First, I apologize if it sounded as I wanted to attack you. My question in the first paragraph of my mail was a rhetorical one, not directed against you. With regard to the 24 PC-E: I have it, and I know exactly what you mean. It certainly annoys me, and I will have tested my lens from Nikon's central service point in Germany when I get there in 3 weeks, and see whether something can be done. I hear many people reporting this problem, but not every owner (and not every review). Also, I think the lens' problem is a distinctly bowl-shaped plane of focus - I have noted this in certain scenes when fringes nearer to the camera do get sharp.
But I cannot believe at all that it is impossible to get these data DxO uses for Pc-lenses. After all, reviews are available, and zoom lenses are tested. Sharpness, vignetting, distortion, transmission, I cannot see any reason why this could not be tested. Also, why does DxO not provide data for Zeiss lenses on Nikon? This renders their whole strategy questionable, and I for my part am not going to buy this product of theirs for these reasons. I do think that the dependence on marketed products of most photographers necessitates an awareness of this relation in order not to get manipulated.
