However, while this other website agrees with the resolution and contrast findings, it contradicts the chromatic aberration data, and isn't too flattering. erphotoreview.com/wordpress/?p=3542

Is there something I am missing? Can anyone help explain?

Referring to my previous post, it's too late to edit it. I think I may have found why that site displays very bad CA data: he is photographing the CA line pattern at a slant, and the resulting bokeh is causing the severe distortion at edges. Click on the "Lon CA" tab to see what he is doing. This is the way to test DoF, but I haven't seen other sites do the CA that way, as measuring CA when in focus in center and out of focus at edges is NOT the way to do that.

Very sorry if I caused any confusion - please disregard the link to the erphotoreview wordpress blog.

I'll prefer to use the data on ephotozine or on photozone.de in the future.
