p.1 #1 · VR seize to operate in vertical position on 300VR
Hi all
I just purchased a used 300VR from a reputable dealer. Great optics, but when testing it today I noticed VR shut of when turning the camera in vertical position. Signs of a defective VR-unit? Vr stop to function also when I put the camera back to horizontal shooting position. It works again If I turn off the camera and back on again.

Perhaps try switching VR mode to "Active?"
Somebody keep me honest here, but I seem to remember reading somewhere that VR in normal mode only compensates for movement on the vertical plane - which could be a problem if the body was rotated into a portrait orientation. Active mode provides compensation on both the vertical and horizontal axis.

Your lens is probably fine.
VR works when there is some detectable vibration, but switches off if there is extreme vibration (because the AF points in the camera cannot continue to measure the amount of vibration at the target) whilst VR is running.
I would describe turning the camera whilst VR is running from horizontal to vertical or vice versa as the equivalent of extreme vibration.
If VR keeps running when you do not flip the camera 90 degrees it is working as Nikon intend.

Kjetil - I'll test this on my lens when I get home. Send me a PM tomorrow if you don't hear back.

Thanks guys. With my 500VR this is no problem. VR functions just as it should. There is also a 'clunk' noise from the Vr sometimes. Also one out of three times the VR will not engage if I start to shoot in vertical position (i.e holds the camera completely still, not flipping it)

I don't have a 300VR but something doesn't sound right here. On my lesser 70-300 VRII, the VR works equally well in landscape and portrait mode. I have shot hundreds of my son playing football in vertical position and the VR never failed.
Normal vs. Active does not apply here. Active is when you and the subject are in motion.
Note that your 500VR works fine in either position. Unless the 300 has a different VR system, something is amiss. Also, you need a "reset" by turning the camera on/off after going from vertical to horizontal? Definitely not right. I would bring it back for an exchange.

What does AF have to do with it? The pitch/yaw sensors in the lens determine the amount of compensatory movement required by the VR motors. It appears that the lens has a defect.
