(3) The Spot metering: Analyzes the center of the screen and determines the proper
exposure.
The meter operating time is adjustable from 3 seconds, 10 seconds or 30 seconds.
The AutoFocus (AF) point and the Auto Exposure (AE) point can be linked during
multi-segment metering. More on metering page 86.
Exposure Modes
The K-7 has 10 exposure modes and one User definable mode. The camera really
stands out with all of its available exposure modes. Basically, three major compo-
nents are the ingredients needed for a well exposed picture; the aperture, the shutter
speed and the media sensitivity. In the 35mm format era, the film was the media and
the film ISO was the sensitivity. It was difficult to change film before the entire roll
was exposed and the ISO was locked-in for the duration. It was impractical. With
the advent of digital cameras, the media is a CCD or CMOS and the ISO is adjust-
able at will. Pentax went one step further and developed a new exposure mode: Sen-
sitivity Priority. (Sv) At this time, I believe it is the only camera with this feature.
There is also a new SD Movie mode. The exposure modes are explained in detail in
Chapter 2.
The following list highlights each mode and gives a brief description of what it
does.
Green Mode:

Automatically sets shutter speed and aperture to the
proper exposure according to the Program Line when
taking pictures. * see page 65.
Theoretically, you could start shooting in this mode right
away. All the factory defaults are set to work in this
mode when you receive the camera. However, you will
want to customize the camera to your preferences. More
