The Nikon D90 is the upgrade to and next logical step up from the D80. And, much like the D80's similarities to the D200, the D90 pulls some of the D300's best bits; a newly designed 12.3megapixel sensor that, while not a direct transfer, is mightily similar - making for some of the highest quality, low-noise images throughout the entire ISO100-6400 range. Anyone familiar with the Nikon line-up of late will know that this can only mean good things. Thinkcamera.com have just posted their review of the D90 along with the kit lens.
