More GAS, I did pick up a Contax II from 1936 a few weeks ago. Ran through the shutter and it worked then it didn't when I put it in bulb mode and now I can't get it out of bulb mode with the shutter stuck open. Will probably message Oleg on getting a CLA on it and the lens.
Reading past posts, I guess that 5cm F2 has rather soft glass eh? Mine came with a matching uncoated lens. The haze cleaned up, but it still has quite a bit of micro scratches on it.
Still not sure how I am going to get comfortable with the Contax II grip, it feels awkward along with the different direction of focus
