Canon RF-S 7.8mm f/4 STM Dual 7mm
A stereoscopic dual-lens design captures spatial video for Apple Vision Pro and Meta Quest 3, using an STM autofocus motor and a 60° field of view on APS-C bodies like the EOS R7. Its compact 130g build and f/4 constant aperture make it an accessible entry point into the Canon EOS VR System without heavy rigs. This lens is best for content creators experimenting with 3D vlogging and immersive video, not for traditional landscape or macro work.
