Setup

Mounting the Lens

1. Align the red dot on the lens barrel with the white dot on your Sony E-Mount camera body.
2. Gently insert the lens into the camera mount.
3. Rotate the lens clockwise until it clicks into place, indicating it is securely locked.
4. To remove the lens, press and hold the lens release button on your camera body and rotate the lens counter-clockwise until it detaches.

Firmware Updates

The lens features a USB Type-C upgrade interface (11) for convenient firmware updates. Connect the lens directly to your computer using a USB-C cable and visit the VILTROX official website for the latest firmware and update instructions.

Operating the Lens

Focusing Mode Switch (MF/AF)

Use the AF/MF switch (5) on the lens barrel to toggle between autofocus (AF) and manual focus (MF) modes. In AF mode, the camera's autofocus system will control the lens focus. In MF mode, you can manually adjust focus using the focusing ring (3).

Aperture Control

The lens offers two ways to adjust the aperture:

• Automatic Aperture: Set the aperture ring (7) to 'A' (Auto) position. The camera will then control the aperture settings.
• Manual Aperture: Rotate the aperture ring (7) to select your desired f-stop (from f/1.2 to f/16). The 'Click Switch' (6) allows you to enable or disable click stops for smooth aperture changes during video recording.

Focus Lock Button

The focus lock button (4) can be customized via your camera's menu to perform various functions, such as AF-ON or focus hold.

Lens Hood

Attach the included lens hood by aligning its index with the lens hood position (1) and rotating until it locks. The lens hood helps to prevent flare and ghosting caused by stray light and offers physical protection to the front element.

Maintenance

Cleaning the Lens

The lens features an HD Nano Coating. To clean the lens elements, use a soft, lint-free cloth specifically designed for optical surfaces. For stubborn smudges, use a small amount of lens cleaning fluid applied to the cloth, not directly to the lens. Avoid touching the lens surface with your fingers.

Weather Protection

The VILTROX AF 75mm F1.2 Pro E Lens is designed with three layers of protection against dust and water droplets. While it offers professional-level protection, it is not fully waterproof. Avoid prolonged exposure to heavy rain or submersion in water. Always wipe off any moisture immediately after exposure.
