Database of MTF charts?
1

Is there a database of MTF charts somewhere?

Specifically, one that maybe has MTF charts for major FLs on a lens, such as on a 24-70 major FLs found on versions of the lens like 24, 35, 50 and 70mm?

Just wondering for the sake of comparing similar lenses from the same mfr.  I know each mfr has their own set of MTF charts and that each mfr may represent this data differently, but from what I can see, it's usually at the wide and tele ends (if it's a zoom) but not in between, as some people may never use one or both extremes of a lens.

I know PL does have some of these charts but it's only for lenses they test.
