Nikon D100 stuck in Auto mode

Hello mehran_vafae, is supposed to have put a DX lens.
The mode dial, select in what way is going to take a picture.
You can make combinations according to the mode set in the mode dial, with the Fn key / command dial, command dial / aperture A mode, command dial / shutter speed S mode, Full Auto / + / - compensation sw, etc. ..
Please carefully read the user manual supplied with your camera and if it fails take them to Nikon service.
Regards

You can get the manual on the link below to find out how to put on auto mode.

Good Luck

Try this...clean the contacts on the camera body and the lens where they meet with a cotton swab lightly dampened with rubbing alcohol.

Inside the lens mount is the stop down lever. As you look at the camera, it is at 9 O'clock. Move it a couple of times up and down. It is probably stuck.

The mode dial (topside left) must be set to M. That's it for manual settings - the camera won't check anything, and certainly shouldn't require the flash. You need to choose your own shutter speed and aperture settings to get a good photo, but the camera will let you take a picture no matter how you have it set.

I had similar problem with D80 try removing the lens and cleaning the contacts. that seemd to work well for me.

Nikon Coolpix s3 powers on OK when switch is on auto mode, but when switched to "Scene" mode cannot shoot, switch back to auto mode / movie mode, or turn off. If power is turn on when switch is in "Movie" mode, everything is OK. Help!

You need a new shutter box.
It may be worth cleaning the contacts on both camera and lens.
Clean the contacts in the lens mount using a fiberglass "pencil" designed specifically for cleaning contacts. These are available at just about any photo supply store/firm.

send it to nikon. seem like a common problem

You may want to make sure the contacts around the lens and mount on the camera are clean. Also, make sure the setting on the lens (if there is one) is not sitting just barely between manual and auto. Reset your settings to factory defaults and put all your dials on auto, and see if it still does it. If it does, then come back an update with any variations and experiences you've acquired from this.

Can you report what the dial and menu settings are?

My best assessment would be that the dial setting is on something other than Auto, like Manual, and the Aperture and/or shutter speed are way off. Flip it to Auto and take another shot. Report back.
