Fixed focal-length. No zoom.
3D - Produces stereoscopic images that give the impression of 3D.

Manual Focus Only lens.Lens Description
The Canon RF-S 3.9mm F/3.5 STM Dual-Fisheye is an ultra-wide prime designed for cameras with a APS-C (1.6X) sensor. This prime has a 3.9mm focal-length. It provides the same field of view as a 6.24mm lens on a Full-Frame camera.
This prime lens focuses down to 20cm from the imaging plane, capturing subject with a maximum 0.03X magnification. The lens is not capable of autofocus and so the focus-distance must always be manually adjusted via the focus-ring. A built-in focus motor is used to set the focus-distance. It allowed Canon to optimize the motor precisely for this lens in order to maximize performance.
The lens weighs 290g.
This lens is only available for the Canon RF mount. It directly attaches and is fully compatible with all Canon RF mount cameras with APS-C (1.6X) sensors.
