in-All manual mode. I hope it helped. Zonesystem

Works fine on my A7r. You must use full frame lenses or you'll get vignetting. DX lenses will connect but will create vignetting. To get the A7 or A7r to trigger, you must change a setting in the menus to allow it to trigger with no lens attached.

Hi, I apologize but I cannot find the dialogue from the seller where we spoke of this. I believe this lens worked for both full frame and those with a crop factor. I tried to verify via Tamron's site direct, but can no longer find the lens. You would need to find one with a mount that fits your Canon, or find an adapter.

it is a full frame lens. i ordered mine with a nikon mount i beleave it also comes in a sony mount. see what mount your camera has & go to sigma web site & see if it fits. if not check on a adapter. i got one for my sony fs700 vidro camera. it is a good lens, i love mine. note: the auto functions do not work with the adapter i have but if you order the lens with a sony mount & get the right adapter i think they will.

Yes. works perfectly for me. Be aware, that when using the adapter you'll need to use the Sony A7 in manual mode. That means manual focus, which is easy with the great focusing tools on the A7.

I don't own an a7 but assume it will work. I am using mine in Paris with my Canon 5D and 24-105 Lens with no problem. I really like the portability.

Gary, it's a full frame lens but to use on A7 you need an adaptor (la-ea4).

I'm sorry, I don't know. I have never used the A7, but what I know about the adapter is that it is a manual one, you will loose all automatic functions of the lens, so it works best for the old Nikkor lenses, before they became all inclusive and automatic. Also as others suggested this is a full frame adapter, we also use it on the NEX 700, but there it uses only a portion of the frame. I hope this helps.
