Nikon 24-120mm F4 lens problem.

I tried to post this under "Lens Problem" but couldn't figure out how to do so.
I have the Nikon D750 with the 24-120mm F4 FX lens.
Submitted: 11/25/2017 00:27 PM by Web
Lately the camera (or lens) is emitting a growling (grinding) sound as the camera is turned on or off. The lens seems to work fine. Focus is working fine, as well as the zoom feature. The LCD displays indicate the aperture and shutter information correctly, but this grinding sound indicates something is wrong.
The noise is not present with other Nikon and Sigma lenses.
Can anyone advise regarding the problem?

Try turning off the lens VR and see if it makes a difference. If the noise quits, then the VR is the likely problem. If the noise persists then the lens AFS motor is likely the problem. Either way it sounds as if you are in for a repair to correct the issue.

Can't help you with why, but the D750 and 24-120mm are totally silent when I turn them on and off. There is some noise (not loud) when the vibration engages and turns off. Have you tried tuning on and off with VR off?

It would be a good idea to ask NikonUSA this question.

I read somewhere recently that when we're transporting a lens with VR that we should turn off the VR before turning off the camera otherwise the lens might be in a position that will be movable and physical shock might damage the VR mechanism.
Edie; LensRentals reported that finding.

Actually that is not entirely correct. The warning comes from Nikon directly, and many years ago. The VR does not need to be switched off. What the warning is about is to let the user know not to switch off the camera while the VR is ACTIVELY STABILIZING THE IMAGE. Once the VR has gone inactive via properly powering down through the program sequence there is no power going to it until the shutter is half pressed re-activating it. If the VR is active and not properly powered down it runs the risk of not properly docking the VR lens element allowing it to simply flop around and risk damage.

Mia culpa (kinda)
The aricle I came across wasn't from LensRentals directly and is 2 years old.

Ok, thanks for the responses. Here's a bit more I have discovered on my lens grinding noise problem.
Yes, I turned off the VR function on the lens and the grinding noise is still there. Yes, I also moved the 'Norm - Active switch to the Active position, and the noise is still there.
However, I note that the noise is not there at all (when camera is switched on and off) if the zoom ring is rotated to the 40mm position and higher zoom.
To repeat my earlier post, the grinding noise is not there when I attach my Sigma DG (FX) 28-200mm 3.5-5.6 AF lens, or my Sigma 10-24mm lens. Neither is it there when I attach my Nikon DX 10-24MM AF-S 3.5-4.5G lens. It is only present with the Nikon 24-120mm 1:4G lens, and then only when the zoom is less than about 40mm.
Don't know if I have a camera problem or a lens problem.
Appreciate you comments.

Its clearly a lens problem. Next step is to try it on another body and see if it has the same problem. My bet is that it will.

That would be a lens problem. The 24-120 f4 has an internal motor. since this is a grinding noise something most be moving, and of course what ever is moving is being driven by that internal motor.

Yep, agree that this ol' 24-120mm lens needs a doctor. So got on-line with Mr. Nikon and shipped it off to L.A. I'll post an update if they tell me what the problem is.
Thanks for he comments.

Long overdue update on my 24-120mm F:4 lens problem. Well, Mr. Nikon fixed my lens for $156. Said it wasn't covered under the warranty, which greatly disappointed me, but I paid and got my lens back. They said they replaced the motor in the lens. One never knows though.
Thanks for all the responses.

I rejected Nikon's offer to repair the lens and opted to purchase a new one for an additional $423.32 plus $156 cost of repair to trade-in lens.

Final Post here: Received the new 24-120mm F4 lens but had already decided to buy the 28-300mm. So, will decide if I keep or sell the new 24-120mm. Yikes, this hobby is wrecking my allowance.
