So glad I've most of my lenses are old enough not to be burdened by VR. Still wondering under what condition VR would help. I can handhold a 200mm lens, full frame, at 1/8 second and be tack sharp. Way back when it was a necessary evil to shoot that way, because legit theaters were not always bright and the film speed, Acufine and Diafine aside, was limited to ISO 400.
In these digital days there is little penalty to raise ISO to stratospheric levels, allowing dark scenes to be shot much faster than 1/8th second. So, with ISO raising the roof, skill level with the camera is commensurately lowered.
The lightness of modern cameras is a big issue, I suppose, as the cameras do not "settle" as well in a photographer's hands. The weight of former pro film cameras was something pros counted on for better imaging.
Facing grab shots in restricted spaces afforded no tripod setups, and so, shooting with slower transparency film, like Fuji 50, necessitated steady hands with braced elbows for 2 second exposures like the one picture here.

I was told that when the camera is on, the sensor is positively charged and that attracts dust. I don't know if it's true, but I try to turn the camera off when changing lenses just in case.
This thread induced me to get out the Canon instruction manual for my 60D and read what it said about this subject. To my considerable surprise it says nothing whatsoever about turning off the camera when changing either lenses or batteries. It does say to turn it off when removing the SD card, but doesn't mention it for installing the card. I may have missed something but I did try to look in all the relevant sections of the manual. Very surprising!

Or changing the SD card. Any electronic component can short if moved near another conductive material while a charge is applied. It is very unlikely to happen with the camera parts but why take a chance that can require time and money to fix.

VR will let you hand hold the 200mm lens at 1/2 intead of 1/8.

Doing such (leaving the camera turned on when changing a lens) would be like changing a fan belt on an automobile engine and the engine remain running.
I don't
think so!!! Nothing about a camera has the potential to take your hand off at the wrist. An illogical analogy calls the rest of your comments into question.
I always turn the camera off when changing lenses, cards or batteries

Manufacturers should have built in a power-switch override in the lens locking button. When that button is pressed, the camera would automatically power-off!
That would just make too much sense for them to do it.

Looks like you haven't been here long enough to find out. We've seen your sort before - they're in the attic.

Now that we know, many of us might not either. I had been missing the warning given in fine print so far! Manuals should indicate this in
bold print prominently! Does make sense, particularly when weather turns cold and dry and it is static-city all around!

I attempt to remember to "power down" my camera before changing lenses, CF cards, batteries, flashes, etc. Can't say I'm perfect at this, but I do try. Thats what every camera manual I've ever read says to do! So far I've been lucky, but one never knows! Upon occasion, I'll find a camera still on at the beginning of the shoot on the following day. For this reason, I also (USUALLY) carry a spare, sometimes fully charged, battery. I have heard from many that they believe it doesn't matter, but I've never been a daring fella.
I read that the focal plane is statically charged (positive or negative?) while the camera is turned on. If so, leaving the camera on while changing lenses increases the probability of getting dust on the focal plane. Removing the SD card while the camera is on shouldn't be a problem if the camera has finished writing from the buffer to the SD card. Inserting an SD card shouldn't be a problem either.

What is the problem with turning cameras on and off?

A Friend of my wife's (and me) had their house hit when the High Voltage lines fell into the secondary, lower voltage lines, which came to their home. (Northridge Earthquake, 1994)
The resulting surge blew their main panel to smithereens, and anything plugged in in the house also got the brunt of the surge.
It all got fixed, repaired, corrected.
But to this day, my wife unplugs anything not on.
Try putting your bread in the toaster and waiting... and waiting... and waiting... and the damned thing doesn't pop because, guess what?
It's unplugged! :evil:
But hey, 3 TV's and boxes are plugged in because they take too long to start up if you unplug them.
Makes perfect sense. To somebody....
(And no, I don't use an electric coffee maker. I use a gas stove to boil water, and a French Press. I'm weird like that.) :P

Yipes ! That's more than a spike. And I've also waited for the toast.
:D
I am now wondering it not 'turning off' may be the reason that I cannot find images on the SD card that I was positive I took?
Thanks for the story. V
Turning camera off when changing anything connected to its circuits should be standard practice and this goes double in winter when static buildup can destroy internal circuitry.
