The 12.3MP Nikon D300 features include the EXPEED Image Processing System, new 51-point auto focus system, 0.13s startup time, 45 millisecond shutter release lag time and a 3 inch screen. The D300 is capable of shooting at a rapid six frames per second and can go as fast as eight frames per second when using the optional MB-D10 Multi-Power Battery Pack. In continuous bursts, the D300 can shoot up to 100 shots at full 12.3 megapixel resolution.

The D300 will be available from Nikon Authorized Dealers beginning in November 2007 for an estimated selling price of $1,799.95. The Nikon D300 replaces the Nikon D200.
