The lens is marker h16 rx. I'm just wondering what makes the Kern lens better, as far as optics go? I'm guessing the Som lens would be more likely to flair? Anything else I should be aware of, I just shot my first test roll so I guess I'll see.
Also, when shooting with the rx lenses on the bolex reflex, I don't need to compensate exposure for the light lost in the prism, Correct?
