Depends on who's advertising it
Inheriting and expanding on the exceptional functionality of the EOS-1D Mark II, released in April 2004, the Canon EOS-1D Mark II N reaches new heights in both functionality and camera responsiveness. The camera incorporates a large APS-H-size (28.7 x 19.1 mm) CMOS sensor with 8.2-million effective pixels and, maximizing the performance potential of the sensor, Canon's proprietary DIGIC II high-speed imaging processor. Designed to meet the rigorous demands of professional news, sports and studio photographers, the EOS-1D Mark II N delivers the world's highest* continuous shooting speed of approximately 8.5 frames per second for up to a maximum 48 consecutive frames** in a sequence.
Canon's EOS-1D Mark II N features a revolutionary new Picture Style function which consolidates and advances the processing parameters and color matrix settings. Users can achieve optimized images by simply selecting from six preset settings --Standard, Portrait, Landscape, Neutral, Faithful, and Monochrome-- to match their shooting objectives, just as they would select the type of film according to the desired effect. Compared with previous models, the new function offers approximately double the adjustment range for sharpness, contrast, color saturation and color tone. Picture Style will also be incorporated in future Canon digital SLR cameras to ensure unified and consistent image characteristics across the EOS digital lineup.
The EOS-1D Mark II N sports a large 2.5" LCD monitor with approximately 230,000 dots and a wide 170-degree viewing angle for optimum visibility during playback. Moreover, the camera offers such improved image playback functions as a magnified view to almost pixel-equivalent-scale from any selected AF point, enabling users to quickly check the focus before taking a shot. Users can also check the focus with a magnified view immediately after shooting using the Quick Review function.
In response to requests from professional users, Canon has included a host of new features in the EOS-1D Mark II N, including more complete information displays, simultaneous split recording of RAW/JPEG images, an automatic new-folder-creation function, and automatic noise reduction for long-exposures. Additionally, a new precision-matte focusing screen that enables the user to more easily pick the point of sharpest focus is available as an option.
N's Basically the same camera as the ii, a few minor tweeks, but a word of warning that you'll be all fingers and thumbs to start with, the ergonomics of the controls are completely different to most of canon's other models, but you'll get use to it.
