Create more immersive stories with the RF-S 3.9mm f/3.5 STM Dual Fisheye Lens from Canon. Designed for the EOS R7 APS-C mirrorless camera system, a full-frame equivalence of 6.2mm is provided. The dual high-performance fisheye lenses allow you to capture stereoscopic 3D 180° VR imagery with a 144° field of view to a single image sensor, simplifying your workflow and saving you time in post. Pairing this lens with the EOS R7 allows recordings up to 4K 30 fps. Autofocus is available when capturing stills via a gear-type STM motor.

STM Autofocusing Motor
Driving the RF-S 3.9mm f/3.5 STM Dual Fisheye is a gear-type stepping motor (STM) with a dual-lens autofocus mechanism, which drives the left and right lenses in unison. This makes autofocus as simple to operate as it is with an ordinary lens. The electronic focusing/control ring and the left-right focus difference adjustment switch enhance operation by allowing adjustment of the left-right focus differential.

Autofocus operates only on subjects within the image circle of the left lens. Additionally, Servo AF is not available. Before shooting a movie, users must adjust the focus to One-Shot AF or manual focus.

Portable and Lightweight Design
The RF mount and the folded optical design allow for a compactl lens design that's easy to use in tight spaces. Weighing just 10.2oz, this dual fisheye lens conveniently fits in most bags and is perfect for travel.
Air Sphere Coating (ASC)
Ghosting and reflections are noticeably reduced by Canon's air sphere lens coating. During challenging lighting conditions, such as backlit scenes, more contrast and uniform colors are present in your images.
30.5mm Rear Filter Thread
Designed to support filters, 30.5mm screw-on filters can be attached to the rear of the lens, as well as a filter holder for cut gel and polyester filters.

Asked by: Philipp
The Canon RF-S 3.9mm f/3.5 STM Dual Fisheye Lens (Canon RF) currently is only supported when using Canon Cameras made for the lens like the Canon R7. While the lens may mount on the RED Komodo it has not been tested or would it have a workflow for generating 3D content at this time when using the Canon lens.
