"Pardon me?" you may think, but it is about the effect of age/condition of lenses and the effect on image quality.
I have a c-mount Kinoptik 2/25mm and just got for test a Cameflex (CF for short) version of the very same optic.
Left the results using the CF version, right the c-mount version, both shot under identical conditions just seconds in between using my GH1.
First the full image, then as a second pic a 1:1 zoom into the center of it. Reasons for that massive difference?
The CF version has a scratched rear element and some fogging on the rear element only visible in strong light against a dark background.
So be careful what you buy esp. on ebay and/or ask the right questions early enough!
