A Groundbreaking Dual Fisheye Lens for Immersive 3D Content
The Canon RF-S 3.9mm F3.5 STM Dual Fisheye Lens is an innovative, APS-C-format lens designed for Canon RF-mount mirrorless cameras, built for creators who want to capture realistic, three-dimensional VR-style content. Its dual fisheye design perfectly syncs left and right perspectives to create immersive 3D imagery, giving viewers the freedom to look around a scene while still following the focal point of the story.
A Truly Immersive Viewing Experience
This lens is made for storytellers who want to move beyond flat, traditional video and into fully immersive content. It offers a wide 144-degree angle of view from both lenses simultaneously, and its 60mm interpupillary distance closely resembles the spacing of human eyes, creating a genuinely realistic 3D viewing experience for audiences using VR headsets or 3D-capable displays. This makes it a compelling tool for documentary filmmakers, VR content creators, and anyone producing immersive storytelling experiences.
Optical Performance and Build
The optical design includes two Ultra-Low Dispersion glass elements to ensure high image quality and minimize aberrations across both fisheye perspectives. An Air Sphere Coating protects against flare and ghosting, helping maintain clarity and contrast even in challenging lighting. A built-in gelatin filter holder at the rear of the lens allows for creative filtration without needing front-mounted filters, which aren't possible on a fisheye design. The lens is compact, weighing approximately 290g, though it does not include dust or moisture-resistant sealing.
Fast, Convenient Autofocus
An STM autofocus motor delivers faster, smoother focusing, letting creators set up quickly and spend more time focused on the story rather than manual adjustments. A combined control and focus ring can be customized to another function, streamlining workflow for photographers and videographers who want quick access to key settings.
