Sirui 20mm T1.8 1.33x S35 AF Anamorphic Lens (Neutral Flares)

Widen Your World: Ultra-Wide Anamorphic Cinematics
The Sirui 20mm T1.8 1.33x S35 AF Anamorphic Lens opens up an entirely new visual dimension for storytellers. With a dramatic 20mm focal length on Super35 sensors, this lens captures expansive scenes with unmistakable anamorphic character—wide horizontal stretch, soft oval bokeh, and clean neutral flares. It's perfect for immersive cityscapes, dynamic action shots, or tight indoor locations where space is limited but vision is boundless.

By compressing more visual information into the frame, this lens lets you tell more of the story—without needing to back up or crop. This is ideal for YouTubers, filmmakers, and commercial shooters who want cinematic impact in challenging or tight environments.

Cinematic Look, Made Simple and Affordable
One of the biggest frustrations creators face is how hard it is to achieve the anamorphic look without expensive, bulky gear or complex post workflows. Sirui solves this by offering an affordable, lightweight, and native anamorphic lens that produces a beautiful 2.4:1 aspect ratio with zero plugins and minimal post-processing.

The neutral flares give your shots a more natural, polished aesthetic compared to traditional blue streaks—making it perfect for commercial work, interviews, or color-sensitive projects. You’ll capture that stylized cinematic feeling, but with restraint and elegance.

Fast Autofocus, Real-Time Control
Traditional anamorphic lenses often require full manual focus, which can be overwhelming for solo shooters or run-and-gun filmmakers. The Sirui 20mm T1.8 changes the game by incorporating autofocus capabilities—something nearly unheard of in this lens category.

Combined with a fast T1.8 aperture, you get exceptional low-light performance and stunning subject separation. Whether you’re shooting wide open for dramatic depth or pulling focus in fast-paced environments, this lens gives you the speed and control you need—with a fraction of the effort.

Compact Build, Built for Motion
Another frequent pain point is gear bulk—especially for those working with gimbals, drones, or handheld rigs. Many anamorphic lenses are simply too heavy or long for mobile use. Not this one.

With its compact and lightweight design, the Sirui 20mm T1.8 is ideal for filmmakers on the move. It mounts comfortably on mirrorless cameras and balances beautifully on stabilization systems. Whether you’re running through streets or flying above landscapes, you’ll enjoy consistent performance and smooth integration into your setup.

Flexible Mounts and Super35 Compatibility
Worried about future-proofing your gear? The Sirui 20mm offers interchangeable mirrorless mounts—including Sony E, Canon RF, Nikon Z, and Fuji X—ensuring it works seamlessly with today’s leading cameras. Optimized for Super35 and APS-C sensors, it gives you edge-to-edge clarity and cinematic scale, without the cost or complexity of full-frame anamorphic lenses.

It’s the smart choice for creators who want a lens that fits their workflow today—and grows with them tomorrow.

Why You Should Use This Product
