Reviews Word on the street

Nikon D90  vs D300 

Image noise control was extremely impressive though, with outstanding quality at 800 ISO and usable images even at 1600 and 3200 ISO.
Nikon D300

Like Canon, Nikon has a lot invested in lens-based optical-image stabilization technology, so the D300 lacks the in-body sensor-shift stabilization that Sony, Pentax, Olympus, and Panasonic offer.
Nikon D300

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.
