For sale is Canon FD to Canon EOS EF Camera mount adapter. It would allow infinity, if you could mount the lens. 

But problem is that it does not mount on the lens. It seems to be factory design defect. when I try to mount the lens, it hits canon FD lens aperture pin and I can't make it lock on the lens. So you could drop the lens. This adapter needs modification and doe snot work in as is condition. Again, problem seems to be with a design. You need to cut a notch for the FD lens aperture pin to go into, or it will not work. 

Item is sold as found and as pictured for parts, or repair. Again, it does not work. And it is sold for parts, Please no returns on this item.
