Contax iia dim rangefinder
I have a beautiful Contax IIA with a Sonnar 1.5 and a couple of other lenses. I had a CLA and the camera works like a gem. However, the rangefinder patch is very dim, almost to the point of being useless. I can shoot quite happily at mid to small apertures and guesstimate distance but I'm clearly not making much use of the Sonnar qualities wide open.
I would like to get the mirror re-silvered. I do have access to sputter coaters and could recoat the mirrored surface with either gold or Pt/Pd. My questions is: Is it worth having a camera shop remove the relevant piece for coating or am I better off sending the camera off to the pros for re-silvering (if so, who would you recommend? I'd rather not be without the camera for 6 months!). Also, does anyone have a repair manual/document that shows the internals?
