Ok, since I've already responded nastily to one !@$ today I'll do it again.
Mustafa, what does MTF have to do with what you want the lens to do for you? Why screw around with trying to measure MTF when you can simply take a few shots and know whether the lens will do what you want it to? And why do you think a Soviet-made imitation Elmar will do what a Summitar does? Why not just use your Summitar and get on with your work?
I've said it once today, I'll say it again. There are too many damfools here.
