When you click [Exec] in [One-shot AF], the camera will focus once using autofocus and then switch to manual mode. The following procedure enables you to adjust the focus appropriately. 1. Select [Auto (Aperture-priority AE)] in [Exposure], and move the aperture slider to the right limit to fully open the aperture. The depth of field becomes shallow, and you can adjust the focus appropriately. 2. To adjust the focus, click and hold the [Far] or [Near] button in [Adjust Focus], or click [Exec] in [One-shot AF]. 3. When you have finished adjusting the focus, change [Exposure] to an appropriate setting. Note H651 M64x When using [Adjust Focus], it is recommended that you use [Adjust Focus] in [Camera Angle] > [Camera Settings] (P. 47). [Fixed at infinity] You can set the focus so that it is fixed near infinity. 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. Note • Focusing may be difficult for the following types of subjects when using [Auto]. Difficult to Focus Subjects A white wall or other subject A slanting lacking bright/dark contrast subject A subject reflecting strong light A subject consisting of only A subject having no form, A subject seen slant lines or horizontal stripes such as flame or smoke through glass A fast moving subject A dark area or night view Subjects both near and far • 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.
