VR lens for APS-C mirrorless cameras
The Canon RF-S 3.9mm f/3.5 STM Dual Fisheye is built for the EOS VR System and works exclusively with the EOS R7 running firmware 1.5 or later. It captures stereoscopic 3D 180-degree VR imagery on a single APS-C sensor, targeting creators who want immersive output without a multi-camera rig. The 144-degree field of view keeps tripods and microphones out of the frame during recording.
Mounts like a standard RF lens, focus is STM only
The lens attaches to the RF-S mount and uses a leadscrew-type stepping motor for autofocus, allowing pre-focus before filming. Servo AF is not available during video shooting, so focus must be set beforehand or adjusted manually. A rear 30.5mm screw-on filter thread and gel filter holder are provided, but there is no image stabilization built into the optic.
Single-file 180 VR on one sensor.
The folded optical design with two UD elements and Air Sphere Coating delivers a 144-degree capture that maps to 180-degree viewing in a single file, simplifying post-production. It comfortably handles immersive VR workflows on the EOS R7 but runs out of compatibility with any other current camera body. Buyers needing full-frame coverage or multi-camera flexibility cannot use this lens.

Questions about this item
How do I confirm the lens is capturing 144º stereoscopic VR correctly after mounting it on my EOS R7?
Attach the lens to an EOS R7 running firmware 1.5 or later, record a test clip, then review the single-file output in Canon's VR software to verify the 144º field of view renders as 180º 3D VR without visible tripod or microphone intrusion.
What accessories are included and which must be purchased separately for this RF-S 3.9mm f/3.5 STM Dual Fisheye lens?
The lens ships with front and rear caps; a 30.5mm screw-on filter or the rear gel-filter holder are optional purchases, and the EOS R7 camera plus Canon VR software are required but sold separately.
Should I choose this 3.9mm f/3.5 APS-C dual fisheye or the 5.2mm f/2.8 L full-frame version for my VR workflow?
Select the 3.9mm f/3.5 if you shoot with an EOS R7 or other APS-C RF body and want a lighter 0.64 lb lens; choose the 5.2mm f/2.8 L for full-frame EOS R cameras when you need the wider f/2.8 aperture and L-series build.
