The Nikon D2Hs was announced on 16th February 2005, it offers a range of improvements over the 18 month old D2H. The improvements appear to be split into two areas; firstly the camera's buffer has been increased and (possibly) also its method of buffering; the D2Hs can shoot continuously at eight frames per second for up to 50 JPEG frames (a 25% increase) or 40 NEF (RAW) frames (a 60% increase).
