Laowa Ranger S35 17-50mm T2.9 Cine Lens - Arri PL, Constant T2.9 for Consistent Exposure

The Laowa Ranger S35 17-50mm T2.9 is a Super 35 cine zoom built for professional filmmaking. It offers a constant T2.9 aperture across the zoom range and arrives in an Arri PL mount configuration. Cinematographers can rely on consistent exposure and manual control for a range of narrative, commercial, and documentary production needs.

Parfocal Zoom and Optical Design

This lens uses a parfocal design, so focus holds steady while you zoom. As a result, you can execute smooth zooms and complex camera moves without needing to refocus constantly. In addition, the optical construction includes aspherical and low-dispersion elements. These elements help reduce chromatic aberration, distortion, and color fringing, producing sharper, higher-contrast images with accurate color reproduction and a pleasing focus roll-off even at wide apertures.

Handling, Build and Gearings

The Ranger S35 17-50mm is described as lightweight yet durable, making it suitable for handheld shooting, gimbal work, and use on professional cine rigs. It features cine-style focus and aperture gearings, so you can attach follow-focus systems and make precise manual adjustments during takes. Moreover, the series maintains a consistent front diameter and unified gear positioning to streamline lens swaps and reduce downtime on set.

Compatibility and Mount System

This model comes with an Arri PL mount. In the Ranger S35 series, lenses use an interchangeable mount system that allows adaptation to different camera platforms when needed. Therefore, the series can integrate into multi-camera environments and varied production workflows.
