I'm generally a Canon fan in the general Canon vs Nikon wars, but the new buzz from multiple sources about the new Nikon D90 which has received critical praise for new advancements in camera technology.
The biggest feature that distinguishes this SLR from anything else has to be the D-Movie Mode, which records at 720p HD (1280 x 720 pixels) in Motion JPEG format.
It also has matching features from existing current-gen SLR technology such as decreased noise with ISOs up to 3200, 12.3MP CMOS sensor, built-in sensor cleaning, and a top-speed of 4.5FPS continuous shooting.
The camera shoots in SD/SDHC and the lens system mounts with a wide-range of existing Nikon AF-S lenses.
I'm thinking I need to jump ship! The video feature alone makes this camera one-of-a-kind Digital SLR with video support.
