STM Autofocusing Motor

The RF-S 7.8mm f/4 STM Dual VR lens is powered by a gear-type stepping motor (STM) with a dual-lens autofocus system, enabling the left and right lenses to move swiftly and quietly in sync. This setup makes autofocusing as intuitive as using a single standard lens. Suitable for both photography and video, the lens features an electronic focusing/control ring and a left-right focus difference adjustment switch, giving you the flexibility to focus both lenses together or just the left lens as needed. Compatible with Canon’s Dual Pixel CMOS AF, it also supports full-time manual focus for precise control, ideal for dynamic or action shots.

Design and Construction

This lens captures immersive content in Spatial, 3D 180°, and 3D formats, thanks to its straight-path optical system with two ultra-low dispersion elements that effectively minimize chromatic aberrations. With a construction of nine elements in five groups, it also features Canon's Super Spectra Coating to reduce ghosting and flare, ensuring clear and vibrant images. It accommodates light-modifying filters with a 58mm front thread, and its close 5.9" minimum focusing distance brings your subjects into sharp detail. Compact and lightweight, the lens extends just 1.6" from the camera and weighs a mere 4.6 oz, making it an ideal travel companion.

James ★★★★★

The dual-lens autofocus system locks onto subjects almost instantly, making it perfect for fast-moving kids or pets. Depth and clarity across both lenses feel perfectly matched, which is crucial for VR content.

Michael ★★★★★

The STM autofocus is impressively snappy, locking onto subjects in near silence. I was worried the dual-lens system might be gimmicky, but the depth effect in photos is genuinely noticeable and adds a unique look. It charges quickly too, ready to go in about 40 minutes.

Ella N. ★★★★★

I was skeptical about the dual-lens autofocus, but it locks onto subjects with impressive speed. The 7.8mm focal length gives a wonderfully wide perspective for tight indoor spaces. It’s become my go-to for architectural shots on my Canon body.
