Do you turn the camera OFF when changing a lens?

    The manual says you should turn the camera OFF before removing or attaching a lens to the body. A quick google search says that many folks do not.

    I'm curious if there is anyone that leave the camera ON while switching lenses and if they ever ran into any problems?

    Yes - I turn the camera off when switching lenses.

    As per instructed. No need to damage the equipment. It is a good practice to follow the manufacturer's instructions.

    Most of the time, but when I haven't it hasn't hurt my camera, I hope

    Always, why would you not? (changing lens is a rarity for me though)

    For faster changing of lenses if/when needed. I'm so forgetful that it's also one less thing I need to remember to do. :)

    When I'm in a rush I don't turn it off sometimes and haven't had any problems.

    The only time it causes issues is occasionally when using manual glass the exposure gets out of wack (wayyyyyyy over-exposed) and won't return to normal until the camera is turned off and then turned back on...

    You want to turn off the camera because while it's on, there is electric current running on the sensor which attracts dust particles more easily

    The guy above me said it first...

    Leaving the power on doesnt hurt the camera in any form, but when it's left on it will attract dust like metal to magnets.

    Plus, the cleaning works on power up, so if something gets in there it will be shaken off

    Yeah, changing lenses with the power off is a dust prevention issue. Holding the camera pointed downwards also helps. As for me, I don't really bother. I swap lenses with the power on, left for long periods pointed up, whatever. The SSWF dust buster has always kept it clean for me. Of course, if I'm in an extreme dusty place I will be more careful.

    I rarely, (if ever), turn the power off when changing lenses. Always in a rush. Gotta stop and smell the roses, turn off the camera then change a lens or two.

    From the E-P2 manual:

    Maybe you should have a closer look at your camera's sensor Ned, SSWF only works when the camera is switched on.
