I've been using old Pentax lenses on my NEX-3. It's pretty cool, as you can get a very good, very bright F1.7 50mm Pentax lens from the 80s for well under 100 EUR. And it's fun to combine 30+ year old tech with very recent digital tech, I don't get to do that all that often. The lack of autofocus is annoying, though -- manually focusing on a NEX is much more annoying than on an old Pentax --, and a lens designed for the NEX could be quite a bit smaller.
