Product details

The Canon RF-S 3.9mm F3.5 STM Dual Fisheye has been designed to enable more content creators to produce immersive, high-quality 3D VR content, even if they are just beginning their journey into virtual reality.

With a wide field of view of 144 degrees and a 60 mm distance between the lenses, it captures what the human eye sees, allowing the audience to dive even deeper into the experience. The large depth of field ensures a natural-looking image, providing a particularly lifelike experience.

This dual fisheye lens with reliable autofocus adds three-dimensional depth to stories and makes the setup for recording especially easy. Perfectly aligned, synchronized, and focused.

The excellent image quality is achieved through the high-quality ASC coating (Air Sphere Coating) and UD lenses, which prevent stray light, ghosting, and optical aberrations. The aperture of 1:3.5 allows for dependable shots both indoors and outdoors.

With the switchable lens control/focus ring, as well as the screw and film filter holder, any desired look can be achieved. The possibilities for creativity are limitless.
