M5 has landed.
It is in beautiful shape. Viewfinder and rangefinder are crisp and clear, light meter works but is overexposing by about 2 stops, shutter sounds good (will test it tonight) and it is extremely smooth. I'm probably weird but I think it is gorgeous at pretty much any angle other than just flat on. Just finished a half roll in it as a test and will be processing that soon.
This Summitar is a good fit for the M5, the collapsing mechanism is jammed so it always stays out but the optics are clean and it is coated with 10 blades.
