Hello, it's been a while since I've been around here, being busy with work and life lately. I've noticed a strange issue with my lens on my last few outings.

More and more often, the lens will stop focusing correctly when I've been using it and it's been working fine. I try to focus, and it just goes straight to max focus, then slams straight to minimum focus. If I hold the focus button or repress it, the lens just jumps back and forth between minimum and maximum and I can audibly hear it hit the stops on both ends. Oddly it seems to travel through the range much faster than if it was working properly and I set it to minimum distance and tried to AF on something in the far distance.

The problem usually disappears if I turn the camera off for a few seconds and then back on. Has anyone experienced similar, or have any recommendations? I'm trying to remember when/where I bought it to see if it had any warranty but I expect it's expired by now. Thanks in advance!
 
Have you updated the camera firmware since you bought the lens?

Both lens and camera (Nikon D500) were bought used; I checked them at the time and they were up to date.

So a recent camera update didn't affect the lens then ... there is a dock available for this lens IIRC which may allow you to default it or update its firmware.

I have the dock as well which I've used to calibrate the lens, I'll check for a new update or try resetting it. Thanks for the idea!
 
For the sake of anyone who may have this issue and come across this thread; using the TAP-in Console to perform a factory reset and then reload my calibration adjustments seems to have fixed the issue.

I only had a short period to get the lens out for a test between rain showers, but in that time it worked perfectly (whereas the last few outings it would have malfunctioned multiple times in the same time frame) so fingers crossed it's fixed! I'll put an update here if it goes wrong again.

Thanks Gramps for the idea.

Great news Luke, always good to recover from a problem ... and no extra cost either :)
