Do you ever switch your camera off?

Do those of you with a 30D or similar ever find it necessary to switch you camers off? With the camera automatically switching off after a couple of minutes (or whatever you set it to in the custom settings), do you find it easier to leave it on all the time, ready for action?

I always turn it off when putting the camera away (in my backpack). Even though the camera turns off automatically, it will quickly become active when the shutter button is pressed. And with a grip on, that can easily happen even with it in the camera bag. So, to keep from draining my batteries unexpectedly, I switch the camera off.

I leave mine on all the time unless I'm storing it away in the camera bag.

I Always turn it off.

I always turn it off. I want to avoid swapping lenses and without realizing that the camera has turned itself on and magnetized the sensor...

I've often heard this said, but surely the sensor is behind the shutter curtain, which is shut...???

I think it's staticly charged, but don't want to be picky

Right or wrong, I always turn mine off when swapping lenses. I also turn it off when I know I'm not going to be using it for a while, although I'm re-thinking that. It's an old habit that came from the days when I had a Nikon N990 that would eat batteries for breakfast.

I turn mine off when not using it. Like when packed away. The XTi turns on right quick and is ready to shoot almost immediately.

I leave mine on at all times with the auto-off set at a minute or whatever while it's out of the bag but if I'm not going to be using it for a little while or it's going back in the bag it goes off.

Static is prolly right.

Regardless, if my camera is on when a lens is removed it functions as a dust "magnet".

Yeah - I switch mine off.

when putting the cam away i turn it off obviously. And also if im walking about i also turn it off... old habit i guess. The same goes for the xt.

Take a look here at what Chuck Westfall, Director of Media & Customer Relationship, Canon USA, had to say about your "dust magnet" theory:

http://www.digitaljour​nalist.org/issue0607/t​ech-tips.html

Below is an excerpt from that page. The paragraph in bold is a question to Chuck Westfall with his response underneath that.

I'm curious if switching lenses while the camera is still on has any potential downsides, other than the obvious loss of everything in the buffer. I'm particularly concerned whether leaving the camera on increases the likelihood that dust might be attracted into the camera, or if there are any detrimental effects on image stabilized lenses. I'd also appreciate any additional insight you can provide on why leaving the camera turned on might be a bad idea, or why it really doesn't matter.

I'm not sure where you got the idea that switching lenses would clear an EOS digital SLR's buffer memory while the camera is writing to a memory card, because it doesn't. On your second question, it's always possible for dust to enter the camera when changing lenses, but whether the camera is on or off during this operation makes no difference. On your third question, no detrimental effects are caused by changing an image stabilizer lens while the camera is on. I've covered the pros and cons of leaving an EOS digital SLR switched on in terms of power consumption in the September 2005 column of Tech Tips, available here:

Other than these issues, the main concern about leaving a camera turned on is the possibility of unintentional shutter release that may occur if the equipment is stored in a gadget bag or other location where the shutter button might be pressed inadvertently.

Maybe its just my imagination or coincidence, but my own anecdotal experience is exactly the opposite.
