Focus Tracking

Glossary-2
Exposure compensation for available light is activated by changing the
shutter speed and/or lens aperture. Use the AE-L/AF-L (Auto
Exposure/Autofocus Lock) button, the Exposure Compensation button, or
Auto Exposure Bracketing.
In flash photography with a NIKON-dedicated TTL Speedlight, exposure
compensation can also be performed by varying the amount of flash output.
Camera-originated exposure compensation affects both the foreground
subject and the background; variations in flash output amount affect only
the foreground.
Programmed Auto: Camera sets both shutter speed and aperture for
correct exposure.
Shutter-Priority Auto: User selects shutter speed and camera sets
matching lens aperture for correct exposure.
Aperture-Priority Auto: User selects aperture and camera sets matching
shutter speed for correct exposure.
Manual: You select both shutter speed and aperture, following or ignoring
the meter's recommendations to achieve the desired exposure.
The numbers on the lens aperture ring and in the camera's LCD that
indicate the relative size of the lens aperture opening. The f-number series
is a geometric progression based on changes in the size of the lens
aperture, as it is opened and closed. As the scale rises, each number is
multiplied by a factor of 1.4. The standard numbers for calibration are 1.0,
1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32, etc., and each change results in a
doubling or halving of the amount of light transmitted by the lens.
Flexible Program temporarily shifts an automatically selected shutter
speed/aperture combination while maintaining correct exposure. That is, a
desired shutter speed or aperture can be selected in Programmed Auto
exposure mode.
Focus-Priority is given to Single Servo AF mode while Release-Priority is
given to Continuous Servo AF.
Enables the camera to analyze the speed of the moving subject according to
the focus data detected, and to obtain correct focus by anticipating the
subject's position—and driving the lens to that position—at the exact
moment of exposure.
