In line with our commitment to serve the evolving demands of photographers and nurture new forms of expression, Nikon has developed a proprietary new large-format imaging sensor — the Nikon FX format CMOS sensor — that differs from the Nikon DX format. Used in the D3, this innovative sensor, which measures approximately 36.0 x 23.9mm, features a high signal-to-noise ratio as well as a very wide dynamic range and greatly expanded ISO sensitivity range. This results in unprecedented high-quality, low-noise images and nearly the same image composition format as 35mm-film cameras, long the accepted protocol of leading photographers.
As the performance of imaging sensors continues to evolve at a remarkable speed, Nikon places a high priority on adaptability in matching each new camera with the most suitable sensor, to deliver the finest possible images. Since the introduction of the D1 in 1999, Nikon has developed CCD, LBCAST and CMOS image sensors of various designs and performance. Indeed, by applying our accumulated experience in image sensor design, we’ve managed to introduce countless innovations. Since Nikon considers it imperative to provide the best that imaging sensor evolution has to offer, in a camera photographers can truly appreciate, we are constantly strengthening our engineering and manufacturing techniques and processes. The Nikon FX format CMOS sensor, designed to meet the increased demands of the D3, is a reflection of our core philosophy and technological leadership.
The Nikon D300, featuring a resolution of 12.3 effective megapixels, employs our DX-format CMOS sensor. This latest version of the Nikon DX-format imaging sensor, refined since its original appearance in the Nikon D1, is technically advanced. For the first time, Nikon has built A/D converters into the sensor, achieving high-speed data readout that enables continuous shooting at up to 8 frames per second* with low noise and minimal power consumption.
* With battery pack.

Nikon pioneered the Nikon DX format in the D1, emphasizing superior image quality with extra-high resolution in central areas of the lens.
The efficiently sized Nikon DX format also permitted Nikon to develop a more compact camera. With the Nikon DX format, the focal length of a lens appears to be increased by 50 percent, so a lighter, smaller telephoto lens can be used in place of a longer focal length lens, making equipment lighter and more portable.
The D3’s high-speed, high-sensitivity capabilities may not be required for every shoot. And many photographers tend to bring a selection of camera bodies, lenses and flash units with them. When the D300, employing the Nikon DX format, is viewed in terms of a balance of performance and mobility, the advantages are many and persuasive.
