Nikon's high-end 36MP D800 and D800E DSLRs have been consolidated with the release of the D810. It is not simply an upgrade: major changes substantially extend its capabilities and make the camera more attractive to buyers considering a move to a full-frame camera. Some features from the D4s have been incorporated into the D810. Videographers, for example, will be pleased with additions to its video feature set. Other refinements include a redesigned shutter and mirror mechanism to reduce the shock of shutter actuation, which can reduce resolution. There's also a new S-Raw mode for reduced-resolution raw capture.
