Just wondering does any of you folks use the MTF Characteristics Graphs as one of the considerations in choosing a lens? These graphs of the individual lenses are supposed to give details on their contrast, resolving power...etc.

yes i do. it also shows which aperture will get the sharpest image. quite a good quide. example; the 300/f2.8 vs 300 f/4, it tally with actual results .

It's been somewhat helpful for me, but I do not rely on them entirely. Things like the degree of chromatic aberrations, distortion (pin cushion and barrel) are not mentioned in the graphs. Do read user reviews and ask for user's opinions as well in addition to looking at the MTF graphs.
