Nikon today unveiled the 12.3-megapixel D300 that is as fast as the newly introduced D3 SLR.  According to Nikon the camera power ups in 0.13 second and has a 45-millisecond shutter lag. Nikon is using the same EXPEED image processing system, which is used in their flagship D3. The camera has 51-point auto focus, shoots eight frames per second and can deliver continuous bursts of up to 100 consecutive shots. The camera also has 3D tracking with automatic focus point switching that takes advantage of 51 AF points as it uses color and light information to track the subject. You can grab this more affordable camera for $1800 in November.
