I noticed this before, but did not have the lenses you tested. now you published the results for the 85mm, which I do own. What is surprising me is the low center resolution for this lens (and for all your NEX-7 results). In practice I see a camera that has a higher resolution than the Sony a900.

I have made a simple comparison; a test chart (printed approximately A2, so not comparable with standard test chart), at such a distance that the test chart fills, horizontally, approximately 50% of the image.I changed the distance to make the subject scale the same. developed RAW's in LR4, with the same sharpening (amount 60, radius 0.5, detail 50 and masking 0). I had to change exposure a bit of the a900, since it gave, for the same f stop and shutter speed, a darker image.

717 is the NEX-7 and 2 is the a900.

It is clear that the NEX-7 has a light AA filter. there are a lot of color artifacts, including the colorization around black edges. and to me, the NEX-7 images seem to have a higher resolution.

Is it just that Imatest interpreted the results differently? Am I doing something wrong?

I know there are slightly more sharpening artifacts in the NEX-7 image, something I blame on the image being sharper to start with.

the comparison is show at 200%
