3.6 Focus Areas
You can select the focus area that best suits the kind of pictures you
intend to take. Push and hold the focus selection button

for at least
one second; then turn the front or rear dial to select the appropriate
focus area. The selected focus area can be seen on the main LCD panel.
When the preferred focus mark is selected, press the SET
B

the focus point selector button

to exit the setting.
Multi Area Focus
When selecting multi area focus, the focus points are positioned in the
viewfinder according to the illustration shown to the left.
If multiple objects are located within the focus frame, the camera locks
on to the object closest to the camera.
Spot Focus Area
When spot focus is selected, the camera locks on to objects positioned
in the center of the viewfinder. The camera focuses on the center mark in
the focus frame
[ O ] in the viewfinder.
Manual Focus Mode (M)
To attain full manual control of the focus function you can change to
manual focus mode in two ways.
1. All lenses: Turn the focus mode selector lever to
M
(Manual focus
mode).
2. Manual Focus operation for telephoto and zoom lenses: All
newer Mamiya, Phase One and Schneider-Kreuznach lenses can be
switched from Auto Focus to Manual Focus by using the AF ring or
slider fitted on the lens.
For lenses with AF slider, slide the focusing ring on the lens backward until
it clicks. When this is done, the Auto Focus inscription on the lens barrel is
covered and the lens can then be focused manually. For lenses with an AF
ring, simply rotate the AF ring to the MF position to select manual focus.
Adjust the Focus
Turn the lens focusing ring until the subject is in focus. When correct
focus has been achieved, the focus mark in the viewfinder lights up.
