    Yes I do turn it off but don't see a problem except you may get more dust on the sensor.

    I think no difference if you on or off your camera since the mirror will be 'down' in front of the sensor unless you set mirror locked up while you on your camera.

    I don't know how true but I keep "hearing" from other people in many forum saying that with the power on, the sensor is electrically charged or something like that and it will attract dust. Enough people saying the same thing, it will eventually become the truth.

    dust is all around with or without the mirror flap.

    the reason why is cos there is some static charge whenever your cam is on, so by doing so, those dust nearby sensor will be sucked towards it.

    so i try to off my cam whenever i change lens.

    I think it's better to play safe and switch it off, it juz takes a flick of a button.
    Fyi, it is recommended to turn off ur camera especially if u're using IS/VR lenses.

    Doesn matter really. except the previous settings might still apply on the other lens like the aperture .. there was a few times in a huff i forgot to switch off.

    There was once when I did not switch off while changing lens and the camera "hanged" - the AF and shutter won't work no matter what I tried - even switching off & on repeatedly. It resolved only when I took out the battery and put back - something like a hard reset.

    I try to remind myself to do this... turn off the cam first, swap lens, in-camera sensor clean.

    Best to off power before changing lens, like bro sinned79 mentioned, dust around the interior of the camera might get attracted to the static charged sensor. No harm making this a habit

    Is there anything in your manual that states "Switch off before changing lenses"? If not, then all technicians and lawyers have made sure there is nothing to worry about. Worrying will only shorten your shooting fun.

    I'll turn power off in case I accidentally short those electrical contacts.

    It's better to be safe than sorry.

    Just remember to do it and it'll become second nature in time to come... afterall, you would turn the wall switch off before taking out the plug right? Its the same analogy for me, digital body & lenses are electronically connected so why not?
