Released a little over two years after D3, the D3S represents Nikon's attempt to build on the foundations laid by the D3's runaway success. Ergonomically, very little has changed. In fact the D3S and its predecessor are difficult to tell apart at a casual glance, but the D3S does offer some significant improvements, not least a new 720x1280p video capture mode, and several minor tweaks designed to make the new camera more competitive. These include a new 'Quiet' shutter release mode (first seen in the D5000), in-camera dust reduction, and a choice of four image area formats, including DX, and a new 1.2x crop option.
