Setup

1. Unpacking: Carefully remove the lens and all accessories from the packaging. Verify that all items listed in the "What's in the Box" section are present.
2. Attaching the Lens:
   • Remove the rear lens cap and the camera body cap.
   • Align the mounting index (white dot) on the lens with the corresponding index on your Nikon Z-mount camera body.
   • Gently insert the lens into the camera mount and rotate it clockwise until it clicks into place. Do not force the lens.

Operating Instructions

Autofocus (AF) / Manual Focus (MF) Switching

The lens features an AF/MF switch for seamless transition between autofocus and manual focus modes.

• AF Mode: Slide the switch to "AF". The lens will use the camera's autofocus system. The SMT stepping motor ensures fast and quiet focusing.
• MF Mode: Slide the switch to "MF". Rotate the focus ring on the lens to manually adjust focus.

Aperture Control

The lens offers both electronic aperture control via the camera and a physical stepless aperture ring.

• Camera Control: Ensure the aperture ring toggle switch on the lens is set to the "ON" position (or "A" for Auto). You can then control the aperture directly from your camera body.
• Manual Aperture Ring: Slide the aperture ring toggle switch to the "OFF" position (or a specific f-stop value). You can then rotate the aperture ring on the lens to adjust the aperture. The stepless design allows for smooth aperture changes, beneficial for video recording.

LCD Display

The integrated LCD display provides real-time information about the lens settings.

• The display shows the current aperture value and focus distance.
• This feature is particularly useful in low-light conditions or when precise focus information is needed.

Customizable Fn Buttons (Fn1 & Fn2)

The lens is equipped with two customizable function buttons.

• Fn1 Button: In AF mode, a short press can be customized for various camera functions (e.g., focus hold, depth-of-field preview). Refer to your camera's manual for customization options.
• Fn2 Button: In MF mode, a long press saves the current focus point. You can save two focus points (A and B) and switch between them with a short press. This is useful for precise, repeatable focus shifts.

Firmware Upgrades

The lens features a Type-C USB port for firmware upgrades. Visit the VILTROX official website for the latest firmware and instructions to ensure optimal performance and compatibility.

Maintenance

• Cleaning the Lens: Use a soft, lint-free cloth specifically designed for optical surfaces. For stubborn smudges, use a lens cleaning solution applied to the cloth, not directly to the lens.
• Dust and Moisture: While the lens is weather-sealed, avoid exposing it to excessive dust, dirt, or moisture. If it gets wet, wipe it dry immediately.
• Storage: When not in use, store the lens with both front and rear caps attached in a dry, cool place, away from direct sunlight and extreme temperatures. Consider using a desiccant to prevent mold growth in humid environments.
• Handling: Always handle the lens by its barrel, not by the front element or lens hood. Avoid dropping or subjecting the lens to strong impacts.
