I have been having an ongoing problem that occurs randomly
with my D50 when using auto focus.  Both the focus locking and
shutter release button become disabled.  The buffer area in
the control panel indicates either R19 or R09 when this
happens.

I have restored the camera to factory defaults with settings
as follows:

ISO Control set to OFF
ISO Auto set to ON
AE Lock set to OFF
AE -F / AF - L set to AF
AF Assist set to ON
AF set to A (grayed out)
ISO set at 200
Mode Dial set to AUTO

Any help would be appreciated.  Thanks, Jim

Welcome to Nikonians,

First I would double check that the lens and camera body both have the lens in the AF mode.

Does the focus confirmation dot in the viewfinder turn on?

Have you reviewed your hand holding technique?

It is possible that the when you depress the shutter button, you shift the camera out of focus.

Are the subjects well lite?
Is there good contrast?
Is the focus target unobstructed by bars, tree trunks, tree limbs, etc.
Is the subject larger enough to be detected by the Auto Focus sensor?

I've used camera for several years on trips all over he world until this problem started. Focus light in viewfinder does NOT come on. Have tried different lenses and light conditions - still have problem. In fact, now camera does not auto focus at all despite trying different settings and conditions. Any ideas? Thanks, Jim

Hi James,

Welcome to Nikonians!
Sorry to hear of your problem.
You could try moving the AF switch on the camera back and fourth a few times just in case the contacts on the switch are oxidized.
If all of your lenses are AF-S type, try cleaning the electrical contacts on both the lens and the camera body. Also make sure that the electrical contacts on your lenses all project out the same distance. They are spring loaded and can get jammed in.
Good Luck and Enjoy your Nikons!

Best Regards,
Marty
