We've had a chance to use the Nikon Coolpix A - the company's DX-format, fixed-lens compact. The Coolpix A features a 16MP APS-C sensor with no optical low-pass filter and a 28mm equivalent F2.8 prime lens. Nikon has done a lot of work to make the Coolpix A consistent with its DSLRs, from its interface to its compatibility with accessories.
