Fair call. Apart from say a mountain, I can't see using a 500mm for landscapes as very common. Isn't that why wide angle is so popular?

That was a very useful answer BTW, as I'm interested in FD lenses mainly for telephoto uses.

I'm well aware that FD lenses can be used on EOS bodies with an image correcting

lens adaptor. From what I've read this is effectively a tele-converter to

correct for the different mount lengths in FD vs. EF.

Since the low end DSLR bodies have a 1.6x crop, is it really necessary to us the

standard FD to eos adaptor, or would a simple mount converter (like an eos to

Nikon adaptor) with no optics work?

This would effectively be the same as a macro extension tube of a few mm.

Would this lose infinity focus?
