It's just a thought. I would really like a way of putting the camera to sleep rather than waiting for it to sleep when walking around. I'm sure it would be an easy software / firmware modification. At the moment I switch to review as then it's not in live view all the time switching off is another option but then startup probably uses more battery than a sleep mode, plus the startup time is annoying.... Second issue is there a way is setting sensor cleaning to switch off as on four thirds cameras? Sorry if these are issues already raised ... If they are perhaps Olympus will hear!
