Combining a huge field of view with distinct fisheye rendering, the Canon RF 7-14mm f/2.8-3.5 L Fisheye STM is an ultra-wide zoom for creating striking, dynamic photos and videos. The first fisheye lens for the RF series, this lens brings an immensely wide 190° angle of view, both circular and diagonal coverage depending on focal length and format, and a host of convenient new design details for working with the unique lens.

Relative to conventional focal length zooms, this fisheye zoom's change in focal lengths also affects the fisheye distortion and frame coverage.

At the 7mm position on a full-frame camera, this is a fully circular fisheye lens with a 190° angle of view. At the 14mm position on a full-frame camera, this is a diagonal, frame-filling fisheye with a 180° angle of view.

When used with APS-C-format cameras, there is a 'C' position on the zoom ring at approximately 8.7mm, which indicates the point at which vignetting will disappear and this lens will fully cover the sensor area. Between 7mm and 8.7mm, the fully circular image will not fit within the frame but there will be significant vignetting.

One of the most unique design details of this lens is the use of Canon's rear drop-in filter system, which debuted with their Drop-In Filter Mount Adapter EF-EOS R. A clear filter is included with the lens
