Push Af - Canon XF300 Instruction Manual

Adjusting the Focus
Options
[Instant]: Sets the autofocus mode to Instant AF. The focus is adjusted at
the highest speed. This mode is useful even when recording in
very bright or low-light surroundings. This mode uses both the
TTL system and external sensor for focusing.
[Normal]: Sets the autofocus mode to Normal AF. The autofocus
adjustment is made at a stable speed.

Push AF

During manual focus mode or Normal AF mode, press the PUSH
AF button and hold it pressed down.
• The autofocus (Instant AF mode) is activated as long as you hold the
PUSH AF button pressed down. You can also use the PUSH AF button
on the optional ZR-2000 Zoom Remote Controller.
NOTES
• When recording in bright surroundings, the camcorder closes down the
aperture. This may cause the picture to appear blurred and is more
noticeable toward the wide-angle end of the zoom range. Turn the
built-in ND filter on/off according to the screen display (0 72).
• When you attach the optional WA-H82 Wide Attachment to the
camcorder, Instant AF and PUSH AF are not available.
• Autofocus takes longer to focus when the frame rate is set to [30P] or
[24P] than when it is set to [60i].
• When recording under dark conditions, the focusing range narrows and
the picture may appear blurred.
• Autofocus may not work well on the following subjects or in the
following cases. In such case, focus manually.
- Reflective surfaces
- Subjects with low contrast or without vertical lines
- Fast moving subjects
- Through dirty or wet windows
- Night scenes
