Samyang V-AF 20mm T1.9 Sony FE – 8K-ready compact cine lens with a unified form factor

The Samyang V-AF 20mm T1.9 for Sony FE is a compact cinema lens designed for Sony E-mount systems. It supports resolutions up to 8K while remaining small and lightweight, which makes it well suited for handheld gimbals, drones, studios and location productions.

Design and series consistency

Samyang built the V-AF series with a unified form factor. Every lens in the line shares the same weight and size, which helps you work faster on set. Because the lenses are consistent, you do not need to rebalance accessories such as gimbals or drones when swapping lenses, saving time during shoots.

The V-AF line-up includes the following focal lengths: 20mm T1.9, 24mm T1.9, 35mm T1.9, 45mm T1.9, 75mm T1.9 and 100mm T2.3. All lenses in the series are color-matched to prevent color shifts when changing lenses.

Built for video workflows

The V-AF 20mm T1.9 offers features tailored to filmmakers. A tally lamp on the front of the lens indicates when the camera is recording, a useful feature for vloggers and YouTubers. Gear cogs are integrated for follow focus systems, and the lens delivers smooth focus rotation for precise manual control.

Controls and customization

On the side of the lens you will find a customizable dial. You can set this dial to operate manual focus or to allow aperture adjustment by turning the focus ring. Below this dial is a focus hold button that locks focus at a chosen distance. In addition, the slider can be reassigned to other functions via firmware updates, giving you flexibility for different shooting setups.

Optical and motor performance

The V-AF 20mm T1.9 uses an advanced lens construction aimed at delivering a crisp, cinematic look. Autofocus is driven by Samyang’s linear STM focus motor, which provides quiet, smooth autofocus while minimizing vibration and noise. The lens also uses a 9-bladed circular aperture to create smooth bokeh and a blurred background, helping subjects stand out with dimensional impact.
