This classy camera is as tiny as it is affordable, but it's no lightweight in handling, features, or performance. Except for its 6.1-megapixel image sensor, the Nikon D40 is physically identical to the newer, pricier 10.2-megapixel D40x. The D40x may have the edge in absolute resolution, but the D40's overall image quality is equivalent or better because it doesn't have to squeeze as many pixels into its sensor and thus can make the pixels larger. That reduces noise, which is very well controlled at higher ISOs. The D40's viewfinder is big enough and very bright.
