I have an e-pm1 on the way from Cameta. It's my first ILC since my AE-1 Program. I am very short on money. I ordered the epm1 with the kit 14-42. I'd love to add a faster lens To the party. I have the canon 50mm 2.8 that came with the ae1. Is it worth it to get the FD mount? I have a couple of other nondescript FD lenses I could play around with. If not, what are my other options for under $75 or so? I appreciate any advice.
