Nikon has announced a second digital SLR today; the Nikon D300 confirming rumours reported last week.

The new camera will feature a 12.3 megapixel sensor and similar to the D3, features Nikon’s new EXPEED Image Processing System.

Other features of the D300 include the same new 51-point auto focus system with Nikon’s 3D Focus Tracking feature and two new LiveView shooting modes that allow users to frame a photograph using the camera’s high-resolution LCD monitor.

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 also employs a new self-cleaning sensor unit. Four different resonance frequencies vibrate the optical low pass filter in front of the image sensor to shake particles free and reduce the appearance of dust.

The D300 features rugged magnesium alloy construction complete with 3.0-inch LCD screen.

The D300 will be available in November 2007 for an estimated selling price of £1299.99 in the UK and $1799.95 in the US.
