Can an old film sigma uc zoom 70-210mm lens work on canon digital cameras

Sigma makes lenses with a variety of mounts to fit a variety of cameras. If the lens has a Canon mount then it will work with your XS. If has some other mount, Nikon for example, then it will not.

Sigma makes their lenses with a variety of mounts. If the lens has a Pentax mount then it will work with your K20d.

If the Sigma lens mount is a Canon FD fitting then you can get an adapter FD to EF that will allow you to use the old lens in manual mode. If your camera isn't designed to take EF-s lenses then they will not fit on the camera. My EF-s lenses will not fit on my 6D.

It depends on the lens mount. Sigma makes varieties of their lenses for different camera mounts. A lens with a Canon mount will be compatible with any current Canon camera. A lens with a Nikon mount will be compatible with a Nikon camera. Any one lens can fit one but not the other.

Hi
It is well known that some lenses made by Canon for the EOS film camera range do not work well with digital SLRs. Canon lenses work fine but it may be worth checking if the Sigma has a known problem with EOS digtal bodies.

Hi The 120-300 f2.8 is a full frame lens so it works on all canons with a eos fitting

yes ef stands for electric focus which is what your camera mounting should be check your mounting to make sure its EF and if it is go for it. also the mounting type might be in your hand book

I have the same problem. So far I've contacted Sigma (I believe this is the company that manufacturers the Quantaray lens for Ritz) and they requested I send them a photo of the lens. I just googled sigma lens to find sigma support. I will update you all with any response I may get.

Did it ever work on this camera?
I have seen some Sigma lenses that are auto focus on canon film cameras but then when put on the digital they dont work right. If you have used it on this camera then make sure the lens is clean.sometimes dirt on the front wil make it try focusing on the dirt. Next try focusing in manual focus to make sure the focus is working. Then take the lens off and then put it back on and make sure it clicks into place.

Let me know if none of those things work. also make sure to try focus on something close and somthing far away.

let me know how it works,
Caleb

The canon lens should work fine. Some of the Sigma lenses have to be converted by Sigma to work with digital. The last one I sent to them they only charged me $10 for return shipping. You can find their address online.
