Canon RF-S 3.9mm f/3.5 STM Dual Fisheye Lens Overview

The Canon RF-S 3.9mm f/3.5 STM Dual Fisheye Lens is an innovative VR lens designed specifically for Canon APS-C EOS R mirrorless cameras. Engineered for immersive VR180 content creation, it features two synchronized fisheye optical systems that capture stereoscopic 3D images and video onto a single image sensor. This greatly simplifies VR production compared to traditional dual-camera setups while delivering high-quality immersive footage. The lens is optimized for Canon's EOS VR System and is compatible with supported cameras such as the EOS R7 and EOS R50 V. 

Each optical path incorporates two Ultra-Low Dispersion (UD) elements and Canon's Air Sphere Coating (ASC) to reduce chromatic aberrations, flare, and ghosting while maintaining outstanding image quality. The gear-type STM autofocus system allows smooth and quiet focusing, while the compact 290g design makes it easy to carry for professional VR productions, virtual tours, immersive storytelling, education, tourism, and content creation.
