The Nikon D40X was an upgrade from the D40, keeping all the same features as the D40 while changing the sensor from a six megapixel one to a 10 megapixel one (hence the X). the D40 and D40X were introduced by Nikon as compact, "point-and-shoot" type SLRs, aimed at the photographer looking to get better pictures but not wanting to pursue more advanced photography.
Getting Started
Charge the battery first, then place it in the battery compartment at the bottom of the camera. Attach the neck strap, then attach a lens by lining up the dot on the lens with the dot on the camera, slotting the lens into the body and twisting counterclockwise to set the lens in place. Insert an SD memory card into the camera. The card should be formatted; to do this, turn on the camera, hit "Menu", then scroll to the wrench icon for the setup menu, then scroll to format memory card. This erases any existing data on the card. The card should be formatted periodically, usually after downloading existing photos to a computer.
Shooting Info
Unlike Nikon's other DSLRs, the D40 and D40X only have one LCD screen to display information. Pressing the Info button on the will change the display to reveal camera settings, including ISO (sensitivity of the sensor to light, like film speed), white balance settings (how camera sees white), aperture, shutter, remaining number of shots on the memory card, and image quality settings. These settings (except for remaining number of shots) can be changed by pressing the magnifying glass button on the bottom left of the camera and highlighting the item you want to change, then using the scroll wheel to change the setting up or down.
Manual Control
In the Aperture, Shutter, and Manual modes, a photographer can change settings manually with the small wheel near the top right side of the back of the camera. In aperture mode, rotating the wheel will increase or decrease aperture and in shutter the wheel will increase or decrease shutter speed. In Manual, rotating the wheel changes shutter speed; to change aperture, hold down the +/- button on the top right of the camera, next to the shutter button, and rotate the wheel.
