Anyone know of a good primmer on-line (or care to explain) how to read an 
MTF graph?  This was spurred by looking at the MTF graphs on Leica's 
web-site for the 2/35 and 1.4/35 lenses and going "hunh" . . . Not that MTF 
graphs are the be-all and end-all, but I've been sauntering through my 
photographic life for the last 20 years without knowing what they mean. (not 
much of a theory-head when it comes to optics).  So, here's the softball 
question:  what kind of numbers (or what kind of curves) make a lens 
"better" in MTF land?  What about the 1.4/35's graph indicates that it is 
such a winner?

bemusedly,

Ben Marks
