6. Operating the Lens

6.1 Autofocus Operation

When attached to a compatible Sony E-mount camera, the lens will automatically engage the camera's autofocus system. Select your desired AF mode (e.g., AF-S, AF-C, DMF) on your camera body. The lens's internal focusing motor will provide fast and accurate focusing.

6.2 Manual Focus Operation

To use manual focus, set your camera to Manual Focus (MF) mode. Rotate the focus ring on the lens barrel to adjust focus. Your camera's focus peaking and magnification features can assist in achieving precise manual focus.

6.3 Aperture Control

The aperture of the lens is controlled electronically through the camera body. Adjust the aperture setting (f-stop) using your camera's controls in Aperture Priority (A), Manual (M), or Program (P) modes.

6.4 Firmware Updates

The integrated USB-C port allows for firmware updates to improve lens performance and compatibility. Visit the official VILTROX website for the latest firmware and instructions on how to update your lens.

7. Maintenance and Care

• Cleaning the Lens Elements: Use a lens blower to remove dust, then a soft lens brush. For smudges, use a clean microfiber lens cloth with a small amount of lens cleaning solution. Apply solution to the cloth, not directly to the lens.
• Cleaning the Lens Body: Wipe the lens body with a soft, dry cloth. Do not use organic solvents like paint thinner or benzene.
• Storage: Store the lens in a cool, dry, and well-ventilated place away from direct sunlight. Avoid storing in areas with high humidity to prevent mold growth. Attach both front and rear lens caps when not in use.
• Protection: The included 52mm UV filter provides an additional layer of protection for the front lens element against dust, scratches, and impacts.
