Hi all,
Hope the seasoned veterans in here can enlighten me...
I've read somewhere that lenses are optimised at a particular f-stop. Am I right to say that at that particular aperture the lens is sharpest? Or is there more to it?
Also, I've got a really clean copy of a Jupiter-8 that i'd like to use more. How do I check to what aperture is this lens optimised to? And if I'd like to change the 'optimisation' how should I do that?
Thanks in advance!
