I had a Z7 for a couple of months back in 2020. At the time my main system was Olympus (EM1.2). Of course the IQ was better with the Z7, but I found its features quite lacking compared to the Olympus. It felt like a previous generation camera compared to the Oly. The lack of livetime zebras or overexposure blinkies was a real deal breaker in the end. But Z has moved on a lot since then and I sometimes wonder if I should have persevered with it. But the S5 is a much more capable body than the original Z7 in terms of features, even if the EVF experience isn’t too good.
But it has to be said that the Z lens range is now notably better than L mount with some excellent options like the 24-200, 24-120, several pancakes, and multiple options in the wide-standard zoom range.
