I'm looking to dip my toe into the world of adapted lenses and I'm not really sure where to start. I recently got adapters for both Konica and Pentax (K-mount) legacy lenses to fit my E-PL1, but as of yet have no lenses. I'm hoping to get some good, relatively cheap glass to start with to see how I enjoy going fully manual. A good place to start seems like a simple portrait lens. While I understand that lenses like the Konica 57mm f/1.2 are fantastic, I'm looking for something I can pick up in the $10-80 price range (think yard sale), not a multiple Benjamin investment. I've looked through this and other forums and the popular inexpensive options for these systems seem like: Konica 40mm f/1.8 Hexanon Konica 50mm f/1.7 Hexanon Konica 50mm f/1.4 Hexanon Pentax 50mm f/1.4 SMC Pentax 50mm f/1.7 SMC I'm not wanting to start a Konica/Pentax religious war, just looking for any experiences you have (good or bad) with these or any other lenses I've overlooked that fit my vague criteria. Also if you have any tips on how to shoot with any of these lenses (e.g. "this lens gives its best results when it's stepped down a couple of stops" or "invest in a good hood for this one to prevent lens flare", etc.) that would be much appreciated as well. Lastly any general tips on how to identify a good older lens would be welcomed. Thanks in advance!
