Canon RF-S Dual Fisheye Lens
The Canon RF-S 3.9mm f/3.5 STM Dual Fisheye Lens captures immersive stereoscopic 3D 180° VR content. It is designed specifically for the EOS R7 mirrorless camera and suits creators producing virtual reality experiences. The bundle includes a Pro Sling Backpack, lens cap keeper, and cleaning kit.
6.2mm Full-Frame Equivalent Focal Length
This lens provides a 6.2mm full-frame equivalent focal length and a 144° field of view, which determines the spatial coverage for VR capture. The fixed 3.9mm focal length and f/3.5 maximum aperture define the optical perspective. It is not suited for standard photography or flat video production requiring variable zoom.
f/3.5 to f/16 Aperture Range
The aperture range of f/3.5 to f/16 handles diverse lighting conditions while maintaining depth for VR scenes. The 7-blade diaphragm contributes to smooth background rendering. The 30.5mm rear filter thread allows filter use for creative control. The APS-C design limits coverage to crop-sensor cameras and cannot fill a full-frame image circle.

Questions about this item
What does the 144° field of view actually give me on an EOS R7?
On the EOS R7 the dual fisheye produces a 144° stereoscopic view that records immersive 180° VR footage, placing the viewer inside the scene with natural depth perception.
How does the RF-S mount affect what cameras I can use this lens on?
The RF-S mount fits APS-C EOS R bodies such as the R7; it will not mount on full-frame RF cameras without crop mode, and it cannot be adapted to EF or other systems.
What does the 30.5 mm rear filter thread mean for mounting and accessories?
A 30.5 mm thread at the rear accepts standard screw-in filters so you can add ND or protective glass without a bulky front holder, keeping the rig compact for VR rigs.
