Lookin at that one, another auction stated that this has 52mm threads, my old AE1 35mm has a wide angle and a zoom lens, 52mm back.

It seems like a long shot, but would it be possible to use the lenses I have now with my A510 digicam?

I havent had the chance to handle one of the lens adaptors so I have no idea how it works, it looks like it's just threads in the pictures.

you are not correct in thinking that your FD mount lenses have a " 52mm back " . they have 52MM OBJECTIVE LENSES(front elements).

That adapter is for the items specified and not an adapter to FD mount( which I can see not way to make EVER )

K, that's what I thought but I figured I'd see if it was worth researching further. After posting that I figured that focusing would be a pain anyway if it did work...thanks.
