Overview

The Canon RF-S 3.9mm F3.5 STM Dual Fisheye is a specialized lens for creating stereoscopic 3D 180° VR video on APS-C EOS R-series cameras like the R7. It offers a 144° angle of view and is more affordable than its full-frame sibling, the RF 5.2mm F2.8 L, due to a smaller aperture and APS-C compatibility. Optical strengths include immersive VR capture, but the F3.5 aperture is slower. Build and handling are streamlined for VR production. It suits creators seeking an entry point into VR content creation with existing Canon APS-C gear.
