>>4272478I had an a7riii for a year
After some point, following a bit of travel and rough handling (aka being in a backpack), it just stopped taking perfectly sharp pictures no matter what I did (vr off, tripod, fast shutter speed, e shutter, still life...) unless I used manual focus and every few hundred photos I'd get a raw that was mostly pink lines.
On the other hand it fell in a lake before I got it, so I was able to buy it for $600 and sell it for $800, and it got rained on a couple of times
