How do you use the main "on and off" button? Ok I'm guilty of using a silly title to get your attention. But, seriously, how do you use the on and off button? I go to a photo shoot...

Ok I'm guilty of using a silly title to get your attention. But, seriously, how do you use the on and off button? I go to a photo shoot with the button in the off position. I see a shot and turn my camera on. I take a picture or two and then turn the camera off. I got thinking about this the other day. Why turn the camera off? I have three batteries that I use in strict rotation. I am thinking that turning the camera on and off puts more wear on the on and off button. The on and off surge of power might use more battery power than if I left the camera on and let it go into sleep mode. Do any of you nice "Hogs" have an opinion on this subject?

You don't turn your computer off after you have read two or three emails, do you?

Same applies to your camera, in my opinion.

I leave mine on from the time I start shooting till I tear down and pack up.

I always leave mine on when using it, slight chance that I
may miss a shot or two, even on off the camera still drains
the batteries.

Leave mine on while shooting all day. Turn camera off to change lens or extend periods of inactivity like lunch.

I keep my camera on when out and about with it and have even been known to pack it away with the power on.

Thanks for your input all you nice "Hogs" out there. I am glad that you backed up my decision to leave my camera on from now on. And yes I do leave my computer on all the time, grusum.

I buy a camera and turn it on to Full on.
It's NEVER turned off again till I sell it! ;-)

I don't know how true this is but I've heard that leaving the camera "on" leaves a slight charge on the sensor. As a result, if you're changing lenses without protecting the opening, dust can be attracted to the sensor more so than if the camera is turned off.
Just saying,,,,

It's very true that the sensor's a dust magnet, when its charged up.

Does ANYBODY ever consult their manual before just blurting out a question?

No doubt that is probably a novel question to many, but you may just learn some things. :hunf:

I'd like to see some sort of technical paper from those that are buying into that.
Let's not forget that the shutter is in front of the sensor as is the AA filter on most cameras AND a protective cover behind that!
The sensor if it has a charge is NOT a junkyard magnet.
If the sensor has a charge the dust has to have the opposite charge.
Are silica particles inert? What exactly IS dust that it will take a charge.
Is earth a conductor or a non-conductor?? Just asking. ;-)

I turn off my Cannon when I am not using it...turning back on for the next interesting shot...simply to save my battery life.
