Canon RF-S 3.9mm f/3.5 STM Dual Fisheye Lens

Capture stunning stories with Canon's RF-S 3.9mm f/3.5 STM Dual Fisheye Lens. Specifically designed for the EOS R7 APS-C mirrorless camera system, it offers a full-frame equivalence of 6.2mm. The dual high-performance fisheye lenses enable you to shoot stereoscopic 3D 180° VR imagery with a 144° field of view, all to a single image sensor. This feature simplifies your workflow and saves time in post-production. Combined with the EOS R7, you can record in up to 4K at 30 fps. Autofocus is available for 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 colours 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.
