Canon RF-S 7.8mm F/4 STM Dual Lens

A Compact Stereoscopic Lens for Realistic 3D Content

The Canon RF-S 7.8mm F4 STM Dual Lens is a stereoscopic RF VR lens designed for APS-C-format Canon RF-mount mirrorless cameras, built for creators who want to produce genuinely immersive 3D content in a small, easy-to-carry package. Its dual-lens design merges two separate images into a center-projection 3D image, offering a realistic viewing angle well-suited to close-range, human-scale storytelling.

A Compact Design for Practical VR Content Creation

This lens is made for creators who want stereoscopic capture without a bulky, specialized rig. Its 7.8mm focal length and 63-degree field of view deliver a realistic, natural-feeling viewing angle, while its 11.8mm baseline length is tuned for close-range subjects and intimate scenes. Weighing just 130g and measuring a compact 69.2mm x 41.5mm in its retracted state, it's designed to be practical and interchangeable, easily fitting into a creator's existing kit.

Optical Performance and Build

The optical design includes two Ultra-Low Dispersion glass elements to help prevent flare, ghosting, and aberrations across both lenses, keeping images clear and consistent for a comfortable 3D viewing experience. A Super Spectra coating further improves contrast and color accuracy. The lens has an optimum shooting distance of 0.15m to 0.5m, making it particularly well-suited to close-up, tabletop, and personal-scale VR content rather than distant scenes.

Simple, Reliable Autofocus

An STM autofocus motor focuses quickly on the subject, allowing for easy operation and faster setup so creators can spend less time adjusting and more time filming. A combined control and focus ring allows simple calibration between the two lenses, while a standard 58mm front filter thread accepts neutral density filters for shooting in bright outdoor conditions.
