What the experts say
Techradar had thought that the Sony Alpha A7 III was the king of the premium cameras, However, the Z6 has given them real pause for thought. A high-resolution Electronic View Finder, great burst shooting, 4K video and ease of use all count for the Z6.
Digital Camera World described the image quality of the Z6 as "just awesome". It may have minor niggles like a small buffer and a slightly poor battery life, but this is a great camera in its own right and not just a consolation prize for those who can't afford a Z7.
A single card slow and comparatively weak autofocus (compared to DSLR) was not enough to stop Digital Trends giving the Z6 four stars. It's excellent image quality (even at low lights), ISO range, and 12 frames per second burst function shone through.
