Laowa Argus S35 Cine 25mm T1 - Canon RF

Laowa Argus S35 Cine 25mm T1 — Canon RF mount with ultra-fast T1 aperture for Super35

The Laowa Argus S35 Cine 25mm T1 in Canon RF mount gives filmmakers a fast, cine-oriented lens built for Super35 camera systems. With a maximum aperture of T1, it performs well in low-light situations and offers cinematic depth-of-field control. The lens pairs a compact, professional metal housing with cinema-friendly features to support both handheld and rig-based shooting.

Low-light performance and cinematic control

The ultra-fast T1 maximum aperture lets you capture scenes with minimal additional lighting. Consequently, you can rely on the large aperture to achieve shallower depth of field, stronger subject separation, and smoother focus transitions. Moreover, the lens uses a 9-blade iris that helps produce pleasing, film-style bokeh for creative looks.

Optical construction and image quality

The Argus S35 Cine 25mm uses a detailed optical formula consisting of 14 elements arranged in 9 groups. This construction includes special elements that reduce chromatic aberration, distortion, and color fringing. As a result, the lens delivers sharp, color-accurate images across the frame, even when used wide open at T1.

Design for professional cinema workflows

Laowa built the Argus S35 Cine T1 series for professional cinematography. The lenses feature industry-standard cine-style gearings and a uniform 80mm outer diameter, which simplifies integration with follow-focus systems and lens accessories. Additionally, the M77 front filter thread supports matte boxes and filters for practical on-set use. The rugged metal housing ensures durable, precise handling during demanding productions.
