In my book, MTF curves are sort of like Revelations in the Bible. You really don't want to read them. ;-)

they're actually not as horrible as they first look. i think it's easiest to get with someone looking over your shoulder pointing things out, but these resources are pretty good:

http://www.normankoren.com/Tutorials/MTF.html (a bit more dense)

the schneider link ralph posted is also very good.

if these make your eyes glaze over one of us might be able to help.

i like mtf curves ... you could go to your grave never having heard of them and have no regrets, but i find they clarify some things about optics that used to be mystifying. and also i might be a geek.
