#a7iii

i've been on a tropical trek last week, used my sony a7iii, and every time i hit iso 1600 the sensor throws these weird ghosting lines. also the hdr auto bracket from camera gave me 8 stop exposure that just flatlines. seems like the sensor is miscalibrated? i read in the sony support doc the A7iii was fine but my unit just won't do. anyone else? also idk why the autofocus on the a7iii jumps to the wrong face in bright sunlight. receipts: sony a7iii, sensor model: Sony EXM5, firmware v1.8.9, firmware update 2023-03-15. the issue started after i used the sony speedlight k3 flash in humid climate. idk if it's a known bug or just a hardware glitch. i don't know how to file a claim with sony but i'm asking for community help. please share if you have the same
