AF capability comparable to the D4 professional model – high-density 51-point AF system that includes compatibility up to f/8
With the newly developed Advanced Multi-CAM 3500DX autofocus sensor module, the densely located 51 focus points, supported by an algorithm equivalent to that of the D4, deliver amazing capturing power. AF detection is available down to an impressive -2 EV (ISO 100, 20°C/68°F), which is the brightness equivalent to a subject illuminated by moonlight.
Fifteen cross-type sensors cover the most frequently used center area. The center point performs as a cross-type sensor even at f/8. This enables AF shooting, with the effective aperture value slower than f/5.6 and faster than f/8 or at f/8 when an AF-S teleconverter is attached to the lens. For example, accurate autofocus is possible with the effective aperture value of f/8 by attaching a 2.0x teleconverter to a telephoto lens with maximum aperture of f/4. By combining a teleconverter with compact and lightweight DX-format system, you can enjoy supertelephoto AF shooting without bulky equipment and expand the photographic opportunities.
Furthermore, when the image area of 1.3x crop of DX is selected, the angle of view becomes equivalent to that of a lens with about double the focal length in 35mm format. As the cropped frame is almost entirely covered by the focus points, the camera demonstrates even more powerful capturing capability.
Of the 51 focus points, 11 can be chosen to shoot with, for quicker focus-point selection.
Contrast-detect AF, used in live view and movie recording, realizes faster focusing speed than that of the D300S/D7000. During movie recording, you can track a moving subject within the frame and continue focusing by selecting full-time-servo AF (AF-F) and subject-tracking AF. Whether in still-image shooting or recording movies, the AF system supports accurate and comfortable focusing.

Variety of AF-area modes selectable to match your subject
You can focus on the subject selecting one of the 51 points. This is ideal when you want to achieve precise focus on a particular part of stationary subjects, such as portraits or landscapes. It can be conveniently employed when creating a portrait with the focus on an eye of the subject.
Suitable for capturing moving subjects. Select one of 51 points as a priority focus point. If the subject briefly leaves this selected point, the camera will focus based on information from the supporting points surrounding it. The number of points employed in focusing can be selected from 9, 21 or 51, depending on the situation, such as movement of the subject and predictability of the movement. For all these options, the camera uses the selected and surrounding points to recognize the subject as an area, and continues focusing on the moving subject accurately in combination with continuous-servo autofocus (AF-C) of lens servo.
Choose when there is time to compose the photograph or when photographing subjects that are moving predictably (e.g., runners or race cars on a track).
Choose when photographing subjects that are moving unpredictably (e.g., field sports).
Choose when photographing subjects that are moving quickly and unpredictably at random, and particularly difficult to capture with the selected focus point (e.g., birds).
After you achieve focus on the subject with your selected focus point, the camera engages all 51 points and maintains tracking of the subject by automatically employing a new focus point according to the movement and changes of composition while the shutter-release button is pressed halfway. This gives you more compositional freedom when shooting subjects moving erratically from side to side or top to bottom in the frame. With Scene Recognition System that utilizes the 2016-pixel RGB sensor, this feature demonstrates excellent subject-tracking performance.
Using information from all 51 focus points, the camera automatically detects the main subject and achieves focus on it. When a G- or D-type lens is employed, the camera detects a human subject's position by distinguishing foreground and background while recognizing human skin tone for improved subject acquisition, thanks to subject identification by Scene Recognition System.
Note: Only the selected focus point is shown on actual images. Also, if you select focus points in a peripheral area of an image when "9 points" or "21 points" is chosen, the number of focus points actually used may be less than 9 or 21.
1.3x crop of DX that enables shooting distant subjects without bulky equipment, for both stills and movies [NEW]
The D7100 features two image areas for still images — DX format (23.5 x 15.6 mm) and 1.3x crop of DX (18.8 x 12.5 mm). The format in use can be easily confirmed in the viewfinder. For videos, the D7100 also employs DX-based movie format and movie image area based on 1.3x crop of DX.
In DX format, the angle of view becomes equivalent to that of a lens with approx. 1.5 times longer focal length*1. In the newly employed 1.3x crop of DX mode, it becomes equivalent to that of a lens with approx. 1.3 times longer focal length*1 than in DX format. As a result, the angle of view becomes equivalent to that of a lens with about double the focal length*1. With this camera, you can get closer to distant subjects even though it employs a relatively lightweight, compact lens system. In the 1.3x crop of DX mode, the 51 focus points cover nearly the entire frame, attaining extremely high capturing power even when shooting moving subjects.
