It's always possible to take nice or interesting photos, whatever camera one is using. However, when one is thinking of spending a significant amount of money on an upgrade, one needs a comparison with one's existing equipment in order to assess if the upgrade is worth the money.
For example, one of the major attractions of the Z7 and 24-70/F4 combination, is the 'claimed' better sharpness at the edges and corners. If I were in possession of a Z7 and 24-70 S, one of the first tests I would be doing is comparing edge and corner resolution with my Nikkor 14-24, at 24mm and F8.
One of the main reasons I bought the Nikkor 14-24/F2.8 many years ago, was because the zoom was claimed to have the performance of many highly regarded primes at specific focal lengths within the zoom range. My own tests also confirmed that edge and corner resolution was far better than my then current wide-angle zoom, the Sigma 15-30 mm.
Having recently returned from a trip to China, I came across the following shot when processing my RAW files. As I understand, the location, if not the actual peak portrayed in the photo, is named 'The Beginning to Believe Peak'.
Apparently, some Chinese character in the ancient past was very skeptical about the claims of the wondrous beauty of this area in the 'Yellow Mountains'. When he visited the place himself, his opinion gradually changed, and he gradually began to accept and believe that the reports he'd heard, of the magnificence of the mountains, were correct.
Sounds similar to the current problem with the Z7.
The 100% crop in the attached 3 images reveals a significant fuzziness that I hope would have been reduced had I been using a Z7 with 24-70 S, at 24mm. The camera used for the attached shot was the D810.
