VISION YOU CAN DEPEND ON

Glass prism optical viewfinder with approximately 100% frame coverage

See every important element in your frame clearly and

precisely. The D800 offers approx. 100% frame coverage (in

FX format) from its slim pentaprism, giving you the visually

comfortable FX-format advantage and an unobstructed view

when shooting still images. The viewfinder image is not

only large and bright — the focusing screen is also carefully

designed to help you sense sharp focus intuitively, be it

manual or autofocus.

Precision 8-cm (3.2-in.), approx. 921k-dot, wide-viewing-angle LCD monitor with automatic monitor brightness control

The D800's large and sharp color LCD monitor

delivers bright, crisp image playback with

a much larger capacity for accurate color

reproduction. Using an antireflective structure,

you can count on clarity equal to that of the

D4, even under bright conditions. Moreover, if

monitor brightness is set to "Auto", the camera

automatically adjusts LCD brightness according

to the environmental lighting conditions

measured by the ambient brightness sensor,

allowing easy use of live view in both bright and

low-lit places — very useful when shooting video

and stills. The ability to magnify playback images

up to 46x (Large-size images in FX format) is

extremely helpful for spot focus confirmation.

READY FOR DEMANDING TASKS

Lightweight yet durable construction

Many important parts of the D800 have been designed

to achieve better durability and lighter weight. The result

is a camera approx. 10% lighter than the D700, yet just

as rugged. A magnesium alloy construction

protects the sophisticated technologies

against accidental shock, and weather and

dust sealing has been extensively applied and

severely tested, making the D800 as reliable

on the road as it is in the studio.

Conventional models

Air space between glass and panel causes reflections at

the surfaces of each part, resulting in some light loss.

Surface reflection is reduced and light loss greatly

decreased by the integrated structure of glass and panel.

Fast response time

The D800 is designed to respond immediately. Once the

strategically located switch is turned on, the camera starts

up in approx. 0.12 seconds* and your finger is in position

for shutter release. Release time lag is minimized to

approx. 0.042 seconds*, equivalent to that of the D3S, with

continuous approx. 4 fps capability in FX format, approx.

5 fps in 1.2x and DX format and approx. 6 fps capability in DX

format** with MB-D12.

*Based on CIPA Guidelines.

**When used together with batteries other than EN-EL15.

High-speed CF and SD dual card slots

Card recording speed is yet

another crucial element of a

smooth and productive shooting

experience. The D800 CF memory

card slot is compatible with the

latest UDMA 7. The SD card slot

is compatible with SDXC (Secure

Digital eXtended Capacity) and UHS-I. You can also use two

cards simultaneously for a number of functions, such as

recording JPEG and RAW data on separate cards, recording the

same data simultaneously on two cards for backup and more.

High-speed data transfer with USB 3.0

For a more productive tethered and transfer workflow, the

D800 is compatible with USB 3.0. When connected to

equipment featuring USB 2.0, speed is reduced to that of

USB 2.0.

High-precision, high-durability shutter

The D800's shutter unit has been tested to well over

200,000 cycles of release to prove durability and precision.

While the shutter unit designed to run at a speed range of

1/8,000 to 30 s, its intelligent self-diagnostic shutter monitor

automatically monitors actual

shutter speeds in order to correct

possible variances that can occur

over time.

High-precision sequential control mechanism

For true digital SLR

excellence, the camera's

mechanical structure, power

and precision are vital to

ensure indispensable speed

and reliability. That's why

Nikon utilized its engineering

expertise to refine the

powerful sequential control

mechanism that drives the

shutter, mirror, and aperture independently. As a result,

shutter release can be operated with mirror-up position

during live view. Because mirror-down movement is not

required, you can expect even quieter still live view shooting.

And as power aperture control operates via the stepping

motor, the sound of mechanical adjustment is reduced for

quieter and smoother control.

Efficient power management

A comprehensive re-working of the D800's circuits now

enables approx. 900 shots* of still image

shooting. All on one charge of an EN-EL15

Rechargeable Li-ion Battery.

*Based on CIPA Standards.

MB-D12 Multi-Power Battery Pack (optional)

Attach the MB-D12 to the

camera body to extend

battery stamina. The pack

accommodates a variety of

batteries (see specifications)

and utilizes the same integral magnesium alloy construction

and weather sealing as the D800 body itself. You also get

approx. 6 fps continuous shooting speed* in DX format. The

MB-D12 has its own dedicated shutter-release button and

command dials for vertical composition shooting.
