I've reduced the sleep timeouts to minimum... So I shoot, and carry on... Camera goes to sleep. I want to shoot again, I half press shutter, it wakes up... Rinse... Repeat
That is pretty much same I ever did with my DSLRs except the minimize the timeouts part
When I know I won't be shooting for some time (camera going into bag, dry box or taking a break etc), I bother to flip the on-off switch. Though, because it being a flip/mechanical switch, I prefer it less
Just like half press shutter can do instant wake, is there a way to do instant sleep? Through a button press somewhere?
