Laowa Argus S35 Cine 25mm T1 - Canon RF

The Laowa Argus S35 25mm T1 Cine for Canon RF-mount is a professional standard prime that combines a natural perspective with an incredibly fast T1 aperture. Designed for Super35 and APS-C sensors, it provides an approximately 37.5mm full-frame equivalent focal length—the classic "storyteller's" view. This lens is a powerhouse for narrative filmmaking, offering the ability to shoot in extreme low light while achieving a level of subject isolation and buttery background blur that defines high-end cinematography.

Housed in a precision-engineered cine body, the lens features minimal focus breathing, ensuring your frame remains stable during dramatic focus pulls. With a 250° focus throw, it provides the granular control necessary to manage the razor-thin depth of field at T1, making it a reliable companion for professional focus pullers and solo operators alike.

Product Features in Detail

Cinematic Low-Light Mastery
The T1 aperture allows you to maintain clean, low-noise footage in environments that would typically require heavy lighting rigs. This is essential for indie filmmakers and documentary crews shooting in available light, ensuring the sensor captures rich colors and deep shadows without excessive ISO grain.

The "Natural" Storytelling Focal Length
The 25mm focal length on S35 sensors provides a perspective very close to the human eye. It is wide enough to capture the environment but tight enough to prevent the facial distortion often found in wider lenses, making it the perfect choice for dialogue-driven scenes and character studies.

Precision Focus Pulling
With a 250° rotation angle, the focus ring is designed for the professional 1st AC. This long throw allows for smooth, slow focus racks that feel natural and cinematic, ensuring that your critical focus stays exactly where it needs to be during complex character movements.

Standardized Workflow
The 80mm outer diameter and M77 filter thread are consistent with other Argus S35 cine lenses. This "matched" design saves valuable time on set, as you won't need to re-adjust your matte box, wireless motors, or filter kits when swapping between different focal lengths in the series.

Dynamic Close-Up Performance
A minimum focus distance of 13.4" allows you to move in for intimate close-ups. When combined with the T1 aperture, the background doesn't just blur—it melts away—allowing you to guide the audience's attention to the smallest emotional details or product textures.

Built for the Rigors of Production
The lens features a rugged, all-metal housing and a removable lens support thread. This ensures the lens remains rock-solid on your camera rig, even when using high-torque wireless focus motors or shooting in high-vibration environments like car-mounted setups.
