The Nikon D40 is an entry level digital single lens reflex camera.
Released in 2006, the Nikon D40 is a compact, entry-level, digital single lens reflex (DSLR) camera. Inside the Nikon D40, you will find a 6 megapixel CCD (charged coupled device) DX format sensor that has a 1.5 FOV (field of view) crop. This crop means the focal length of a lens on a full frame DSLR or film SLR is reduced when installed on a Nikon D40. A 50mm lens on Nikon D40 would have a field of view equivalent to a 75mm lens installed on a full frame DSLR or film camera. Troubleshooting the Nikon D40 in Auto mode starts with the battery.
Instructions
1. Remove and recharge the battery in the Nikon D40. If the camera starts to be unresponsive or if it simply won't work, check to see if the battery needs to be re-charged. Digital cameras like the Nikon D40 need battery power to drive the shutter, lens mechanism and focus the lens.
2. Press the "Info" button on the top of the camera just behind the shutter release. On the LCD (liquid crystal display) screen, you will see an information screen. The bottom right icon will tell you the metering mode in which you have the camera set. If your exposures are not correct or as accurate as you would like, check here to see the metering mode. In "Auto" mode, the camera will set the aperture based on the metering information it reads.
3. Press the "Info" button again, and in the right margin, third from the bottom, you will see the information for the camera's focusing mode. If your pictures are out of focus, make sure the camera is set to "AF-A" for auto-focus mode. When the camera is set for "Auto" mode, the camera does not automatically select how the lens will be focused.
