You're welcome. Fwiw, I came to the same conclusion: the only "longer than 30s" setting is the interval when using the built-in intervalometer. The manual, iirc, highly recommends using the AC adapter when using the intervalometer.
Batteries -- completely unacceptable performance, but I am known to meow on occasion. After getting much less than an hour, and fewer than 30 pictures per battery, I have reverted to all the "eco" settings. I now get a little over an hour per battery, walking around taking pictures. The battery gauge on the LCD is close to useless. It shows the battery full for a while, then very quickly moves through 2/3rd, 1/3rd, 0/3rds, brick. The camera should ship with six batteries, the strap should hold them all, and the the charger should charge them simultaneously. Or, of course, the camera could include a battery selected to match the power requirements of the camera.
It's a remarkable engineering failure from a company that makes its living selling highly engineered products.
- Quick Preview: 2s
- LCD OFF: 10s
- Power Off: 5 min.
And I ordered this double-battery pack with car and wall charger
. NB: I don't have it and can't recommend it until I use it.
