Laowa Argus FF Cine 45mm T1 - Canon RF

Laowa Argus FF Cine 45mm T1 (Canon RF) – Ultra-fast T1 aperture for exceptional low-light cinematic imaging

The Laowa Argus FF Cine 45mm T1 in Canon RF mount brings the Argus FF Cine series' ultra-bright T1 aperture to full-frame cinema cameras with Canon RF mounts. It delivers the low-light performance and depth-of-field control expected from the Argus FF Cine lineup while integrating cinema-style ergonomics for professional rigging and manual control.

Designed for cinematic image quality and manual control

This 45mm T1 variant preserves the Argus FF Cine series’ optical philosophy. It uses premium optical elements, including Extra-Low Dispersion (ED) glass and aspherical elements, to reduce chromatic aberration, distortion, and color fringing. As a result, images remain sharp and true-to-life across the frame, even when shooting wide open at T1.

Moreover, the lens offers pronounced depth-of-field control and smooth focus fall-off, producing cinematic bokeh that helps subjects separate from expressive backgrounds. Because the lens features industry-standard cine-style gearings and a robust metal housing, it integrates easily with follow-focus systems, matte boxes, and other professional accessories.
