Having played with the Z7 a little more, in combo with the 24-200 and 14-24 2.8S, I have several new comments and questions.
If I expose for highlights, I can easily get banding in the deep shadows. I hear the the ii versions are doing better, I wonder if it’s valid for Z5 also.
Focus is disappointing at times. It’s probably the lack of cross-type focus points, as it is sensitive only to vertical details. Often when the light went down I had to tilt the camera or entirely switch to portrait in order to achieve focus. And this is with landscape shots. In a quick test at home the Oly E-M1iii was snappy where the Z7 couldn’t focus.
I still struggle with the stabilization, depends on how tired I was I could only get up to 2 stops of stabilization, sometimes not even that. I had to take 2-3 shot bursts to be certain, and this was with the 24-200 which has OIS.
Outside of banding the sensor remains quite good. Dynamic range is mostly very good, and keeps the colors well into higher ISOs.
Still on the fence about the 24-200. Multiple instances of subpar sharpness alternating with good enough, not sure if it’s a stabilization problem, a focus problem or just lack of sharpness at certain focal length/focus distance/aperture combo.
I’ll have to compare in an organized matter with the Oly 12-100.
