Overview
Canon has expanded its RF‑mount lineup with two ultra‑wide‑angle lenses: the 14mm f/1.4L VCM and the 7‑14mm fisheye. Both are aimed at professional photographers and videographers who need fast, distortion‑controlled optics for full‑frame bodies.
Design and Build Quality
Both lenses belong to Canon’s premium “L” series and feature robust, weather‑sealed construction. The front ring can be customized, as can the side control button, giving users quick access to aperture or focus settings. The 14mm lens weighs 476 g (16.8 oz) and the 7‑14mm fisheye is similarly lightweight, making them comfortable for handheld use.
Optical Formula
The 14mm f/1.4L VCM contains 18 elements in 13 groups, including Canon’s proprietary BR, UD and Fluorite elements. These glass types improve chromatic aberration control and overall sharpness. The 7‑14mm fisheye uses a complex arrangement to deliver a true 190° circular fisheye at 7 mm and a rectilinear ultra‑wide view at 14 mm.
Autofocus and Video Features
Both lenses employ a Voice Coil Motor (VCM) that provides fast, near‑silent autofocus—ideal for video work. The aperture ring offers a click‑stop mode for stills and a smooth, click‑free mode for seamless exposure changes during filming. Canon also claims focus breathing is suppressed, which helps maintain framing consistency when pulling focus.
Filter System
The 14mm lens includes a rear drop‑in filter slot, allowing the use of circular polarizers or variable ND filters without adding bulk to the front element. A clear filter ships standard, while additional filters are sold separately. This design is missing on the older EF 8‑15mm fisheye, which relies on front‑threaded filters.
Comparison with the Legacy EF 8‑15mm F/4 L Fisheye
Canon states the new fisheye is wider, faster (f/1.4 vs f/4) and optically superior. It is also lighter (476 g vs 540 g) and includes the rear filter slot. The close‑focus distance of 15 cm yields a 0.35× magnification, improving macro‑like capabilities.
Verdict
Canon’s new RF ultra‑wide‑angle lenses deliver professional‑grade build, impressive optics and video‑friendly features. The 14mm f/1.4L VCM is a versatile choice for stills and cinema, while the 7‑14mm fisheye offers creative flexibility with both circular fisheye and rectilinear perspectives. For users invested in the RF system, these lenses are compelling upgrades over older EF options.
