Hi there,
I noticed that I can't shoot video with my K-r longer than a few minutes. Same with Live View, though I don't use that regularly. I have the battery adaptor and use 4 AA Eneloops. I am discharging a set that I tested and so far have drained 1287mAh out of them, so they were at least half full. The battery type didn't make a difference set to Auto or Lithium. I also tried some Alcalines (Maxell brand, so probably not the best), and the same happened with them, no matter the battery type setting.
I was running v1.11 and upgraded to 1.13 with no changes in that behavior.
Any ideas here?
Thanks!
