Do you guys still shoot analog? I do it infrequently now because I don't develop my old film any more (2 kids doesn't leave me much free time) and it isn't cost effective to drop $9-12 a roll for processing. Still, I really enjoy that Pentax especially with the 50mm. Just a lot of fun to shoot.
Another cool lens I picked up on Ebay cheaply is the M42 mount Auto Chinon 35mm 1:2.8. I like this especially for movies on the m4/3 cameras. Pictured below on my old Olympus PEN E-P1.
