The camera received 4 stars out of 5 in 's editor review and Photocrati's Nikon D90 review labeled the D90 a "best value" DSLR. 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. In 's camera sensor ratings, the D90 achieved a score of 72.6, placing it above its competitors and more expensive cameras such as the (71), (70.9) and (69.8).
