Engadget - Not ready to shell out $2,800 for Sony's full-frame RX1 point-and-shoot? Perhaps an APS-C compact is more within your league. Nikon's Coolpix A is the imaging giant's answer to Sony's fixed-lens flavor, sporting an 18.5mm (28mm equivalent) prime lens with a maximum f/2.8 aperture, "quick" autofocus performance, a manual focus ring and, at the center of it all, a 16.2-megapixel DX-format sensor. The idea here is that you'll get DSLR (or mirrorless camera) image quality and depth-of-field in a cam you can tuck away in your pocket. It's a concept we've seen manufacturers deliver on before, and now it's Nikon's turn.
