What is the pixel pitch of the Nikon D40X?

The Nikon D40X provides 10 megapixels from an APS-C sensor. This pixel density gives rise to a size of the individual pixel of 6.11µm.

The pixel size or pixel pitch can be calculated by dividing the sensor area by the pixel count and then taking the square root. In particular, the sensor in the Nikon D40X measures 23.6mm in width and 15.8mm in height, so that the total imaging area of the sensor amounts to 373 mm². Moreover, the D40X has 3 872 horizontal pixels and 2 592 vertical pixels, for a total of 10 megapixels. Then, the size (height or width) of each individual pixel can be calculated as the square root of the ratio of the sensor area (373 mm²) to the MP count (10 036 224).

Larger pixels provide advantages with respect to gathering light, particularly in low-light situations. Large pixels notably have a better signal to noise ratio, meaning that they can better differentiate between incoming photons and the noisy signals that the internal processes of the camera create. As a result, big pixels are particularly helpful to the photographer when shooting with high ISO settings.

Sensor specs and performance

The table below compares the sensor specs of the Nikon D40X to those of several similar cameras. The reported DXO values are indicators of the sensor's imaging quality (higher is better), covering color depth (DXO Portrait), dynamic range (DXO Landscape), and high-ISO noise (DXO Sports). Larger sensor cameras tend to outperform cameras of the same generation that are equipped with a smaller imager. On the other hand, larger sensors are more expensive and require bigger and heavier lenses than smaller light receptors.
