While out in the mountains trying to make my batteries last as long as possible I often wonder when to turn a 5D2 battery off between shots -- as opposed to leaving it on and letting it go into sleep mode.
There is at least one time threshold where a 5D2 uses less energy to turn the system off between shots. Is it 30 seconds, 2 minutes, 10 minutes, 30 minutes ?
I asked Chuck Westfall a couple years ago – with no answer yet.
We could figure it out if we knew how much energy (say in micro-watt-hours) a 5D2 burns per minute between shots –
1) With all LCD Menus off,
2) With all LCD Menus on,
And how much energy it burns to turn a 5D2 on, and how much energy it takes to turn a 5D2 off (with Dust-shake on and off).
