>>3284501Also have a SMC Pentax-A 28mm f/2.8, not a great lens but the nicest feeling focus ring I've ever felt. Had a 135mm f/2.5 (can't remember if it was M or A) which also wasn't great but I made a good profit on it. Replaced it with a CZJ 135mm f/3.5 which is sharper wide open than the Pentax was stopped down even slower.
