What lens to buy?

Yes, thanks, I didn't know they used a microscope to inspect. I've also
seen folks post links to the Japanese web pages of the major
manufacturers with MTF charts. Of course that's quite possibly biased &
I can't read anything but the numbers.

I've heard it said -- with how much truth I don't know -- that
Canon's MTF charts are based on the theoretical, not the measured,
performance of a given lens.

Sometimes it only makes sense to focus our attention on those
questions that are equal parts trivial and intriguing.

As I've stated before, NEVER, trust OEM MTF graphs. Unfortunately,
independant, single rig testers like photodo don't seem to be around
anymore. Photodo hasn't been updated in a couple years, and at that you
have to 'trick' the graphs to appear. Tedious and getting dated.
