Do I have to switch the D800 off when changing lenses?
With all kind of lenses or is there a difference in doing so between G- CPU- and non CPU lenses; SWM driven or mechanically driven (by the camera's AF motor) lenses ?

I believe in the manual(s) it says to never change lenses with the camera turned on.

I believe the manual, and turn off the camera before changing lenses . Sometimes I have forgotten to turn off the camera, with no ill effects. However, I think it is better to adhere to the manual.

I beleive it also helps to reduces risk of dust on sensor as there is no electrical charge

Welcome to Nikonians.
I always turn the D800 off when swapping lenses. Doesn't matter what lens I am changing.

Turning the camera off is the best practice. I'm sure we have all inadvertently forgotten to at one time or another. I don't lose sleep when I forget to, but I avoid leaving the camera on.

The only problem with leaving the camera turned on is that the sensor is still 'charged'. It's an electrical charge, much like static electricity that will attract dust. Turning it off is the better choice, for any lens change (or simply just taking the lens off), but as Scott says, I wouldn't lose sleep over it. I also try to keep the camera's lens mount facing down when I change lenses (camera turned on OR off), again just to keep the amount of dust to a minimum.

I once did a photo-shoot in an industrial metal recycling plant.... very small metallic dust in the air. It was so bad, I had to literally walk out of the plant to change lenses.

Much ado about nothing in my opinion. I've not worried about turning off any SLR ever. Back to the early 80s. Never an issue.

That whole "sensor is charged" is a strawman argument. I believe people get more dust in their cameras from using zoom lenses than they do from changing lenses. Darn few lenses are dust sealed.

I think I've read somewhere that changing lenses with VR could cause some damage or "strange things" could happen. I think that was something I read at Thom Hogan’s web bythom.com. I guess it's a good rule to switch off the camera. It's easy to accidentally engage the autofocus and VR with the camera on.

Indeed, the recommendation of turning the camera off first has been around long before digital. I thought it had more to do with the possibility of causing a short which may affect the electronics.

Anyhow I think it's a wise move. Besides what's the drama with doing it?

No drama. People are free to do as they choose. For me personally, if I am changing lenses in the field, it means that I am already behind and losing shots. So I'm in a hurry. I'd rather bring along another body in most cases than change lenses. Sometimes working with three bodies is a PITA though.

My most common config is a 300/2.8 on one body with a 70-200 on a second body. I store the 24-70 until needed. If I have help, I'll put that 24-70 on a third body.

It's certainly true that removing a lens while the camera is turned on and VR is still active is likely to cause a problem.

Apart from that, as others have said it's a good idea to turn the camera off when changing lenses. I always try to do so, but on the odd occasion when it's not been possible (or I just forgot...) nothing bad happened

Hi Philippe,

Welcome to Nikonians!

As stated above, the best practice is to turn the camera Off before changing lenses.

All AF lenses have a CPU.
The AF drive would make no difference.

It is my understanding that shutting off the camera just locks all controls. Therefore, changing the lens while the camera is on is not in itself a problem. It is just that you risk, by pressing something inadvertently, to send an electrical signal through improperly aligned contacts.

Hi Oivind,

If the lens is removed with the camera On before VR turns Off the VR mechanism won't lock so the lens element could move on its own. I suspect this would make it more susceptible to vibration or impact damage. Keep in mind that the VR mechanism was designed to lock when not in use.

Marty

I try to remember to turn the camera off but I suspect 70% of the time I do not. I've done that since the D70 days, and I change lenses a LOT when I'm shooting. I've never had it do one single thing unusual due to leaving the power on.

My suggestion: power off. But don't obsess about it.

I have never shut-off the camera while changing lenses with VR, OS, IS on at all times. Most of my lenses are VR, OS, IS.
Never a single problem and I have done it thousands of times.
As another poster here pointed out that more dust gets in from zoom lenses than from charged CMOS. Plus before you put rear cap on dust gets in the lens on the rear element and then due to turbulence of mirror that dust gets on everything.
And I know that as soon as you disconnect the lens electrical contacts become inactive. It is build in to every camera otherwise every one would have problems. Just think about it, if you clean the camera's sensor you need to remove the lens while camera is on. Right?

I think most camera companies recommend it though many people don't because they don't think it makes any difference.

Probably the main reason would be that an active sensor would attract dust but it's covered anyway.

I switch mine off mostly out of habit, but once in awhile I'll forget and it hasn't done anything really bad to the camera yet.

Not necessarily - when cleaning the sensor I normally remove the lens and then turn the camera on.

Aren't you the guy who's always complaining that your Nikon equipment is screwed up and you had to take it in for repair?

My suggestion is to try to remember to turn the camera off before changing lenses, as it minimizes the potential for a problem, whether it is dust, screwing up the VR or some other electrical glitch. Keep in mind that your DSLR is an electrical device, not a mechanical/optical one.

Forgetting occasionally probably won't kill the camera, but why purposefully do take the chance. As you can tell from reading this thread, most people feel that turning it off is the right thing to do.

Do you think that manufacturers don't know that people change lenses without turning off the camera and somehow protected their cameras against electrical failure? For example VR disconnects very quick as soon as you push lens release and before you dismount the lens.
Since majority of my lenses are with OS, VR, IS and I never had any problems (I will probably have them now because you probably jinxed it ) not even once, do you think it is a good indicator that there isn't one? Plus I have never read about it.
Otherwise they would have lots of cameras going back and forth for repairs.

I feel like buying a lottery ticket twice a week and for sure winning but reality is such that I forget to stop at the store to buy it

So reality is not always the same as feeling.
Like I said I have done it thousands of times and not a single problem.

If the camera is turned on and VR is still active, pressing the lens release button will NOT turn VR off. The button has a purely mechanical effect of releasing the lens lock.

I don't know whether it is possible to short the lens and/or camera while changing lenses but I switch the camera off regardless, enabling sensor cleaning automatically.

My procedure is to switch the camera off, point the camera sensor downwards towards the ground, remove the old lens, fit the new lens, then switch the camera back on.

Switching the camera on will automatically clean the sensor on a D800 if you have this option checked in your menu. If time permits, I also use a blower tool to remove any dust off of the rear glass of the new lens before it is fitted to the camera.

The posters are referring to the procedure to lock up the mirror for manual cleaning with a swab or other device, rather than the cleaning function build into the camera.

Yet you've reported quite a number of problems with your gear over the past year or so I think. I'm wondering if lens changes without first turning off the camera might have contributed to or caused some issues for you.

>As another poster here pointed out that more dust gets in from
>zoom lenses than from charged CMOS.

Perrone expressed an opinion of his. He never declared it as proven fact because it is not. Some people who note excessive dust on their camera sensors take upwards of a couple of minutes to change lenses, but later declare that they always change lenses quickly because that's their perception. Dust can get in during long lens changes. I've seen people purse their lips and blow dust from around a open lens mount on the camera and then afterwards state absolutely that they would never do such a thing because they simply did it without thinking about it much less remembering afterward that they'd done it.

>And I know that as soon as you disconnect the lens electrical
>contacts become inactive. It is build in to every camera
>otherwise every one would have problems.

Somebody might want to actually put a meter on the body mount lens contacts to confirm that. Declaring it as fact without some sort of actual proof might be a bit imprudent.

>Just think about it,
>if you clean the camera's sensor you need to remove the lens
>while camera is on. Right?

Wrong. Turn camera off. Remove lens. Turn camera on. Lock up mirror for cleaning. Remount lens when finished cleaning. Turn off camera.

Not if you are inadvertently touching the shutter release (or AF-ON button)

I don't understand your insistence on this point - it takes just a moment to switch the camera off, so why not just be safe?

As others have mentioned, it's not as if you have never encountered an odd problem with your equipment...

Regardless what people say or speculate the fact that dust gets through the zoom lenses quicker (even primes but slower) in to the camera is a well known fact that people know for as long as interchangeable lenses been around.
Take a look at your own lenses. There is dust in them. Mirror slap creates turbulence and dust migrates on your sensor and on the mirror and even on the prism. And if you have pump action lens it gets even worst.

I have done it the first way always. So it is not wrong.
It is just my choice.
In fact I could say that your way is wrong because while lens is off and you are flipping the mirror extra dust gets in. And I am sure you are not doing it in a class A room.

Lets see. Left hand finger pushing the release button. Right hand rotating the lens. The third hand growing out of my back touching the shutter

Because it is unimportant. What is important is not to think about it and change the lens as quickly as possible so I don't miss the shot.
Since I have done thousands of time and I have never, ever read about ill effects I would certainly say that turning camera off while changing lenses is trivial. If you feel better, go ahead and turn camera off. I certainly will not.

The problems I encountered related mostly to Nikon QC.

A reference for this (and your other assertions) would be useful. Otherwise, as Howard suggests, it's probably best not to make them.

Do you have a reference to show that changing lenses without turning camera off can hurt the camera or lens?
This matter is so trivial that I am not going to look for it. Besides, then you will claim that somebody is full of it too.
But I read about it years ago on one of the forums most likely on DPReview and that is why I mentioned it.
Think about it. Opening the card door shuts off many cameras, would you think releasing the lens would not disconnect something?
If this matter was so important it would be posted everywhere and it would be bigger than left point focusing problem, oil spots in D600 or light leak from top LCD on Canon 5D3. Yet there is nothing out there about this unimportant matter.

But that's not what we are saying - our point is that turning the camera off takes very little time and will completely remove any chances of electrical problems caused by clumsy changing of a lens.

Opening the card door does not cause ANY Nikon DSLR that I have used (9 different models at the last count) to shut off. And by the way, in the interests of experimentation, I did try pressing the lens release button on one of my D3s's while VR was active on the 70-200mm f/2.8G. VR kept running.

Maybe it's not posted everywhere because most people are sensible, do as advised, and turn the camera off first most of the time

D800 (English) manual (among other camera manuals), page 24. Step 1. "Turn the camera off." Nikon's instructions are good enough for me. The camera maker does not have to specify potential damage when providing such an instruction.

That's needlessly combative and insulting. Nobody in this thread deserves to be insulted by you.

I read lots of things in forums, now and in years past, including some of what you write. I discount the insistent stuff offered strictly as opinion without any support.

>Think about it. Opening the card door shuts off many cameras,

Opening the card door doesn't shut off my D7000 or my D800. Both camera are fully operational with the card doors open or closed. An open card door does not permit my Canon G1X to operate. Since this is Nikonians and a D800 forum, can we please just mainly reference the D800?

>would you think releasing the lens would not disconnect
>something?

When a photographer does not turn off the camera before mounting or dismounting a lens, the photographer is taking a chance that the safe mode designed into the camera's electronics to protect the camera from accidental lens connects/disconnects is going to work each and every time. The product manual states, in the instructions for mounting or changing a lens "Step 1. Turn off the camera." Advising Nikonians to disregard advice in the manual is a poor idea. Electrical and electronic systems often have safeties built in to protect the device from damage caused by common mistakes made by users. Many, many people get away with it for years. The most likely reason for Nikon to state "Step 1. Turn the camera off." in the manual as part of the lens change instructions is that it is the best practice. Advising otherwise is not a good idea unless you're prepared to take responsibility for damage to someone else's camera when they take your advice and then have a problem as a result.

>If this matter was so important it would be posted everywhere

The matter has been discussed repeatedly in a variety of forums over the years, and recently too, on Flickr, photo.net, DPReview, CambridgeInColor, byThom, LuminousLandscape, etc., etc., etc. It has been repeatedly discussed on Nikonians too. Why you think that such discussions might make it as big an issue or a bigger issue that any of the thousands of other questions or issues which are discussed on all the forums is a complete mystery. Do tell.

Thinking about it, turning camera off and then back on takes a lot of time.
At least a second or two longer longer and a lot of things can happen in one second.

But by the time you grab the lens to remove, it will stop.
Unless you are Speedy Gonzales
Besides it is trivial too.

Wrong, it is not posted because it is so trivial. And don't say "most people" because at least one poster here in this thread does not do it and the many others admitting forgetting about it.
Yet, no one ever mention any problems.

It is called Cover Our Assets.

What do you want them to say?
But since this is not a problem to me and thousands of other people
we don't have to follow that advice. But in case it does happen in the very, very, very rare case manufacturer is covered.

Also, I read in many manuals that manufacturer suggest to use only OEM lenses and accessories. And you know very well where this argument will end up.

Even though I did not mean to insult anyone and I don't know why you are taking it as insult can say that you are doing exactly the same thing. You are combating my and thousands people experience and actually insulting my and thousand people's intelligence.

Your insistence does not have any support either. Yet if there was a problem it would be reported somewhere but it is not so it is not a problem. It is only logical.

That is because in infinite Nikon wisdom they don't show it to you.
In fact when you turn camera off some of the functions are still functioning, just take a look at the top LCD.
My older NIKON D1 and D1x cameras turned completely off.

Discussing and reporting the actual problem is two totally different matters. You can speculate as much as you want but I have never heard of this problem and neither did you. So there is no point to argue about the problem that does not exist.

If I change a light bulb I turn the power off, remove the bulb, insert a new one and switch the power back on. Simple really, not rocket science. I call it "best practice"

One other poster doesn't contradict "most" in describing who does what. That's my opinion and also pretty good arithmetic.

In any event, Nikon recommends turning the camera off. You may not believe that it is necessary and they are just performing CYA, but if you fry something in your camera or lens and send it in for repair, Nikon could say it isn't covered under warranty because you did not follow that recommendation. With my $2,000 to $5,500 cameras and lenses up to $2,400, I prefer not to take the chance.

If you are making enough money shooting, or wealthy enough, that you can consider all of you equipment disposable, you may decide that the shot you got is worth the risk. Of course if that is the time your camera or lens decides to #### out, then it was a bad bet.

I agree switching off is probably best practice but I have no doubt the lens and camera designers knew that people will forget from time to time so if diligent they would have designed accordingly.

I did once have a problem with D70 or D200 and my 80-400D VR.... dismounted the lens while VR and metering was active and the camera froze up. I had to remove battery, replace it and then do a reset to factory defaults before it would work again. Subsequently with other lenses I occasionally forget and it has not caused any problems that I know of.

How about this for arithmetic?
It is called risk management.
There is a risk associated with all activities.
You can get hit by the lightning but chance of that happening is 1 in the millions. That is why we mostly are not afraid being in the rain.
Chance of getting in to an accident is very high and yet we drive everyday. Chance of winning a lottery is one in a billion but we buy lottery tickets anyway.
And so on and on and on......
And we read about this everyday in newspapers and magazines and on the web.
But I have done lens change myself thousands of times.
With many millions of cameras out there and billions of lens changes without turning camera off even by those people who always say they do it but not even one case reported my math says that odds ruining
the camera by not turning it off while changing lenses is less than winning the state lottery. Much less.



>In any event, Nikon recommends turning the camera off.
>
Nikon also recommends to use only Nikon lenses and accessories.
And if not and camera gets ruined it is also voids the warranty.
We have all seen bulged batteries and broken grips in the pictures posted here and elsewhere.
Yet, third party accessories is a booming business outselling OEM by a huge ratio judging by Amazon and Ebay sales. Even trusted stores like B&H and Adorama for example sell third party accessories and lenses.
Chances of using third party stuff is much, much higher than not turning camera off while changing lenses.

So how is that for a math?
