I bought this lens last week at a pawn broker for $7.99 and received my PK adapter ($29.00 plus $7.00 shipping) this morning. I'm stuck in the office, so not much opportunity to shoot. But I had to try the lens, so I had this guy pose for me. Don't ask me why he lives in the office. GF1 with SMC Pentax-A 50mm 1.7 @ f/2.8, 1/80, iso 800.
