Samyang V-AF MF Adapter

Samyang V-AF MF Adapter – Manual focus control with smooth 300° rotation and 95mm front for matte boxes

The Samyang V-AF MF Adapter attaches to the front bayonet mount of any V-AF lens and gives filmmakers and videographers direct, mechanical control over focus. It converts the lens into a manual-focus tool that supports traditional cinema workflows and accessory compatibility.

Compatibility and purpose

The adapter fits V-AF lenses that have a front bayonet mount. By mounting the adapter, you gain precise manual focus control even when your subject moves. Many videographers prefer manual focus for fast-moving sequences because they can decide exactly where the lens focuses instead of relying on the camera’s autofocus.

Focus control and mechanics

The focus ring features an industry-standard 0.8 mod, so you can pair the adapter with any follow focus system designed to that standard. In addition, the adapter offers a smooth 300° rotation for fine focus adjustments, allowing for precise pulls and repeatable focus marks.

It also includes a dual distance scale marked in both feet and meters. Therefore, you can read focus distances in the unit you prefer and make quick, accurate changes on set. The adapter operates mechanically, providing tactile feedback and reliable manual control without electronic dependency.

Additional features for production workflow

When attached, the MF ring on the lens side can be used as an aperture ring, giving you straightforward control over exposure without changing lens handling. A built-in tally lamp on the front of the adapter indicates whether the camera is recording or in standby, which helps inform both the subject and the crew.

The adapter has a 95mm front diameter. This standard size makes it easy to attach matte boxes and other front-mounted accessories commonly used in cinema production.

Size and weight advantage

Cinema lenses are often heavy and bulky. By using the Samyang V-AF MF Adapter together with a V-AF Series lens, you retain many features of a conventional cinema lens while keeping the overall package compact. In combination with a V-AF Series lens, the total weight is 430 g, which is roughly half the typical weight of a conventional cinema lens.
