Nikon D2H NEW Advanced AF System, Exposure metering, Exposure modes, Auto Exposure Bracketing

Image quality mode: Raw Lens: AF-S VR Zoom-Nikkor70-200mm f/2.8G IF-ED Exposure mode: Manual

Shutter speed: 1/1,000 sec. Aperture: f/5.6 White balance: Direct sunlight Sensitivity: ISO-equivalent 400

High-speed, high-precision AF delivers the stability and accuracy

that’s critical to all your photography

The highly advanced 11-area Auto Focus System and Auto Exposure functions add greater speed, precision and flexibility that make it possible to capture subjects faster, sharper and more efficiently.

Every aspect of D2H is built to support the need for speed.

NEW ADVANCED AF SYSTEM

New 11-area AF system features 9 cross-type cross-type AF sensors

The new advanced Multi-CAM 2000 AF Sensor Module ensures quick response and razor-sharp focus, even in challenging shooting conditions. The system features eleven AF sensors of which nine are scross-type sensors that effectively cover the majority of the image area. The nine cross-type sensors operate with AF Nikkor lenses that are f/5.6 or faster, and performance is not influenced by changes in f/stop; that means the sensors work with virtually the entire AF Nikkor lens lineup. With its new AF sensor array, an added advantage of the new AF module is its ability to easily focus on subjects in the upper or lower portions of the outer frame area. The large area covered by each sensor makes focus detection fast and precise to deliver performance that is free of AF hunting, even when acquiring very-out-of-focus subjects.

The AF System provides a selection of operating modes, each designed deliberately to ensure maximum speed and accuracy because, as an action photographer, you’ll confront so many different conditions that require an optimized mode.

of three to five active sensors and have the AF system focus on the closest item in the group. This mode is particularly useful when aiming to capture a subject that remains in a specific portion of a sports shot or other scene where a lot of action is taking place within the image area.

Exposure metering

3D Color Matrix Metering automatically calculates the optimum exposure value by evaluating brightness, color, contrast, selected focus area and subject-to-camera distance information, and then referencing the large onboard database. The combination of Nikon's exclusive 1,005-pixel RGB exposure/color metering sensor,

advanced algorithms that reference a database developed from over 30,000 scenes from actual photography, and finally high-speed processing results in automatic exposure upon which

Manual control is available from -5 to +5 EV in 1/3, 1/2 or 1 EV steps.

• Single Area AF

Single Area AF essentially lets you choose among and lock focus with any of eleven AF spot sensors. This eleven sensor pattern corresponds with classic composition techniques known as the “rule of thirds.” The selected focus area is indicated on the Top Control Panel, and can be confirmed through the focus indicators (red pointers) in the viewfinder.

• Dynamic AF with Focus Tracking and Lock-on™

If your subject moves from its original position once you’ve selected a priority focus area, Dynamic AF ensures accurate focusing by shifting instantly and automatically from your selected focus area to the one into which the subject has moved. Focus Tracking automatically follows a moving subject, and Lock-On™ continues to track your main subject, even if something momentarily blocks it in the viewfinder or it moves off an AF sensor. Nikon’s unique overlap servo method drives the focus movement of the AF system and the lens simultaneously to realize fast and accurate AF operation.

• Closest Subject Priority Dynamic AF

Automatically identifies one or more focus areas, as needed, to capture the subject the AF system determines to be the closest to the camera. This mode is ideal when your subject is against a distant background, or you want to quickly focus on the foreground subject.

• Group Dynamic AF

Group Dynamic AF delivers yet greater control over the composition of action shots. Narrow the range to a specific group

you can depend.

Center-weighted Metering concentrates 75% of its sensitivity within an 8mm circle and the remaining 25% in the surrounding area. You can change the diameter of the center-weighted circle using Custom Setting "b6".

Spot Metering can be used with Single Area AF operation to provide precise metering by reading a 3mm-diameter area that corresponds to the selected AF area. Or, use it with Dynamic AF and choose the sensor to be used for metering.

Exposure modes

[P]Programmed Auto with Flexible Program automatically sets the shutter speed and aperture. Flexible Program can be used to quickly choose a correct alternate exposure-combination setting.

[S]Shutter-Priority Auto offers a choice of shutter speeds from 1/8,000 to 30 seconds.*

[A]Aperture-Priority Auto allows you to choose from the complete range of aperture settings.*

[M]Manual gives you full control over all settings, including Bulb.*

*In [S], [A] and [M] modes, the default increment for adjustments to shutter speed, aperture and bracketing is 1/3 step (1/3 EV). The setting can be changed to 1/2- or 1-step increments using Custom Setting "b3".

Auto Exposure Bracketing

Automatic bracketing of 2 to 9 consecutive frames with EV values changing in increments of 1/3, 1/2, 2/3 or 1 EV. Changes for exposure will correspond with the mode’s automatically selected variable. Bracketing in [P] Mode incrementally changes the aperture and shutter, [S] Mode changes the aperture, and [A] Mode changes shutter speed.

Sensitivity (ISO equivalency)

Thorough testing to find the perfect combination of productivity and image quality revealed sensitivity of ISO-equivalent 200 to be the optimal starting point for the D2H. Sensitivity can be manually set from ISO-equivalent 200 up to 1,600. Custom Setting "b2" can also be used to boost the highest setting one or two steps beyond 1,600 ISO-equivalent. The advanced noise-suppression technology of the LBCAST image sensor and image processing engine greatly reduce picture noise, and are particularly effective in the challenging high-sensitivity range.
