Even though my led screen is cracked on my NIKON DX 3100 can I still use it manually... It's not auto focusing and shutter is slow or it just releases once "clicks"

SOURCE: Nikon D40X stopped auto-focusing yesterday

I had the same problem. My issue was with all my lenses. I solved it by going to the menu and selecting the custom setting menu (pencil icon). Then from the right menu select the AE-L/AF-L and press OK. Then make sure it is set on AE/AF Lock. Presto...all my lenses worked on auto-focus.

Maje sure you lens it not set to manual focus and that the lens is mounted correctly. Also - FWIW - shoot with a fast shutter speed (1/250 or better) to avoid blur.

SOURCE: I have never been able to auto focus with my Nikon DX 18-70mm

Sure there's a cure! Auto focus on the 18-70 and a D70 has a few switches and menu settings that help to set it up. The switches are on the lens (I'm going to guess this is the one you're missing) and the side of the camera body. If you only have problems with this lens and other lenses auto focus fine, this is really the only thing that could make it not focus. The switch has two settings, M/A and M. It must be in M/A in order to auto focus. Older auto focus lenses don't have this switch.

The other switches and settings would result in auto focus not working with any lens you put on.

If you have problems with other lenses, or if the 18-70 is your only lens, drop a note here and I'll go into more detail on the other settings.

you should change the focus lock to AF-S, instead of AF-C

ensure camera is not in macro mode.


I hope this was useful.
