Think of the 10.2-megapixel Nikon D3000 as the smaller cousin of the long-standing models it replaces. With the $550 D3000, Nikon improves on its previous entry-level model (the Nikon D40), refining the design and adding a slew of features that make the D3000 a great choice for point-and-shoot owners looking to explore the digital SLR world. We appreciated the improved autofocus of the D3000, as well as its compact design and light weight.
