Micheal. I will just corroborate Eric's statement. The M-mount 503.5 is a better lens than the LTM version - partly because it is easier to use (at least you can set f-stop without finger prints on the glass!).
It works fine on a SOMKY and is actually very good as a close up lens - though I would stop it down to f8 for that.
