Adjusting the Focus

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.
Peaking
You can turn the PEAKING knob on the
viewfinder to use the peaking function. Edges are
emphasized in the monitor picture, which
facilitates manual focusing.
The recorded video signals are not affected.

Adjusting in MF Mode

When you slide the focus ring forward (toward
the lens hood), and set the FOCUS switch to M
(manual), the focus mode becomes MF mode, in
which focus adjustments are manual but auto
focus is available only when necessary.
