The images certainly look very sharp, David, and the third image has a lovely mixture of colors. However, what attracts me about the new S lenses for the Z7, is their improved edge and corner sharpness. Have you investigated this issue and done comparisons with F mount lenses?
I’ve been using the two S lenses and the F-Mount 70-200 f2.8 VRII mostly. My feeling about the S lenses is that they are
very clean. They seem sharp everywhere, and seem to have very little color cast. I think this is even more true for the 35mm than for the 24-70. That lens has a clarity that seems quite special. I’m sure part of the color observation is due to the camera's improved white balance algorithms; that seems to me to be a significant, if subtle step. But I do think the lens plays a part as well.
I have been very impressed with the performance of the 70-200 on the Z. Focus is very quick, even using the TC14. (I think I have v2 of that.) that’s a very sharp lens as well, and seems very much at home on the camera.
I have a good set of AI primes, which are, of course, not in the same class as those three lenses in terms of sharpness (especially wide open) but which are a pleasure to focus with the EVF. I’ll post some images with them when I get a bit of time.
I’ve been meaning to do a head-to-head comparison with my 24-70 f2.8 (non VR version) but haven’t gotten to that yet.
