Sirui 40mm T1.8 1.33x S35 AF Anamorphic Lens (Neutral Flares)

Cinematic Storytelling, Reimagined for Mirrorless Creators
Step into the world of widescreen cinema with the Sirui 40mm T1.8 1.33x S35 AF Anamorphic Lens—a compact yet powerful optical tool built for storytellers who demand more than ordinary. With its 1.33x squeeze factor and a Super35 coverage, this lens delivers a signature anamorphic look with breathtaking neutral flares, expansive aspect ratios, and oval bokeh that transforms any scene into a visually compelling narrative. Designed for mirrorless shooters, it's a game-changer for indie filmmakers, commercial directors, and content creators looking to elevate their visual language.

Smooth Autofocus Meets Precision Manual Control
One of the most common frustrations in anamorphic filmmaking is the difficulty of achieving precise focus—especially for run-and-gun shooters. The Sirui 40mm T1.8 AF solves this challenge with a fast, responsive autofocus system paired with a wide T1.8 aperture for stunning low-light performance and razor-thin depth of field. This combination offers flexibility for dynamic handheld work while still supporting manual control when precision is essential. Whether you're chasing fleeting light or capturing carefully composed frames, this lens helps you lock focus with confidence.

True Anamorphic Look Without the Hollywood Price Tag
Professional anamorphic glass has long been out of reach for many creators due to size, price, and complex workflows. The Sirui 40mm answers this pain point with a lightweight, affordable, and adaptable build. It gives your footage that distinctive 2.4:1 cinematic aspect ratio without expensive post-processing or plugins. The neutral flare design keeps your colors clean while still adding just enough visual character to separate your work from standard spherical lenses. It’s ideal for brand videos, music visuals, and indie features where style meets substance.

Built to Fit Modern Shooting Styles
Unlike traditional anamorphic lenses that are bulky and unwieldy, the Sirui 40mm T1.8 AF is designed with portability in mind. Compact enough to fit comfortably on a gimbal or handheld rig, it supports fast-paced production environments without compromising quality. Its durable metal construction is built to withstand demanding shoots, while the autofocus functionality makes it compatible with hybrid workflows—perfect for creators transitioning between stills and motion. It’s an ideal choice for travel filmmakers, event videographers, and studio operators alike.

Flexible Compatibility and Future-Proof Format
Another frustration for buyers is lens obsolescence—systems that work beautifully for one camera setup but fail to adapt to future gear. Sirui designed this lens to be future-ready, with interchangeable mounts and native autofocus support on leading mirrorless platforms (check compatibility before purchase). Its Super35 coverage pairs well with APS-C sensors, delivering high-resolution images and maximizing every pixel. This makes it an excellent investment for creators who want a lens that evolves with their kit.
