Chapter 1 - Know your K-7
There are two autofocus modes and one manual mode so you have total control of
the camera focusing abilities.
Indeed, the K-7 offers a choice of two autofocus modes; AutoFocus Single (AF-S)
and AutoFocus Continuous (AF-C), which maintains focus of a moving subject as
long as the shutter release button is pressed halfway or the dedicated AF button is
activated. The camera autofocus system can be activated by pressing the shutter re-
lease halfway. (It can be set on or off) It can also be activated by pressing the AF
button located on the back of the camera about where your thumb is positioned
when holding the camera.
The Manual Focus (MF) mode gives you complete control over focusing. The K-7
has 100% backward compatibility with all of the 24 million plus lenses ever manu-
factured by Pentax. Using a non-autofocus lens is permitted, and, by pressing the
shutter release button halfway while manually focusing, the focus indicator will ap-
pear and a beep (optional) will be heard to confirm that focus is achieved. With
manual lenses, only center focus is available. More on focusing page 96.
The K-7 permits the adjustment of the AF focusing position for all lenses used or for
selected lenses (up to 20 lenses). This new adjustment is available in the Custom
Setting menu, and you can always reset the adjustment to the factory defaults.
Metering System
A new 77-segment multi-pattern metering system was
developed for the K-7. It greatly improves light-metering
accuracy. By accurately analyzing various types of data
(such as the image’s composition and format between
upright and horizontal, and the subject’s distance and
magnification) transmitted from the sensors in the
camera body, this system greatly improves the accuracy
of exposure control.
(1) The Multi-segment metering: Accurately assesses the balance between the
bright and dark areas within the segments automatically.
(2) The Center-weighted metering: Measures the entire screen with an emphasis
on the center and determines the proper exposure.
