3. Operating Instructions
3.1 Adjusting the Varifocal Lens
The 5-50mm varifocal lens allows for manual adjustment of focus, aperture, and zoom to achieve the desired field of view and image clarity. These adjustments are made directly on the lens barrel.
Figure 6: Lens Adjustment Components
- Zoom (W-T): Rotate the zoom ring to adjust the magnification level. 'W' typically indicates wide-angle (less zoom), and 'T' indicates telephoto (more zoom).
- Focus (Near-Far): Rotate the focus ring to achieve a sharp image. This is a manual focus lens, so precise adjustment is required.
- Aperture (Open-Close): Rotate the aperture ring to control the amount of light entering the lens and the depth of field. 'Open' allows more light and shallower depth of field, 'Close' allows less light and greater depth of field.

3.2 Achieving 4K Resolution
To fully utilize the camera's 4K (3840x2160) resolution capabilities, ensure that your viewing software and display monitor both support 4K resolution. If your software or display only supports lower resolutions (e.g., 1080P or 720P), the camera output will be scaled down accordingly.
