Just because that photographer didn't see the effect doesn't mean that it can't happen in certain circumstances, though. Plenty of photographers have shot thousands of compressed .ARW photos and never noticed compression noise artefacts on high contrast edges. Some still argue that the problem doesn't even exist in normal shooting. I have numerous photos that prove otherwise.

Well,
I'm certainly not picking on the new kid. I like Sony cameras... you know I do. But I see no harm in acknowledging that this is a potential weakness in certain shooting conditions. It's a minor one for most people, I suspect, but a weakness nonetheless. Better to know it's there, then the photographer can make appropriate choices to avoid it happening. After all, you wouldn't want to start processing your photos after a day's shoot, and find that some of your favourites have this artefact. If that happened, it would be cold comfort to be told that someone else took 4,100 shots without it appearing, right?
All things considered, the A7 MkIII looks like a fine camera to me, and one I'd be very happy to own. Like every other, we can't expect it to be perfect. But early indications suggest it's very good
Although this is a non-Pentax thread, @photoptimist makes a very good point... some of the complaints levelled at Pentax equipment are for equally minor things. But goodness me, it seems like an impossible task to convince people of that...
