 The D40's small size and low price made it attractive to point-and-shoot photographers moving up to their first SLR, however it does contain features and improvements that would appeal to enthusiasts as well.Despite having a comparatively lower resolution for a DSLR introduced in 2006, the D40 held 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.
