Excuse my lens-ignorance. I've wandered all over the web and I can't find the exact information I'm looking for ... so here I am!
I know of someone who is selling two Protars. One, 140mm f18, and the other, a 180mm f18. I believe they are not Protar V's.
Can someone please tell me which formats these lenses cover, how much they are worth and where I can find more information and testimonials about them? I'd really appreciate it.
