I recently bought the Pentax SMC M 50mm f/1.7 and the Takumar bayonet 135mm f/2.5 lenses. Neither came with either cap, which surprised me. Anyhoo... the 50mm is 49mm, I believe and the 135 is 52mm. I'm looking for lens caps for these. I can find generic ones, but I'd love to find the correct ones with logos, or at least something from the correct era. Also, I need the rear caps, though I'm not as snobby about any logos on them.
Shoot me a PM if you have them. Thanks!
