How long do you leave your camera on?

- The lens power pins are always on, whether the switch is turned on or off.
- When you open the CF door it cuts the power, so no reason to touch the switch.
- When you open the battery door it cuts the power, no need to touch the switch.

Only reason for the switch is to disable the buttons and give you a free sensor clean.

Yeah I don't turn mine off unless I remember... I think I've gone weeks with my 7d being turned on at a time... lens changes? card changes, battery changes... switch stays on..

Meh.

there is a power switch?? Wow, Learn something every day. but seriously, I only turn it off to clean the sensor every so often. Battery hardly ever drains, even after a week or 2.

It's never off.

Mine doesn't ever see the off position except when changing batteries or cards.

I'm quite surprised by the replies in here.

On my 7D, cycling the on-off cleans the sensor. So if I've been changing lenses a lot, it's the easiest way to give it the ol' vibro-clean routine.

And going through the menus can also result in a broken switch...so what's the worry there?

PLUS I shoot concerts, so the power goes off in the intervals just in case some naughty fingers touch my cameras (usually on tripods) and erase everything!!!!!

I just leave mine on Auto 1min.

Like I said, when I change cards or batteries it gets turned off. I don't need to clean the sensor any more often than that.

I only turn it off when I come in from the cold to a warm house so that its powered off if any condensation forms.

Wise precaution on the condensation. Even wiser would be to take the battery out if you think condensation will be an issue - same reason to take it out if the camera gets dunked, even in the "off" position.

That's a bit paranoid and overly cautious imho. For starters, powering it off doesn't remove the current. You would need to remove the battery and any axillary batteries. You would also need to remove the lens as there is still current between the lens and the body. That level of condensation is nearly impossible to achieve unless it was really cold and the house very hot and humid. I live in Bangkok where it hits 41c and have went from AC (24c) to out outside (and vice versa) and have never seen condensation.

I think Chuck Westfall had a write up a while back about sleep mode stating it was pretty close to powering it off from a consumption perspective.

For me, I turn it on when leaving for a shoot or walking around. Once I'm done for the night (shooting, post processing, etc..) I shut it back off. I'm not worried about a switch or anything, just saving a bit of battery life. The sensor cleaning is a bit of a plus too, but not really a concern.

I'm used to turning it off every time I stop shooting, probably from good gun habits, the 1d2 power switch looks and feels like a safety, so I just subconsciously turn it off when im not 'shooting' ha.

Mine is always off when it is in the bag or if I know that I will not be shooting for a day or so.

I once went from a very dry, close to freezing condition to an aviary that was both humid and around 32C like tropical rainforest environment for the birds. Took my 300 2.8 over 15 minutes to dry off enough to take clear pictures as it warmed up. I had the camera itself in a plastic bag as it warmed up - didn't want to take any chances.

wow, that's pretty intense AJSJones.

ps...your avatar scares me

I did get some nice pictures though!

Looks like I'm in the minority here. I turn it off pretty much everytime I stop shooting. So several times a day when I use my camera. I always knew in the back of my mind that it auto powers off, but I never really stopped to think about it. Just habit I guess.
