Discerning photographers always test the boundaries of their equipment, pushing it as far as they can to capture the most powerful images possible. In the 75 years since the introduction of NIKKOR lenses, Nikon has dedicated itself to helping photographers go the extra mile. With the D3 and D3X, Nikon utilizes its proprietary FX-format sensor for striking tonal gradation and detail. The story, however, doesn’t end there. By enlarging the size of each pixel of the D3’s 12.1 effective megapixels, Nikon’s FX format captures light with unrivaled accuracy, which in turn contributes to a significantly higher signal-to-noise ratio and wider dynamic range. The rich initial data of each image is then swiftly and carefully routed through a 12-channel parallel readout for 14-bit A/D conversion, which serves two professional demands — speed and precision. With the D3X, each of its 24.5 effective megapixels has been specially designed to carry a larger electrical charge for outstanding light transmission properties and a wider dynamic range. The D3X’s image sensor incorporates 14-bit A/D converters on the chip, delivering fast conversion, high signal-to-noise ratio and low power consumption.
Adding to this versatility, the D3 and D3X also offer you three different formats — FX format, DX format and 5:4 — delivering all the options to respond to a vast range of shooting situations.

In many fields of photography, reflexes and timing can make or break a career. That’s why Nikon’s engineers set out to radically improve speed, response time and recording time for the D3 and D3X.
Indeed, these cameras mark an incredible breakthrough. The D3 gives you options to master any shooting situation: 9 frames per second in FX format (12.1 megapixels) and up to 11 fps in DX crop mode (5.1 megapixels). The D3X, with its 24.5 megapixels, gives extreme-resolution photographers the chance to shoot up to 5 fps* in FX format and 7 fps* in DX crop mode (10.5 megapixels).
Whether professionals succeed or fail depends on their readiness and ability to capture the perfect moment. That’s why Nikon has minimized the response times of the D3 and D3X to nearly unnoticeable levels.
The D3 and D3X start up in approximately 0.12 seconds, and shutter-release time lag is an industry-leading approx. 0.04 second* (based on CIPA Guideline).
* For further information, please refer to the D3X’s shutter release time lag on the specifications page.
Nikon understands that for professional digital photography, exceptional speed means little unless it is supported throughout the entire process.
That is why Nikon has taken the comprehensive approach of optimizing the speed of processing, buffer memory, memory access, memory card recording and USB interface.
With these working together harmoniously, you can forget about the weight of the data and concentrate on capturing the moment.

The D3 and D3X cover the frame like never before with the world’s largest number*1 of AF detection areas. These 51 points create a dense net of focusing strength.
This means faster focus acquisition, even with quick and/or erratic subject movement.
The 15 areas that occupy the all-important center of the frame utilize cross-type sensors, for even more powerful detection.
Most important, all 15 cross-type sensors retain the same outstanding level of performance with any AF NIKKOR lens f/5.6 or faster*2 — in other words, all of your AF NIKKOR lenses can take full advantage of cross-type accuracy.
