Okay, if anyone wants the high resolution charts for any of the following lenses, let me know & Ill e-mail them to you; they range from 300-400 k for a single focal length to 860k for the 18-55 and 1164k for the 50-200. (Sample of the 18-55 is attached). I'd be glad to post them if someone could show me a way of putting up the large files and they don't lose the necessary resolution:

18-55 kit lens
50-200 kit lens
50/1.4 FA
50/2.8 F macro
24/3.5 M42
55/1.8 M42
100/4 M42 macro
150/4 M42

I hope to do the 28-90, 80-200, and 21-35 Sigma sometime soon, but I've got to take a break right now - it takes a couple of hours of cutting and pasting to do one of the zooms.

Okay, I've now finished making charts for all 11 lenses. Contrary to my earlier statements, I can see differences between lenses and f-stops; however, the maximum resolution of several of them seem to be very similar - no real standouts. I still wonder if the better lenses aren't resolving beyond the capabilities of 10 megapixels at the "three star" level of .jpg to distinguish, and therefore, maximum resolution seems to be about the same? Again, if anyone wants to see any of these charts, let me know.

I just realized I didn't test my 100/3.5 Vivitar macro - damn, I know I won't rest easy until I include it - that will make an even dozen lenses! I think I'll also try RAW with it to see if that affects the maximum resolution.
