 also published a highly positive assessment, but noted that the only weakness seemed to be that matrix metering on the D90 is tied too strongly to individual focus points, and therefore allows highlights to be clipped in other areas of an image.

As noted above, one of the most notable features of the Nikon D90 is that it is the first digital SLR camera to include high definition video capabilities. While most reviewers gave the D90's HD video high marks, Nikon expert Thom Hogan noted that the HD video capability, while novel, was not yet refined, providing only mono sound, and being subject to video flaws such as apparent distorted motion of stationary objects when panning.
