Adjusting The Focus; Adjusting In Full Mf Mode; Adjusting In Mf Mode - Sony PMW-320K Operating Instructions Manual

Adjusting the Focus

The lens supplied with the PMW-320K allows
you to adjust the focus in the following three
ways.
Full MF (full manual focus) mode
This mode supports focusing with the focus ring
only.
Without changing your grip, you can focus all the
way from ∞ to the shortest shooting distance.
MF (manual focus) mode
In this mode, auto focus is enabled temporarily
when you press the PUSH AF button.
You can also use the MF assist function.
AF (auto focus) mode
In this mode, auto focus is always enabled.
The focus ring and the PUSH AF button are also
enabled.
Note
The lens is designed with an extra margin at the infinity
∞
position ( ), to compensate for focus drifting due to
variations in temperature. When shooting a subject at
infinity in MF or Full MF mode, check the picture in the
viewfinder as you focus.

Adjusting in Full MF Mode

When you slide the focus ring back (toward the
camcorder), the focus mode becomes Full MF
mode, in which all focus adjustments are manual.
Note
When you slide the focus ring back, the focus instantly
moves to the mark position.
Focus by turning the focus ring while viewing the
viewfinder.
The distance indications on the ring are valid in
Full MF mode. The distances where the picture is
in focus correspond to absolute positions of the
focus ring.
