Zoom/Focus adjustment
It is possible to adjust the angular field of view using the zoom and the extra optical zoom.
Adjust the focus setting by moving the lens focus to the appropriate position.
Manual and auto adjustments are available.
[Zoom ratio designation]
The zoom and focus can be adjusted at the same time.
Operate the slider to enlarge/reduce the angular field of view adjustment outline in the image. When adjusting the zoom ratio to the “Tele” side, only the angular field of view adjustment outline is reduced, and it is possible to determine the zoom ratio while checking the angular field of view after zooming is performed. When adjusting the zoom ratio to the “Wide” side, the image itself is zoomed out of or the angular field of view adjustment outline is enlarged, and it is possible to determine the zoom ratio while checking the image size after zooming is performed. After the angular field of view adjustment outline is adjusted, zooming is performed, and the auto focus function starts to automatically adjust focus based on a subject located in the center of the screen by clicking the [Execute] button.
Note
•
The red area of the slider and angular field of view adjustment outline represents optical zoom, and the yellow area represents extra optical zoom. The supported optical and extra optical zoom ratios vary depending on the model and the selected image capture mode.

•
When images in the near-infrared light area change from color to black & white, images may be out of focus due to the nature of optical properties. In this case, the focus can automatically be corrected by selecting “Auto” or “Preset” for “Adjusting method” (the focus will not automatically be adjusted according to the illumination level change once the focus is corrected).
[Adjusting method]
Select the focus adjustment method upon switching between the color mode and the black & white mode.
•
Auto: Adjusts the focus function automatically and corrects the focus when switching between color and black & white images.
•
Preset: Performs the preset movement to each specified focus position when switching between color and black & white images. The preset position is the focus position specified last time, which was automatically memorized for each of color images and black & white images.
•
Fix: Fixes the position after adjusting the focus either automatically or manually.
•
Default: Auto
