1. Minolta MC Tele-Rokkor PF 135/2.8
Beautiful glass and coatings, barrel can occasionally come a little loose, just push it back in.
Otherwise...amazing shooter.
$55 USD shipped to US/Canada
2. Canon LTM 50/1.2
Includes a new LTE-GFX adapter from Fotodiox.
Front element looks like it lost a catfight. Vignettes on 4:3 but will cover most other formats well enough.
Soft and dreamy at 1.2, it's pretty sharp at f/4 and smaller.
$230 USD for lens and adapter.
Or $140 for just the lens.
Includes shipping to US/Canada.
