[Fixed at infinity]
You can set the focus so that it is fixed near infinity.
Note
• Focusing may be difficult for the following types of subjects when using [Auto].
Difficult to Focus Subjects
• It is recommended that you check that the camera is focused whenever you reboot the camera.
• The estimated focus ranges depending on the [Day/Night] setting are shown in the following table.
* Using infrared illumination from an external device may throw the camera out of focus.
You can use [Camera] > [Day/Night Mode Focus] > [Compensate for light source] to focus according to the wavelength of an
infrared light (P. 120).
[One-shot AF]
Use when [Focus] is set to [Manual]. When you click [Exec], the camera will focus once using autofocus and then switch to
manual.
[Adjust Focus]
If the [Focus] is set to [Manual], you can click and hold the [Near] and [Far] buttons to adjust the focus in the near and far
directions.
Important
• The focus you set is also applied to other users.
• Depending on the lighting used, focus may not be maintained when switching between [Day Mode] and [Night Mode]. Focus when
switching between Day/Night Mode can be set in [Camera] > [Day/Night Mode Focus].
• If you select [Manual] in [Exposure] and set the shutter speed to [1/1 sec], the camera will be out of focus if [Auto] is set. In this
case, adjust the focus with [Manual].
• If you set the focus [Manual], it will remain fixed.
• In conditions where an outdoor scene is captured from an indoor location through a glass window, the camera may focus on the
glass if there is dust or water on the surface. Install the camera at the shortest possible distance from the glass surface.
