The new Nikon D90 DSLR camera got announced yesterday. We already reported about a Nikon D90 hands-on video report. Like always the major photography magazines and sites got a pre-production model of the new Nikon DSLR. DPReview published a detailed review using such a camera, which is pretty much identical to the final version of the Nikon D90.
The review also shows what the differences between the Nikon D90 and the Nikon D80.
Quote from the review: "Almost exactly two years after the D80 was announced comes its replacement, the rather predictably named D90. The D80 has been one of Nikon's quiet successes, and even today, despite being positively Methuselah-like in digital camera terms it continues to sell and often makes its way into our top 10 most clicked on cameras. Because it looks so similar to the D80 the D90 appears at first glance to be one of those rather subdued incremental upgrades, but dig a little deeper and you'll find there's plenty to keep Nikon fans happy."
