Viltrox AF 16mm f/1.8 Lens (L-Mount)

Overview

The Viltrox AF 16mm f/1.8 Lens (L-Mount) is a high-resolution ultrawide prime designed for full-frame L-mount cameras. With its expansive 105.6° angle of view and bright f/1.8 maximum aperture, it excels in landscape, architecture, astrophotography, and creative video applications that demand dramatic perspectives and strong low-light performance.

Combining advanced optics with intelligent design features, this lens delivers exceptional edge-to-edge sharpness, smooth bokeh, and professional-grade handling in a durable, weather-resistant all-metal body.

Core Features

• Full-frame 16mm ultrawide prime with bright f/1.8 maximum aperture for low-light shooting and shallow depth-of-field control.
• Advanced optical design with 4 ED and 3 aspherical elements to reduce aberrations, coma, ghosting, and flare.
• Fast and quiet STM autofocus motor suitable for both stills and video applications.
• Silent stepless aperture ring with click/de-click switch for smooth exposure transitions in video.
• Integrated LCD screen displays object distance, aperture information, and function indicators.
• Durable all-metal construction with brass mount and dust- and water-resistant design.
• USB-C interface enables convenient firmware updates.
• Compatible with widely available 77 mm front filters.

Optical Performance

Engineered as a large-aperture, high-resolution prime, the lens delivers impressive sharpness across the entire frame. The inclusion of 4 extra-low dispersion elements and 3 aspherical elements effectively controls chromatic aberration and distortion while reducing sagittal coma flare—ideal for preserving the natural shape of stars in astrophotography.

HD Nano multilayer coating further minimizes ghosting and flare, ensuring strong contrast and clarity when shooting in challenging lighting conditions such as night scenes and long exposures.

Video-Friendly Controls

Designed with hybrid creators in mind, the lens features an aperture switch that enables clicked or de-clicked operation. In stepless mode, aperture adjustments are smooth and silent, making it ideal for professional video production.

The fast and near-silent STM autofocus system supports accurate focus transitions, while dedicated Fn1 and Fn2 buttons allow quick access to customizable functions on select L-mount cameras.

Design & Durability

The all-metal barrel construction and brass bayonet mount provide a secure and reliable connection to L-mount camera bodies. Its dust- and water-resistant design allows confident use in outdoor and adverse weather conditions.

A built-in AF/MF switch allows rapid switching between focus modes, and the integrated LCD screen provides real-time shooting information at a glance. Despite its robust build, the lens remains well balanced at approximately 10.3 cm in length and 550 g in weight.
