3 Slow Shutter
Select the longest slow shutter speed used in the Auto Exposure mode when shooting a dark
image. NTSC: “Not Used”, “1/15”, and “1/8.” PAL: “Not Used”, “1/12”, and “1/6”. A longer shutter
speed results in a longer trail with a moving object. Select a speed appropriate for the shooting
scene (dStart Guide P.1-8).

The focusing range (approx) differs depend on the Day Mode or Night Mode. The
ranges for Wide and Tele ends are the same.
* When you are using an infrared lamp, the focusing range for “Auto” and “Auto (for
domes)” will be approximately 0.6m (23.6in) to , and for “Fixed at infinity”, it may
become out of focus depending on objects.
When focus adjustment is difficult (e.g., when shooting a night scene which has
low contrast), it is recommended to fix the focus to infinity.
