The Canon RF-S 7.8mm f/4 STM Dual Lens is a user-friendly stereoscopic VR lens designed for the Canon EOS VR System, perfect for turning everyday moments into augmented reality. This lens is compatible with APS-C EOS mirrorless cameras such as the EOS R7 and boasts a 60° field of view similar to human vision. It produces high-quality photos and videos that can be viewed on popular headsets like the Apple Vision Pro and the Meta Quest 3. STM Autofocusing MotorDriving the RF-S 7.8mm f/4 STM Dual VR lens is a gear-type stepping motor (STM) with a dual-lens autofocus mechanism, which drives the left and right lenses quickly, quietly, and in unison. This makes autofocus as simple to operate as it is with an ordinary lens. Available for both photo and video, the electronic focusing/control ring and the left-right focus difference adjustment switch allow the option to control focus on both lenses or the left lens only. The lens is compatible with Canon's Dual Pixel CMOS AF autofocus system, and full-time manual focus is also supported.Design and ConstructionThe lens creates content in Spatial, 3D 180°, and 3D formats with a straight path optical system that features two ultra-low dispersion elements to suppress chromatic aberrations. With nine total elements in five groups, the lens sports Canon's Super Spectra Coating to reduce ghosting and flare. The lens supports light-modifying filters with a 58mm front thread, and the 15cm minimum focusing distance means your whole world is rendered sharply. The lens is compact and lightweight, extending only 4cm from the camera and weighing only 131g.
