There may not be any communication on the data bus, but if you take a look at the Canon EOS pinout I posted above, you’ll note that battery voltage is present on pin 1. Now whether that is active any time the power switch is on or just when you depress the shutter is unknown (but I’m going to go measure my 5D3 without the lens and see), and I have not looked up the pinout on the Nikon interface. I do take your point that the AF motor or aperture control isn’t activated unless you press the shutter button first.

This has gotten a little testy. Who would have thought? I wonder if anyone here has ever heard of anyone trashing their camera by changing the lens with the power on? Anyone, anytime, ever? I deal with lots of photographer, professional and amateur and in twenty years of digital (and thirty of film) I have never heard of this as any sort of problem. I did some broad searches on line for people having this problem and came up with nothing? Not one mention of this. So, do what you're comfortable with but realize this is a bogus problem and you will never have any trouble by doing this....Cam

Hello all,
I was just wondering if it's necessary or even a good idea to turn off your dslr camera when switching lenses? I've read a bunch of articles and some say yes, others say no. I always do because I'm not sure if it does harm to the electronics in the camera if left on. Tia for any feedback.

Not testy on my part (and I am dropping out after this post), BUT your statement: ...“realize this is a bogus problem and you will NEVER have any trouble by doing this” I think is an irresponsible statement/advice. You cannot possibly make this blanket statement accurately for all possible cameras. In fact, this directly from page 61 of the Nikon D750 manual (and it’s the first manual I’ve checked other than my own):
“Be sure the camera is off when removing or exchanging lenses. To remove the lens, press and hold the lens release button (q) while turning the lens clockwise (w). After removing the lens, replace the lens caps and camera body cap.”

I have a question. After six pages of discussing whether or not a switch should be on or off, who has changed their position on the subject?

People of this age group generally never change their position on something. Their objective is to prove they are correct and any contrary opinion is simply that, just an opinion and not fact.
As I and others have said, we've changed lenses with the power switch in the on position to no I'll effect. If anyone wants to turn their camera off, feel absolutely free to do so.
