Samyang V-AF 45mm T1.9 Sony FE

Samyang V-AF 45mm T1.9 Sony FE – 8K-capable, small and lightweight cinema lens

The Samyang V-AF 45mm T1.9 for Sony FE is a cinema lens designed for modern video production. It supports resolutions up to 8K and comes in a small, lightweight form that suits handheld gimbals, drones, studio setups and location shoots. The lens belongs to Samyang’s V-AF series, which shares a unified form factor across the lineup.

Designed for consistent workflow and easy rigging

The V-AF series uses a uniform weight and size across its focal lengths. As a result, you do not need to rebalance stabilizers and gimbals when swapping lenses in the same series. This consistent form factor also simplifies use with drones and camera rigs for location work.

Controls and customization on the lens body

The V-AF 45mm includes practical controls for video shooters. On the lens front you will find a tally lamp that indicates when the camera is recording. This feature can be particularly useful for content creators, including YouTubers.

On the lens side there is a customizable dial. You can set this dial to enable manual focus or to allow aperture adjustment by turning the focus ring. Below the dial sits a focus hold button, which locks focus at a chosen distance. Additionally, users can assign other functions to the slider via firmware updates, giving flexibility for different shooting needs.

Autofocus, focus feel and optical design

Autofocus on the V-AF 45mm is driven by Samyang’s linear STM focus motor. This motor provides quiet and smooth autofocus operation while minimizing vibration and noise during recording.

The lens optical construction consists of 10 elements in 8 groups, including 2 ASP (aspherical) and 2 HR (high refractive) elements. These special elements help deliver a crisp, cinematic look. The 9-bladed circular aperture produces a smooth bokeh and a blurred background that helps subjects stand out with depth and dimensional impact.

Use cases

• Handheld gimbals — the small, lightweight design reduces the need for rebalancing between lenses from the same series.
• Drones — uniform size and weight across the series make lens swaps simpler during aerial shoots.
• Studio and location productions — color-matched lenses avoid visible shifts when changing focal lengths during a shoot.
• Content creators — the front tally lamp shows recording status, a practical feature for solo setups and small crews.
