Last night I snagged a package off Craig's List that I'm pretty excited about. An old Spotmatic II body, M42 Vivitar 135mm f/2.8 (good condition), M42 SMC Takumar 50mm f/1.4 (lovely, flawless as far as I can tell condition), a 2x and a 3x teleconverter (forget the brand, Kenko I think?), 14 filters of various kinds (mostly Kenko sized for the 50, no idea what they are until I do some research), a couple small flash units, and assorted kruft (lens cleaning kit, straps, handy carrying bag etc). All for $100.
I'm figuring I'll keep the 50 and maybe the 135 and sell everything else. Including the A 50mm f2 which I hopefully won't need anymore with the new 50, I figure I should at the worst be able to break even and have an upgraded lens and a chance to play with a prime I've been wanting to try. I may also be able to take the focussing screen off the Spotmatic, but I'm not sure about that.
