The viewfinder also allows viewing of all the important image information such as:
focus point indication in red, in-focus indicator, focus mode status, shutter speed,
aperture, exposure compensation, number of
image remaining, shake reduction status and
the current ISO setting.
In addition, the standard focusing screen is
interchangeable. Pentax offers three optional
focusing screens. An optional AF divided
matte screen combines the focus area brack-
ets with a grid to help composition. Another
optional AF scale matte screen provides a
scale to verify subject placement and a third matte only. Other companies now offer
focusing screens that fit on Pentax DSLR cameras. I have read good reviews about
focusing screens manufactured by Katz Eye™.

The standard eyecup is removable and the supplied eyepiece cover can be attached
to stop stray light from entering the chamber during long exposures. A viewfinder
loupe model 0-ME53 is available as an option. With this viewfinder loupe attached,
the finest details are easily visible. The 1.2x magnification helps if you wear glasses.
The 0-ME53 is bigger than the standard eyecup and consequently, you will not
smear the LCD with your nose.
A Diopter adjustment slider is located above the viewfinder and allows adjustment
from -2.5m-1 to +1.5m-1.
Focusing System
The K-7’s new SAFOX VIII Plus wide-frame autofocus system features 11 sensor
points (with nine cross-type sensors positioned in the middle). By adding the light
source type to its data range, and driven by a greatly improved algorithm, Pentax
improved the AF system assuring reliable, responsive autofocus operation superior
in speed and accuracy to the previous system. The K-7 also incorporates an AF-
assist spotbeam projector to improve auto focusing accuracy in the dark.
