It is like sleep mode to conserve battery energy. Beware, you lose the ability to use Q setting. I freaked last night when I could not use it. Then I turned the camera off, then On and regain the use of the Q setting. You can increase the time.

Some people have reported problems after changing the lens with camera in "on" position - Now I don't know if it was alive or in sleep mode but when changing lenses or cards I'd recommend turning it off. Otherwise - I've left mine on for days while traveling with no problems.

The point is it's not a issue. Professionals don't turn the camera switch to off every time they change lenses.

When dealing with digital camera device it is always recommended to turn it off when changing lenses, batteries, memory flash cards, flashes and plug in a USB cable. Read your manual. Turning the camera off is a safety measurement.

I don't turn my T3i off while between shots, but I always turn it off when storing or changing the lense or card.
The manual also tells you that leaving it in "live view" too long can cause heat to build up and increase battery drain, especially in hot weather or while doing multiple long exposures or video. I've never had a problem with it, though.

I must certainly agree with you.

Yes yes yes. At least turn it off when changing mem cards, lenses, or batteries. I don't see why it's so hard to just turn it off every time you are finished for the day. It's great that they have a sleep function and usually don't run the battery down when accidently leaving it on. I've done this a few times by accident. I've also left it on and found the battery completely drained.

I found that my battery pack used up juice when I forgot to turn it off and the camera had been unused for a couple of days.

Actually, in today's world, no. Twenty years ago, yes.

In today's world, as soon as you open the battery compartment or the memory card department, the camera shuts itself off. It's instantaneous so you won't be able to time it, but it happens.

My 550D (T2i) has been on since the day I bought it (bought it in London which is why it's a 550D and not a T2i). That was in June 2010. It has something like 176,000 shutter activations on it, so the battery and memory card compartments have been open quite a few times with nary a problem.

No, your T3i does not automatically turn off ! It automatically goes to sleep. There is a major misconception about electronics being off because you cannot see the LCD screen, etc. Power is still being supplied by your battery to the circuitry of the camera, and ready to shoot as soon as you touch the shutter button or other buttons on the camera body. Given enough time, it will drain you battery, just as a cell phone, laptop, i-pad, tablet, etc. will do. As previously stated, you stand to zap some circuitry if you elect to change a lens as you may awaken the camera and have power on the lens contacts. The door on my 60D, if opened, kills power to the camera. I am not sure if the T3i does or not. Strongly suggest that you don't get it wet when it is asleep either. Nasty things happen.

When you open the battery compartment or the chip door Of a Canon, it shuts the power Off. Changing a lens with power on is common practice, and I cant find any warning about this in any of Canon's literature. i have Left power on my own cameras for weeks (inadvertently) with no bad effects.

One reason to leave the camera on and not use the on/off switch is because the switch is a mechanical device. When it fails, it's not inexpensive to replace. Having the camera put itself to sleep saves a lot of wear and tear on that mechanical switch.

There are loss of things stated in owner manuals for all types of products that are put there for CYA reasons. There are always idiots out there that will use products in some bizarre totally unothorodox way and companies try to contain this.

I know a guy with a T2i that leaves his on all the time, never heard it causing him any problems. Personally on my T3i, I use the switch, off when I'm done or when I'm switching lens.

I never turn off my T2i, unless I want to run the sensor clean cycle. It starts up extremely fast when I half press the shutter button. There is no noticable effect on the battery, either.

You can set up whether you have auto turn off enabled and the delay to turn off using the menus (see p 139 of the manual for the T2i).
