Laowa Argus S35 Cine 18mm T1 - Canon RF

Laowa Argus S35 Cine 18mm T1 - Canon RF — Ultra-fast T1 for Super35 cinematography

The Laowa Argus S35 Cine 18mm T1 in Canon RF mount brings an ultra-fast T1 aperture to Super35 filmmaking. It offers filmmakers strong low-light capability and cinematic control over depth of field, while fitting into professional production workflows. The lens targets narrative filmmaking, commercials, documentaries, music videos, and other creative projects that require precise manual control and cinematic image character.

Outstanding low-light performance and cinematic control

With a maximum aperture of T1, this 18mm lens enables shooting in challenging light without relying heavily on additional illumination. Consequently, you can achieve shallow depth of field and clear subject separation. In addition, the lens uses a 9-blade iris to produce smooth, pleasing bokeh and refined focus transitions for cinematic looks.

Optical design for clarity and color fidelity

The Argus S35 Cine 18mm uses a 14-element, 9-group optical construction that includes specially selected elements. Therefore, it reduces chromatic aberration, distortion, and color fringing. As a result, you get consistently sharp images and accurate color reproduction across the frame, even when shooting wide open at T1.

Designed and built for professional cinematography

The lens features cine-style gearings and a uniform 80mm outer diameter to integrate easily with follow-focus systems and matte boxes. Additionally, the M77 front filter thread allows you to attach filters directly. Built from robust metal, the housing offers compact, professional-grade durability for both handheld and rig-based shooting.
