Demonstrating Lens Issues
I am having issues with my MC Kaleinar-5N 100mm f/2.8 (Russian: "MC Калейнар-5Н 100/2.8") producing lots of spherical aberration which I think is leading to the overall softness of this lens. It is very soft throughout the aperture range.
Everything has a spherical aberration going on at f/2.8 making everything blurred and soft.
I hear that others have pretty good sharpness with their versions of this lens so I am disappointed with the one I got and I don't think it is an overall issue with the build. Mine is a later one with the rubber focusing ring. Perhaps I should have gone for an earlier version?
