The viewfinder itself is very good, with a large bright screen and clearly marked AF points, and none of the tunnel-like appearance of some other APS-C sized DSLRs.

Images begin to look "processed" at ISO 800; you can begin to see some sharpness degradation starting at ISO 1,600, but it doesn't become obtrusive until ISO 3,200.

Really, though, the Nikon D90's features, performance and value are so immense that it has to be given one of our all-time highest scores.
