FOCUSING ( DISTANCE )
STILL PHOTOGRAPHY FUNCTIONS
The distance from the subject to the camera is referred to as the shooting distance.
When the shooting distance is set correctly and the image appears sharp, the image is focused.
I Three focusing methods
There are mechanisms for focusing: (1) Single AF (S-AF); (2) Continuous AF (C-AF); and (3)
Manual focus (MF).
S-AF: Use S-AF for normal photography. In this mode, the camera focuses each time the Shutter
button is pressed down halfway.

The AF sensor
The FinePix S7000 uses an external AF sensor (external-light passive phase difference AF) that
features faster AF operation than previous models. The external AF sensor does not function
when Macro mode, Super macro mode, the digital zoom, AREA or C-AF focusing is used or
when "ADAPTER-YES" is selected. It may take longer to focus if the external AF sensor is
soiled (➡P.113).
C-AF: Use C-AF when photographing moving subjects. When this mode is set, the camera
focuses continuously on the subject in the center of the screen. See P.49 for details.
MF: The focus is adjusted by turning the focusing ring manually. See P.48 for details.
I Causes of focusing errors and the solutions
Cause
The subject is not in the AF frame. Use AF lock (Focus mode: AF (CENTER))✽1 or MF.
Use AF lock (Focus mode: AF (CENTER))✽1 or MF.
The subject is not suited to AF.
Turn Macro mode on or off (✽2).
The subject is outside the shooting range.
The subject is moving too quickly. Use MF (pre-setting the shooting distance for a shot (lock pin))

background with strongly contrasting
elements)
STILL PHOTOGRAPHY FUNCTIONS
EXPOSURE ( SHUTTER SPEED AND APERTURE )
Exposure refers to the light that hits the CCD or the total amount of captured light and determines
the brightness of the image.
The exposure is determined by the combination of aperture and shutter speed. In AE (automatic
exposure), the camera automatically determines the correct exposure, allowing for factors such as
the brightness of the subject and the sensitivity setting.
The graph at left shows the way the aperture and shutter speed settings can
be changed while maintaining the same exposure level.
h When the exposure is decreased by one step, the shutter speed also
decreases by one step (the dot moves upper left).
h When the exposure is increased by one step, the shutter speed also
increases by one step (the dot moves lower right).
h Combinations that result in the shutter speed or aperture being outside the
available range of settings cannot be selected (white dots).
h In the " ", " " and " " photography modes, it is easy to select different
settings along this line.
h Selecting settings that run parallel to this line by adjusting the brightness of
the photographed image is referred to as exposure compensation.

When you cannot get the correct exposure
AE lock: Determines and fixes the exposure at a target level. Use the following procedure to take a
picture using AE lock:
Press the "AE-L" button (sets and locks the
exposure). ➡ Press the Shutter button down
halfway (sets and fixes the focus). ➡ Press
the Shutter button down fully (takes the
picture).
Exposure compensation:
This function uses the exposure level set by
the AE function as a reference (0) and then brightens (+) or darkens (–) the image. By
selecting Auto bracketing, you can shoot 3 frames, one underexposed (–), one at the
reference exposure (0) and one overexposed (+).
Shutter speed
When shooting a moving subject, you can either "freeze the motion" or "capture the sense of
movement" by adjusting the shutter speed.
