Canon RF-S 3.9mm F3.5 Dual Fisheye STM Lens

Canon RF-S 3.9mm F3.5 Dual Fisheye STM: 180° VR Capture for APS-C EOS R Bodies

A prime camera lens for Canon RF mount with an F3.5 maximum aperture, 6mm equivalent on an APS-C body, weighing 290 (without rear filter holder attached)g. It is weather sealed, and built to resolve the detail of Canon's latest sensors.

Who Is This Made For?

The RF-S 3.9mm F3.5 Dual Fisheye STM is for creators making immersive VR and 3D content for headsets and spatial video platforms, using a single EOS R body. It is small enough to leave on the camera all day, and its compact design keeps the kit light.

Optics Designed for High-Resolution Sensors

The RF-S 3.9mm F3.5 Dual Fisheye STM uses 11 elements in 8 groups. Aspherical and UD elements keep edges sharp and colour fringing low, and Super Spectra coatings control flare and ghosting. The diagonal angle of view is 144°00′.

Two Lenses, One Sensor, Instant 3D

Twin fisheye optics project a stereoscopic pair onto a single sensor, so VR and 3D content is captured in one file with perfect sync and no rig. Canon's EOS VR Utility and plug-ins convert the footage for headsets and spatial video platforms.

Compact Design, Consistent Rendering

The F3.5 maximum aperture and 7-blade circular diaphragm produce smooth background blur and clean specular highlights. The RF control ring can be assigned to aperture, ISO or exposure compensation for direct control. Minimum aperture is F16.

Fast, Quiet Autofocus

A stepping motor delivers smooth, quiet autofocus suited to stills and video. Closest focus is 0.2m with a maximum magnification of 0.03xx.

Weather Sealed

The lens is sealed against dust and moisture. It measures 112.0 × 83.7 (height) x 54.6mm and weighs approximately 290 (without rear filter holder attached)g, and uses a rear gel filter holder.
