The Nikon D40 is a 6.1-megapixel DX format DSLR Nikon F-mount camera announced by Nikon on November 16, 2006. It replaces the D50 as Nikon's entry level DSLR. It features a 2.5-inch 230,000-dot resolution LCD monitor, CCD sensor with ISO 200-1600 (3200 Hi-1) and 3D Color Matrix Metering.

The D40 was the first Nikon DSLR without an in-body focus motor. Autofocus requires the use of a lens with an integrated autofocus-motor.[4]

In March 2007, Nikon released a sister model, the D40x, which included a 10.2-megapixel sensor and several other changes over the original D40.[5]

Reception

Reviews of the Nikon D40 have been generally favorable due to its ergonomics and image quality.[6] It received some criticism for some design compromises Nikon undertook to keep the D40's price and size competitive.[7]

Nikon D40x

On March 6, 2007, Nikon introduced the D40X, a sister camera to the D40.[5] While identical in external design to the D40, it has a 10.2-megapixel CCD sensor, continuous shooting up to 3 frames per second, and a base sensitivity of ISO 100. It has a flash sync speed of 1/200 of a second.

A new consumer-level telephoto zoom with vibration reduction debuted alongside the launch. Nikon ceased production of the D40X in December 2007, shortly before they introduced its successor, the Nikon D60.
