Hi,
I've been reading through the manuals for my new 70-200 f/2.8 VR II nikon lens, and it suggests that I should turn VR off, and switch the camera off, when removing the lens.
It doesn't say why, nor what the repercussions are.
I've removed the lens with VR on, and the camera on..
I noticed this, and shielded my face in anticipation for either the camera or lens to blow up..
However, they both continued to work ..
Does anyone here have any experiences or suggestions as to why I should, and what would happen if I don't turn off the camera when changing lenses (or this lens in particular)? |

| I used to turn off the camera when I changed lenses as well. That was 5 years ago when I first used a DSLR. The last 3 years I have gotten away from that and have suffered no negative repercussions at all. Is Canon different in this respect from Nikon? I have no idea. Just my 2 cents worth. |

I turn it off for everything. Honestly I probably turn my camera on and off a hundred times a day. I was going to start a thread on how bad that was (?), but you've paved my path. no intention to hijack here.
To stay on point I never turn my VR off when removing the lens, though I'm a safety first type person so I will if I should. |

| I never turn mine off. I used to when I would change batteries, but now most of the time I forget then as well. I have suffered no ill effects from this. |

I turn my camera off to ensure the mirror is not in lock up position exposing my sensor to dust and elements of nature. It doesn't take that long to shut off, change lens, and power up again.

I turn my camera off when changing lenses. The theory is that an electrical charge exists on the sensor plate when the camera is powered "on". Turn the power off to reduce or eliminate the dust attracting characteristic of the electrically charged sensor. While I always try to change lenses in a low dust environment, it's not always possible. ANYTHING I can do to slow down the "dust magnet" Canon 5D is worth the effort. I usually clean my sensor every week during the dry/warm season. (pec pads and eclipse fluid with a right sized swab). In the winter, my cleaning interval is normally about every month.

| This is interesting. So say there'll be five minutes or so between shots. Do you turn your camera off? I turn it off after every shot, but I live in Germany so I also brush my teeth from standing pools of water and have recycled my tears. Should I leave it on? |

Austerity is a virtue!
I have my camera set to "auto power off' at 8 minutes. But, it only takes a touch of the shutter release button to bring back "on". And, power up is almost instantaneous. The whole concept is to conserve battery power enough to be able to shoot an entire day without worrying about low battery power. |

I too turn the camera off after every shot -- occasionally (apparently when I change lenses, as the case may be) I forget to turn it off..
Cleaning the sensor every week seems a bit extreme. I've had my D80 for over a year and have never had issues with sensor dust.
Similarly, my D90 showed no issues either.
Is the 5D susceptible to dust, more so than other cameras? |

Well, I change lenses a lot. And, I capture images nearly every day. Sometimes, I operate in harsh environments. And, I'm particular about dust spots on my images. 80% of my gallery sales are landscape images, which usually involve a small aperture setting, in order to gain a deep depth-of-field. Every dust spot on sensor or lens will show. I have no fear of cleaning my sensor. It usually takes me less than 15 minutes to do the entire sensor cleaning procedures. Removing dust spots from several images would take me more time than that.
Yes, the Canon 5D is a bit more susceptible to sensor dust. More recent camera models from Canon have a dust removing vibration feature, which engages at every start up. Although, there are times when the sensor cleaning requires a "wet" swab "aggressiveness".

| I am so awesome that I can leave my camera turned on all the time, and it never runs out of power. So that is not a consideration for me. To change lenses, I simply roundhouse-kick my camera bag. If dust dares to enter my camera, a quick Falcon-punch does the trick. I have no fear of sensor dust. The dust fears me. |

| I've never actually experienced any issues personally (so consider this hearsay), but I've heard several instances where not turning the camera off when switching lenses, particularly VR lenses, can cause weird problems--issues with focus, VR system not working properly and metering anomalies. Of course, I've also been told that these can be fixed simply by turning the camera off and then back on, so it's not a major problem. I've heard this from Nikon users, so don't know if it's the same with Canon and other brands...if it says to turn your camera off when switching lenses in the manual, then I guess it applies to your brand as well. |

I usually leave the camera on when switching lenses. It hasn't been a problem at all.
You'll hear people saying that the sensor will have a static charge when it's powered on, but realistically, the sensor is behind the shutter curtain, and with practice, the lens is off the camera for less than 10 seconds in most cases.
You'll have to clean the sensor periodically anyway, and I change lenses many times when I'm out shooting.

| no, but i do turn of auto focus on the lens. I read some where it can mess up the lens (well the ones I have) if you accidentally manually focus the lens with AF on... |

Everything you have said is true. But, the thing to consider is whether dust is somehow drawn into the mirror compartment due the static charge on the sensor. That is possible. I live in a very arid environment... a high elevation mountain desert... < 10" precip per year. We have low very low humidity, which exacerbates the dust in the air problem.
Yes, I know photographers who have NEVER cleaned the glass filter above their camera sensors. They show me their images and there are 12 dozen dust bunnies. I guess it doesn't bother some people. And some people are terrified by the thought of cleaning their sensors. Mike's Camera in Boulder charges $100 for a sensor cleaning. I guess some people are willing to part with money, rather than conduct simple housecleaning chores.
So, I am agreeing with you. It probably doesn't matter if the camera is left "on". As long as we clean our sensors periodically, the dust spot problem is not too serious.

Having recently loaned out my 50D, and having used a borrowed 5D and my 20D for a while, I can attest that the 5D is the worst dust magnet of the bunch, followed by the 20D, while the 50D is much better... I still clean my sensor about every 2-3 weeks.. Oh, and the 5D + the 100-400mm is a dust sucking nightmare.... :) |
