Canon RF-S 3.9 mm F3.5 STM DUAL FISHEYE Lens

FULL DESCRIPTION

The Canon RF-S 3.9 mm F3.5 STM DUAL FISHEYE is a cutting-edge lens designed for creating immersive VR180 3D content. With dual 3.9mm fisheye lenses and a 60 mm interpupillary distance, it replicates natural human stereo vision for a highly engaging visual experience. Tailored for Canon’s APS-C mirrorless EOS R series (e.g., EOS R7), this lens captures both left and right images on a single sensor, supporting up to 4K 30 fps recording. The Air Sphere Coating (ASC) minimizes flare and ghosting, while UD elements reduce chromatic aberrations for sharp, high-contrast results.
