My brother gave me some lens meant for his T70 film camera. I have a Canon Rebel T7. I know it needs an FD to EOS adapter with optical lens.
Can anyone suggest one that won’t degrade the picture too much?

Hi @smodette it’s not worth your time adapting FD lenses to the EF Mount. All adapters with optical correction result in a 1.26x teleconverter and no focus to infinity. There will also be no kind of automation like EF lenses have. Also it will difficult to manually focus the lens. Since the viewfinder has no focus aids like a split prism or micro prism. The optical quality of FD lenses won’t match any EF lenses including older ones.

"too much" is wholly subjective. Most, but not all, people do not hate the Vello version for just $29 on B&H. That seems a reasonable first choice, then you can decide if it is "too much" degradation and also decide if you still want to use the lens despite all of the shortcomings that deebatman316 has pointed out to you. the K&F version is 4.4 stars on Amazon for $37
I have no hands-on experience with either and cannot recommend them personally, but it seems that given deebatman316's input you should not make a big investment into this solution.

If I choose to move forward anyway, is there an adapter you would recommend?
