While shopping at an antique store a couple weeks ago I came across a clean Pentax MG with a mint condition Pentax A 50mm F1.7 and a couple other do-dads and trinkets all for the price of $45. I tested out the body with some even cheaper film from a flea market that I got for ~$0.25...age unknown ISO400 Fuji or Walmart film.
The good (A50/1.7@F1.7):
(with a little fixin')
The bad (M135/3.5w/fungus@~F8+light leak):
The ugly (not sure on the stats of this one...maybe Gemini 28/2.8@F11+flash+bigger light leak)
I think I'll have a good camera once I fix the light leaks. The A50/1.7 is awesome on my KX DSLR.
