Would you buy a camera with lens coating issues?
I bought an inoperative "UG" rated Rolleiflex 3.5E Planar from keh to see if I could fix it or at least use it as a parts camera. I did a CLA on the shutter and wind mechanism, cleaned it up, and repaired the meter. Now it works perfectly and looks very nice.
As expected, the taking lens has defects in the coating - not major - but you can see small cloudy spots and tiny pits if you hold it just right. The viewing lens had some fungus on the rear surface which was easily cleaned but left some scarring in the coating. It also looks like some separation starting on the edge (only visible when the lens is removed from the camera).
I took a roll of B&W indoors and can see no difference in sharpness from my almost mint condition 3.5F Planar whiteface. There may be a small loss in contrast.
I'll probably sell this camera when I finish fixing it up. I need to replace a piece of leather on the viewfinder and a couple of fasteners. The meter cover is broken of course and it would take $50-$60 to replace it.
My question is how much I should invest in this considering the lens defects. Would you even consider buying a camera like this and how much of a discount would you expect? You would be buying a Rollei in above average cosmetic condition in perfect working order, cleaned, lubed, and adjusted, but with a lens with issues.
