It is strange in the resolution figure: the FF edge resolution is better than the APS-C edge resolution at f1.4. Is this caused by the different resolution of the camera sensor?

The Lenstip test of the Zeiss shows its APS-C edge resolution to be little better than the full-frame edge resolution up to f4. Their recent tests of the Samyang and Nikon 35's don't do this, so it looks like a characteristic of the Zeiss-- very sharp in a smallish disc in the centre, but falling off to a fairly even but lower resolution over most of the picture on full frame.
