Spent the weekend diving in somewhat cold water (6° C) and about 40-50 min into the dive the ISO and Flash settings started to act up. I would change from ISO 100 to Auto 3200 - 6400, jumping between values like a pinball machine, also the flash compensation would shown on LCD (+/- 0) and opening the Flash function settings menu would show either Manual (grayed out), ETTL, or MULTI/Ext. A.
If I tried taking a picture, the flash would either not sync correctly, or would be overexposed (I guess auto ISO at 3200 would do that).
My setting was manual (1/200, f20), ISO 100, no TTL (manual).
Anyone else seen something similar? Camera is at FW v1.3.1.
