My Nikon D50 will not focus. I push the shutter 1/2 way

Customer Question

My Nikon D50 will not focus. I push the shutter 1/2 way down--and it just zooms in and out and will not stop at the focused point. Will not take a picture.

First, try a hard reset, to set a good reference point, using the instructions attached.

Then, detach and reattach the lens, clean the contacts on both lenses and camera body where the lens is mounted with an eraser. Be careful to not allow residue to drop into the camera body. Bad communication between the lens and the camera can also cause of this error.

Finally, the one most likely thing that even experienced photographers miss is that a single small spot or smudge on the lens can cause the problem that you are having. Carefully clean the lens and look for any scratches.

Please keep in mind that my diagnosis & solutions provided are directly dependent on the accuracy of your description of the problem. As with any "do it yourself" fixes, success is a "team effort", since I can't see or touch the camera, and relies on the customer's manual dexterity and ability to follow the instructions well. If the "do it yourself" approach doesn't work out for you and you need conventional repair, please let me know.

My camera just took a picture but the auto focus---in and out is still not working.

I want the auto focus and automatic hold to take the picture to be working and it is not. Also--how do I get the clear picture in my review finder---instead of all that data overriding the pic?

First, do you have another lens to try. This will eliminate a lens flaw and point to the camera as the cause of the problem. Please let me know if you do.

Next, to clear the display of unwanted information press the multi-selector (shown in the attached photo) up or down to select the display configuration that you like.
