An update of the D70, the D70s—the s is for Super!—improves the UI and includes a nicer battery. The specs are pretty standard: 6.1 megapixels, compatibility with Nikon Nikkor lenses, and RAW aka NEF mode for hi-res hotness.
Generally, this is a mid-level pro camera with lots of nice post-35mm features and sure looks pretty.
