The RF7-14mm f/2.8-3.5L Fisheye STM is a fisheye zoom lens that can capture 180° diagonal fisheye images on both full-frame and APS-C cameras. With a wide end of 7mm, it also achieves a unique 190° circular fisheye effect when used with a full-frame camera, capturing an angle of view that is wider than possible on any ultra-wide-angle lens.

What makes it different is that it supports autofocusing (AF) during both photo and video shooting. As a professional-grade L-series lens, it also realises exceptional image clarity and resolution, incorporating five UD lenses and two aspherical lenses to correct various aberrations and minimise colour bleeding. Filters are supported via a rear drop-in filter slot.

All these features are packed into a lightweight and compact body that weighs just approximately 476g—just as suitable for drones and gimbals as it is for handheld shooting. You can use it to capture landscapes, starscapes, architecture, events, or even street scenes from a new, unique perspective.

Fisheye lenses can capture an extremely wide angle of view because they use a different method to project images onto the image sensor compared to ordinary rectilinear (non-fisheye) lenses. A fisheye lens will capture more of a scene than a rectilinear lens with the same focal length.

At approximately 180° or more, the RF7-14mm f/2.8-3.5L Fisheye STM covers much more than what human eyes, including peripheral vision, can see. It’s what you need if you want to capture the sweeping scenery around you in just one frame—and it does so with a unique, ultra-dynamic exaggerated perspective.

Fisheye lenses capture a wider field of view than a normal lens with the same focal length because they use a different projection method. While RF7-14mm f/2.8-3.5L Fisheye STM is a zoom lens with a focal range of 7 to 14mm, the image circle it projects onto the sensor captures an angle of view of around 180° regardless of the focal length in use. It’s just that the image circle gets bigger when you zoom in!

The relationship between focal length, sensor size, and angle of view

On a full-frame camera

At 7mm on a full-frame camera, the lens projects an image circle that fits completely inside the image sensor. This creates a glass ball-like circular image with a 190° angle of view.
When you zoom in to 14mm, the image circle expands to cover the entire image sensor. The result: a diagonal fisheye effect with a 180° angle of view.

On an APS-C camera

On an APS-C camera, the RF7-14mm f/2.8-3.5L Fisheye STM’s image circle covers the entire sensor at focal length 8.7mm. This creates a diagonal fisheye effect with a 180° angle of view.

As the RF7-14mm f/2.8-3.5L Fisheye STM’s image circle doesn’t completely cover an APS-C sensor at focal lengths shorter than 8.7mm, there will be dark vignetting in the corners. The RF7-14mm f/2.8-3.5L Fisheye STM has a zoom limit switch to keep your zoom range within 8.7mm to 14mm, so you can avoid the focal lengths that cause vignetting.

With its maximum aperture range of f/2.8 to f/3.5, the RF7-14mm f/2.8-3.5L Fisheye STM has a larger maximum aperture than its f/4 EF counterpart regardless of the focal length you’re using. It incorporates two replica aspherical lens elements to counteract the aberrations that tend to occur with large aperture lenses, ensuring that the larger maximum aperture is accompanied by impeccable corner-to-corner image quality.

Five UD (Ultra low dispersion) lens elements in optimal placements further correct chromatic aberrations across the entire zoom range, achieving clean and clear images with minimal colour bleeding.

The RF7-14mm f/2.8-3.5L Fisheye STM’s f/2.8 maximum aperture also allows you to use a shutter speed one stop faster than the EF8-15mm f/4L Fisheye USM under the same lighting conditions. This is an advantage when you want to capture stars as point light sources before they trail.

Special coatings to prevent flaring and ghosting

A huge angle of view like that of the RF7-14mm f/2.8-3.5L Fisheye STM’s increases the chances of a strong light source ending up in your frame, whether it’s the sun when you’re shooting outdoors in the daytime, or artificial light sources like street lamps when you’re shooting at night.  This can cause ghosting and flaring, which lower contrast and obscure detail.

The RF7-14mm f/2.8-3.5L Fisheye STM effectively counteracts ghosting and flaring and minimises their occurrence by using anti-reflective ASC (Air Sphere Coating) on three highly curved optical glass surfaces.

The RF7-14mm f/2.8-3.5L Fisheye STM’s autofocus support makes it stand out among a sea of mostly manual focus fisheye lenses. Swift and accurate during still shooting, it also tracks subjects tenaciously during video shooting. Forget countless retakes: it will be a breeze to nail that stunning, dynamic shot of your subject in action.

The RF7-14mm f/2.8-3.5L Fisheye STM drives focus with a lead-screw type STM (stepping motor), which is highly responsive and enables more precise control. Startup times are further shortened by using a position detecting sensor traditionally used with the Nano USM. This results in fast and accurate autofocus during still shooting, and smooth and quiet AF tracking during video shooting.

Focus breathing correction is built into the optics: the RF7-14mm f/2.8-3.5L Fisheye STM adopts a rear focusing mechanism that minimises fluctuations in the angle of view during focus transitions, keeping your framing stable even when shooting video on a camera with no digital focus breathing correction.

With its 0.15m closest focusing distance (at 7 to 14mm, during AF) and 0.35x maximum magnification (at 14mm, during AF, centre of image), the RF7-14mm f/2.8-3.5L Fisheye STM lets you shoot very close to your subject and fill more of the frame with it. It’s also a great way to get unusual images by maximising the lens’ unique, wider-than-usual fisheye perspective!

Despite its larger aperture, the RF7-14mm f/2.8-3.5L Fisheye STM weighs just around 476g—12% lighter than the EF8-15mm f/4L Fisheye USM.  With its approximately 76.5mm diameter and 109mm barrel length, it is also smaller and lighter than the RF24-105mm f/4L IS USM standard zoom lens. It fits just as well on a drone or gimbal as it does in your hands!

Designed for easy operability, the RF7-14mm f/2.8-3.5L Fisheye STM has various dials, buttons, and switches for hands-on control. This includes the RF signature programmable knurled control ring, which offers an intuitive way to adjust an exposure setting of your choice, whether it’s the shutter speed, aperture, ISO speed, or exposure compensation.

It also has a lens function button, a feature previously available only on super telephoto lenses. While the button stops AF by default—useful for Servo AF control—it can be assigned to other functions such as depth of field preview.

Supports drop-in ND/CPL filters

Fisheye lenses have a protruding front element that makes them incompatible with screw-on front filters. The RF7-14mm f/2.8-3.5L Fisheye STM  is equipped with a rear drop-in filter mechanism that accommodates the Drop-in Variable ND Filter A/ Drop-in Circular Polarizing Filter A (both sold separately), which are also used with the Drop-in Filter Mount Adapter EF-EOS R. It is bundled with a Drop-in Clear Filter.

You can convert the photos or videos you shoot with the RF7-14mm f/2.8-3.5L Fisheye STM into immersive 2D 180° VR images or videos by using Canon’s EOS VR Utility software. The resulting images or videos can be viewed on either a head-mounted display or a computer. It’s a convenient way to create high-quality 2D VR content! 

As a professional-grade L-series lens, the RF7-14mm f/2.8-3.5L Fisheye STM is built to enable you to keep shooting high-quality images even under harsh conditions.
