This happened to me for the first (and so far only) time 2 days ago.
K-3 Serial number: 4828535. Pre-ordered and then one of the first delivered in the UK last November. Firmware
1.03.
Situation: K-3 & D-BG5 battery grip. Each with Ricoh/Pentax LI-190 batteries, which had been well-used that day and probably less than half capacity each left.
Shooting in burst mode (HI), TAv, SR on, AF-C (SEL 2).
Sandisk Extreme Pro 32 GB cards, one in each slot. DNGs, in "Sequential Use" mode.
DA* 60-250mm f/4. I was probably using the new 1.4x Teleconverter at the time.
I switched the camera off, and after a short time the effect stopped. Then I switched back on and continued.
Cool but not very cold day.
