Re: ZEISS FE 24-70 gets DxO marked !!!

even compared to crop censored peers?

A crop lens ought to perform better (especially in the centre) on crop than a FF lens.

The FF lens might be a little more even; but the point is that the pixel density on a crop sensor is such that lenses are designed for very high sharpness over a smaller field. An FF lens has to be sharp over a much wider field, but since the pixel density is lower, it isn't as sharp per unit area of its field, if that makes any sense.

Anyhow: bottom line is that peak sharpness for an equally good design on crop should be higher with a well designed crop lens than a FF lens.
