I have recently purchased a canon T2i, but am still relatively new to the whole interchangeable lens stuff. My friend has a Tamron 20-200mm lens and I was wondering if there was some sort of converter out there that would let me mount this on my canon? Now I'm assuming if such a product exists it would probably lower the quality of the overall product slightly (probably something to do with the focus) right? She said she'd let me borrow the lens whenever I wanted though, and that's why I'm so interested. So has anyone heard of anything like this? I looked into it but haven't come up with any results yet.

Tamron makes a bunch of different lenses for different mounts. There is likely a converter out there, just find out what kind of camera/mount it is compatible with. Tamron, Sigma, Tokina, Zeiss, etc. are all third party, whereas Canon, Nikon/Nikkor, and Sony/Minolta make lenses exclusively for their own SLR cameras.

Also, you won't lose any quality. You will be cropped in at 1.6 as you are on all lenses, and autofocus will likely be unusable.

Just to clarify, there is a chance that the Tamron will mount directly onto your camera. If your friend has a Canon camera, then you are good to go. Tamron primarily makes lenses to mount on bodies manufactured by other brands, like Canon and Nikon.

If your friend's Tamron lens is built to mount to a camera other than Canon, then pop over to B&H or some other photo supplier, and look for Lens mount adapters.

Thanks for the replies guys I appreciate the help. One more question: will the quality of the lens adapter hurt my camera at all? I found one for thirty bucks but I don't want it to damage the mount.

I can't speak from experience, as I've never used one. But it seems unlikely. I'd suspect if anything it would negatively impact the focusing abilities. Most likely a cheap adapter like that isn't going to be able to connect the lens to your camera electronically, so autofocusing won't work. You may be limited to manual focus.

I'd be alright with that. I wouldn't be using it all the time anyway. I was looking into it simply because this lens became available to me, it's not an urgent situation or anything.
