Klaus, this is an incredibly important review as the lens is very new. Please try to make an effort for an APS-C review.

I believe, if you look at the data resulting from the FF test of the lens,
you can estimate the crop-results quite well. Distortion and vignetting
is already noting to worry about on FF, so this will not cause any
problem on crop. Also, the excellent center-resolution will remain
on crop and (due to the smaller sensorsize) will expand to the borders.
Albeit, borders and corners have not been bad at all in the FF test, they
were just less good as the center) ... so more likely than not, the
120-300/2.8 will prove to be an excellent lens on crop as well.
The only question is ... is it the lens you need for a certain application?
