If a student came up to me and had a camera as you described and wanted to know if it was worth the $150 to $200 it was being sold at -- I'd tell him to go for it. At $300 I would want to do comparison tests like you seem to have already done with your other 3.5E..

If the camera was originally mine and it had those defects in the taking lens, I would consider the defects as marks of strong character -- and would use the camera as if it were perfect. I use a lens shade all the time on my Rolleiflex, anyway. Buying such a camera to use as my main MF camera is questionable. The main question would be if I could afford a camera in such good condition and perfect glass!LOL!
