Retail info

The D40 is a Nikon entry-level digital SLR, announced November 16, 2006.^[2] Compared to its predecessor, the D50, the D40 has several features removed, a few added, and a lower price: US$499.95 ESP as of November 2009 with the 18–55 mm G-II kit lens,^[3] positioning it as an entry-level model compared to the D80. The D40x (released March 6, 2007) has a 10 megapixel maximum resolution, up from 6 megapixels of the D40.

The D40 was the first Nikon DSLR that only autofocuses using F-Mount lenses with internal focus motors such as AF-S and AF-I, as do later models, including the D40x, D60, D5000 and D3000.

[edit] Features

The Nikon D40 is less expensive than the Canon EOS 400D (also known as Digital Rebel XTi in the United States), the Pentax K110D, and the Olympus E-400, and is competitively priced against high-end bridge cameras (the D40 and D40x do not have live preview, unlike bridge digitals). It was launched accompanied by a new small kit lens, the AF-S DX Zoom-Nikkor 18–55 mm f/3.5-5.6G ED II.^[4]

Despite having been on the market since late 2006, the D40 holds some benefits over its newer competition such as the Nikon D40x, D60, and Canon Rebels. Because only 6 megapixels are fit onto the standard Nikon DX format sensor, the sensitivity of each pixel is higher. The default sensitivity on the D40 is ISO 200, and the D40 adds a ISO 3200 speed (listed as "Hi1" in the camera menu). The D40 has a higher 1/500 flash sync, useful for daytime fill-flash. This compares to the typical 1/200 sync speed of other entry level and even some semi-pro DSLR cameras such as the Canon 40D with its 1/250 sync speed.

The D40 lacks a built in autofocus motor, which means that only Nikon lenses designated with AF-I and AF-S or compatible can be used in autofocus mode.^[5]

[edit] Reception

The Nikon D40 was tested by various independent reviewers^[6]. The D40 is the lightest and cheapest Nikon SLR so far.

[edit] Nikon D40x

On March 6, 2007, Nikon introduced the D40x, a sister camera to the D40.^[7] 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 (as noted above, each pixel in the 10.2-megapixel sensor receives less light than the pixels in the D40 sensor). It has a flash sync speed of 1/200 seconds compared to the D40's 1/500 seconds. It is otherwise identical.

The launch was accompanied by the introduction of a new consumer-level telephoto zoom with vibration reduction, the AF-S DX VR Zoom-Nikkor 55-200mm f/4-5.6G IF-ED.

Nikon ceased production of the D40x in December 2007, shortly before they introduced its successor, the Nikon D60.
