The heart of Nikon’s Total Imaging System, NIKKOR lenses are respected by the world’s leading photographers because of their exceptional sharpness, accuracy and durability. Used consistently on Nikon SLR cameras and NIKKOR lenses for over half a century, the Nikon F-mount format has been a trusted friend of passionate photographers since Nikon's F-SLR cameras were first introduced. Maintaining the same basic lens mount structure for so long means that users have access to an ever-broadening, ever-growing array of compatible lenses that can be used now and far into the future. Because professionals have to work to their best ability in any lighting situation, the ability to render better, sharper images is indispensable. NIKKOR is optically designed for better performance no matter what the location, intensity or direction of your light source in relation to the camera. Its Super Integrated Coating (SIC) is applied to all NIKKOR lenses for reducing ghost and flare, while lenses with Nikon’s exclusive, state-of the art Nano Crystal Coat minimize ghost and flare effects even when the light source is in the frame. NIKKOR lenses are rugged, as well. In order to withstand the rough conditions inherent to difficult assignments, NIKKOR lenses have undergone rigorous tests and are engineered to meet the highest standards of working photographers everywhere.

With the Scene Recognition System of the D3S and D3X flagship cameras, most sophisticated digital SLR lighting systems become even more intelligent. No matter which compatible Nikon Speedlights you use — the SB-900, SB-600 or SB-400 — you will appreciate the i-TTL improvements, especially when using a single Speedlight. That’s because instead of using the conventional 5-segment Multi Sensor to evaluate monitor pre-flashes in i­TTL Balanced Fill-Flash, the D3S and D3X utilize the 1,005-pixel RGB sensor for a more refined flash metering evaluation.

With this system, overexposure is reduced to a degree never before achieved, even with small subjects, which tend to be overexposed. Metering accuracy for a scene containing highly reflective objects has also been improved. These improvements are made possible with the highlight analysis function of the Scene Recognition System, which correctly calculates the brightness range to be reproduced and determines background exposure. This level of single-Speedlight sophistication can be indispensable for photojournalists or other professionals who rarely have a second chance to make the shot.

Enjoy complete control of your lighting environment. The Nikon Creative Lighting System supports various flash control features, including Advanced Wireless Lighting. You can control up to four groups of Nikon Speedlights, including the Master/Commander SB-900 and three remote i-TTL Speedlight groups. Advanced Wireless Lighting is as easy to use as an on-camera Speedlight: set flash modes, turn Speedlight groups on or off, and even control the flash exposure compensation, all from an on-camera Speedlight or Commander. Any photographer can experiment with the seemingly limitless creative potential of the system. There is no limit to the number of Speedlights in each group, giving you almost complete control over how you light your subject.

Professional assignments often require long distance travel. With the D3S, using the GP-1, you can adjust your camera’s time regardless of where you use it. Time adjustment function is also useful when you team up with other photographers to tackle an assignment as a group. In such situations, it is important that each camera’s clock is correctly adjusted, especially for the post-production image selection and editing process. By synchronizing the clocks of several D3S cameras via GP-1, your team will be ready for group assignments.
