With this camera, you can get closer to distant subjects even though it employs a relatively lightweight, compact lens system. As a result, the image area becomes equivalent to that of a lens with about double the focal length* 1. 1.3 times longer focal length*1 than in DX format. In the newly employed 1.3x crop of DX mode, the angle of view becomes equivalent to that of a lens with approx. In DX format, the angle of view becomes equivalent to that of a lens with approx.
How to set in camera lens distortion for d7100 movie#
For videos, the D7100 also employs DX-based movie format and movie image area based on 1.3x crop of DX. The format in use can be easily confirmed in the viewfinder. 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). Whether in still-image shooting or recording movies, the AF system supports accurate and comfortable focusing.įocus point compatible with aperture slower than f/5.6 and at f/8 or fasterġ.3x crop of DX that enables shooting distant subjects without bulky equipment, for both stills and movies Not only phase-detection AF but also contrast-detect AF, which employs image sensor data, during live view shooting or movie recording has become significantly faster than that of the D300S. Of the 51 focus points, 11 can be chosen to shoot with, for quicker focus-point selection. As the cropped frame is almost entirely covered by the focus points, the camera demonstrates even more powerful capturing capability.
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.įurthermore, 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. 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. This enables AF shooting, with the effective aperture value slower than f/5.6 and at f/8 or faster when an AF-S teleconverter is attached to the lens.
The center point performs as a cross-type sensor even at f/8. AF detection is available down to an impressive -2 EV (ISO 100, 20☌/68☏), which is the brightness equivalent to a subject illuminated by moonlight.įifteen cross-type sensors cover the most frequently used center area. 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.
