I have just bought a lens marked 210mm Commercial Astragon.
Questions:
1) Who made this lens? 2) What is center and edge sharpness for this particular lens? 3) What year was this lens made? 4) Is this lens achromatic?
I can't find ANY information about this lens on the web, other than some vague i nfo about its image circle (which is not worth a whole lot to me).
Please help me, thank you.
