1^st Post

I have a focus problem that has developed on my D500 in the last three weeks, inconsistent focus.
I put up a test chart mounted the camera on a tripod, mirror lockup, focused took a shot, defocused, took another shot.
Out of 10 shots three sharp, three softish four oof.
I cleaned the AF sensor but no difference.
Any idea before it's off to Nikon?
My lens works fine on another body.

Have you tested the lens on another Nikon body?
I think that it could be a lens problem or a camera problem. Difficult to know without the same item test in a different combo of lens/camera.

Sounds like you need to get the camera checked out.

My lens works fine on another body. Have you cleaned the connectors contacts/pins on camera body and lens?

Is it the same problem in different focus modes? I assume it hasn't slipped into AF-A?

Never found what caused the focus problem, I did another reset on it and all seems fine now.
Don't you just love electronics. o.O

No! Ive found quite frequently it's the sequence in which you do things that's important. So maybe redoing the reset after everything you tried fixed it? I wondered if reinstalling the firmware might have been an option....but hopefully doesn't matter now.

Glad it is working properly again.
