Just posted: Our review of the Nikon Coolpix A. With a 28mm-equivalent wideangle lens, and the same 16MP DX format sensor as used by the D7000 SLR, the Coolpix A is designed as a serious compact camera capable of professional-quality results. But it's up against stiff competition, in the shape of the similarly-specified but cheaper Ricoh GR that was announced a month later. In our 16-page comparative review, we take a detailed at how the Coolpix A measures up to the challenge  to the challenge posed by its close rival. Our review of the Ricoh GR should follow in the next couple of weeks.
