Originally posted by normhead I guess you missed the part where it states you can't compare different systems using these tests. I love photozone but because they have not tested even one third party lens on both Pentax and Nikon, there is no way to determine what those ratings might mean in relation to each other. I pretty much ignore them in comparisons across different brands.
Dear friend...
I don't compare LENSES at different systems. I use ONLY LW/PH data.
I say about maximum resolution of APS-C or FF cameras.
Pay attention at the data at the left side of tables.
2750, 3400 and 4000 LW/PH. It's theoretical maximum of concrete camera calculated by IMATEST.
You can find 24 MP APS-C camera which could has resolution close to 24 MP FF camera, but...
Not equal. Always LOWER.
To compare resolution of K-5 and D800 is nonsense. D800 has huge resolution.
K-5IIs, I guess, has not higher than 3000 LW/PH. D7000 with weak AA filter than K-5 has 2900 LW/PH.
