| Can someone tell me why it is bad to swap a lens without turning off my DSLR? |

Who said it's bad? I do it all the time - never had a problem of any kind. I rarely if ever get dirt in my camera if that's your concern and never have had a fault - and that' with 70,000 shots or so. I've used a belt system at weddings and the lenses sit in the belt with no caps, I set them on tables or hte floor - no probs. Same for many other shooters I know.
Yeah, the sensor is 'charged', but it's behind the mirror.

| They say that a charged sensor attracts more dust. |

If there is any dust behind the mirror its heading straight to your sensor. Its not absolutely taboo terrible or anything. Just something to try to remember. They also say that leaving your camera on heats up your sensor slightly which causes noise so you should turn it off if its going to be awhile until the next shot. *shrug* I don't put a whole bunch of stock in that one either but I do it. It certainly doesn't hurt anything.

I am pretty sure that was only for cameras with a live lcd view, they have to keep the sensor powered the whole time.
What I want to know about is on the D300 removing and adding the compact flash card while on. I know it is a sin, but by mistake I removed and inserted one while the cam was on, and not only was the camera fine but it noticed the different card instantly. I do know the D300 always has the socket hot in order to read the number of frames remaining and if the card has been removed in order to display -E-.

I think it's safe to say that turning the camera off before changing lenses or memory cards is less likely to cause trouble (like dust on the sensor or data loss). And it's not that much extra work, right? So I try and do it properly each time, better safe than sorry.
The argument "I've always done it like this and nothing ever happened." is not very convincing when we discuss rare events with significant consequences. It reminds me of guys driving through villages at 120 mph and claiming "Hey, I don't have to respect the speed limit. I've always driven that fast and nothing ever happened." - until they run over a child. (Don't get me wrong, I'm not comparing dust on the sensor to a dead kid, it's more of a theoretical issue about the quality of an argument of that kind...) |

Well damn, I always use my right hand to insert my CF cards and I've never had a bent pin, but maybe I should be more careful anyway. ;)
Sorry just poking some fun, I have to think the D300 was designed for it, unlike the Canons that turn off when the card slot is open, or maybe Nikon was just lazy... |

Reading the list of responses from  badman's link, This is the response that seemed the most reasoned IMHO:

A lot of responses to read through before discovering that nobody has a definitive answer. This is a technical question, and an objective answer should exist (though that answer may be diferent for different bodies). Nikon instructs that the camera should be turned off. Is that to be considered an absolute or is it just a suggestion to minimize the possibility of a problem which may or may not occur? It's really impossible to know. Given that, I opt to turn my camera off. As it is said, "It couldn't hurt." ...
...I am sure that there are those who have "hot-swapped" their lenses with no apparent consequences. I'm not sure I want to use their experience as proof that Nikon is erring on the side of unnecessary caution. I had an uncle who smoked cigars every day and lived to be 97. Statistical anomalies don't answer the question. Hey, it takes a eye blink to do it. Call me a girly-man, but I spent too much on my bodies and lenses to just blow off Nikon's cautionary instruction.

| No where in my instruction manual is this written and I never ever shut down to switch lenses. I do for cards and batteries though. |

Well what I hate about turning off the camera is waiting for the lens to retract so I don't damage it, however I think I already did. I turn it off and the lens does not move, I have to turn this dial thing to force it to move. Do I need to have my camera serviced?
hehe, seriously though I will always try to turn off the camera first. However I am reminded of the Nikon owners guide for the D300 that says if you attempt to clean the sensor yourself even with just air that it will be destroyed or something to that effect. Seemed extremely paranoid to me. |
