Canon RF-S RF-S7.8mm F4 STM Dual 8mm
This stereoscopic lens stands out with its 7.8mm f/4 dual-lens design, delivering a 60° human-vision-like field of view for spatial video on APS-C cameras at just 131g. Combined with STM autofocus and a control ring, it provides steady handheld capture without adding bulk, lowering the barrier to Canon’s EOS VR System. It’s best for vloggers and social media creators wanting to capture immersive 3D memories viewable on the Apple Vision Pro or Meta Quest 3.
