Thank you for your replies, guys!
I have shot mostly digital with a 5D mark III, occationally as I wrote above with the EOS 30. Of course with the same EF lenses. I felt a need to revive my photography hobby and decided to explore Canon's FD system and use film more. Suddenly I had five FD mount cameras (two FTbn's) and a 28mm and 50mm (both 1.4 and 1.8). I'm leaning towards trying out the EF first. Regardsless, I think I'll have a lot of fun in near future :-).
