Pre-PMA 2003, 15:00 TOKYO: Nikon today announced three new digital cameras, the Coolpix 2100, 3100 and SQ. This article is a quick preview of the three megapixel, three times optical zoom replacement to the Coolpix 885, the new Coolpix 3100. This preview is based on an early pre-production model, as such I won't be presenting any image samples or a particularly in-depth analysis of performance.
