Low noise high ISO delivers faster shutter speeds, smaller apertures for sharper, cleaner images

Rich tonal gradation, wide dynamic range: 14-bit

A/D conversion followed by 16-bit image processing

Another key to the D700's outstanding image

quality is Nikon's powerful, state-of-the-art

EXPEED image-processing, a technology it

shares with the D3. Rich data captured with

the Nikon FX-format 12.1-megapixel CMOS sensor maintains

an extremely high signal-to-noise ratio throughout 14-bit

A/D conversion and the numerous stages of 16-bit image

processing. This ensures smooth tonal gradations, the finest

shadow details and continuous transition even in highlights

— delivering unparalleled results in an astounding variety of

lighting situations, be they well-lit, backlit or poorly lit.

Colors remain well-saturated and accurate even in

transition, contributing to image depth that is simply

not possible with lesser cameras. This technology

applies not only to Nikon's NEF (RAW) files, but also to

JPEG files, which often require no post-processing and

are ready for immediate printing. Nikon's exclusive EXPEED

technologies process rich data at phenomenal speeds. And

unlike many digital cameras, everything is handled by a single

engine, conserving significant battery power. This, combined

with the large buffer memory, gives you greater breadth in

crucial situations, including extended shoots of fast-moving

subjects, such as sports or wildlife.

Clean files from ISO 200 through 6400

The D700's high signal-to-noise ratio contributes to

impeccably clean image files across the broadest span of

ISO settings. The D700's standard range extends from ISO

200 to ISO 6400, and whichever setting you select, the D700

delivers outstanding image quality. Now, you can choose high

ISO settings without hesitation and be assured of images

that exhibit remarkably low noise. And when conditions

demand it, you can also go lower to ISO 100 and higher to

ISO 12800 or even ISO 25600.

Comprehensive strategy to reduce noise

The D700 is designed to reduce noise even before the menu-

activated High ISO NR settings are applied. And at higher

ISO settings of 2000 and over, with the High ISO NR turned

on, it's activated automatically but in a manner designed to

give you rich, satisfying, natural saturation a world beyond

the synthetic appearance of conventional image processing

systems.

Superior results instantly, even in difficult lighting

conditions

Access to high ISO settings that deliver superior image

files gives you so many more exposure options for shooting

exceptional pictures in situations that were formerly beyond

your grasp. Poorly lit scenes that used to take time for

lighting setup can now be captured immediately. When

shooting in more subtle conditions, such as on an overcast

day, you won't have to sacrifice aperture settings for the

sake of shutter speed. Simply boost the ISO and use a faster

shutter speed to achieve superior results. At locations where

tripods and monopods are prohibited or are inconvenient to

use, you can still obtain superb handheld results. And with

NIKKOR VR (Vibration Reduction) lenses, the shot you want

is a given. Scenes that you long considered difficult or even

impossible are yours for the taking, and capturing them has

never been easier.

Auto ISO setting

For shooting opportunities where you need to deal with

constantly changing light, ISO sensitivity auto control can

be a major advantage, eliminating the need to sacrifice

either aperture or shutter speed. Taking pictures with ISO

sensitivity auto control enables you to limit how high you

want the camera to allow the ISO to rise while selecting

your preference for slowest permitted shutter speed. Now

you can go with your instincts in Programmed- or Aperture-

priority auto, or simply lock the aperture and shutter speed

combination you want in manual mode and let the D700

judge the lighting situation for you, determining the optimum

ISO for constant exposure results.

Active D-Lighting

Automatically regulating the dynamic range when the contrast

is too great lets you preserve highlights, such as those in the

sky or a clear halo around the sun, and shadow details. The

D700 employs Nikon's new Active D-Lighting, which works

automatically when needed, so you can leave it on, knowing it

will activate only when conditions indicate a need.
