Rent NowThe Canon EF 14mm f/2.8L II USM is an ultra-wide-angle prime lens designed for Canon EF-mount cameras, taking in a massive 114-degree diagonal field of view. As part of Canon’s flagship L-series lineup, it’s aimed at landscape, architecture, interior, and astrophotography photographers who need genuinely wide, corrected coverage from a single fixed focal length.
Optically, the lens offers a 14mm focal length with a maximum aperture of f/2.8, well suited to working in difficult lighting conditions and making it a popular choice for astrophotography as well as demanding architectural and interior work. The optical design incorporates two aspherical elements and two ultra-low dispersion (UD) glass elements, a notable improvement over the original EF 14mm f/2.8L USM’s single aspherical element, controlling both spherical and chromatic aberrations to deliver a high degree of sharpness, clarity, and color accuracy across the frame. Canon’s Super Spectra coating further suppresses flare and ghosting for increased contrast and color fidelity in backlit or harsh lighting conditions, and the lens’s rectilinear design corrects for distortion, giving it strong separation between foreground and background elements typical of ultra-wide optics. A rounded 6-blade diaphragm rounds out the optical package.
Autofocus is handled by a ring-type Ultrasonic Motor (USM) paired with an internal focusing system, delivering fast, precise, and quiet autofocus performance along with full-time (mechanical) manual focus override. As an L-series lens, the EF 14mm f/2.8L II USM features dust- and moisture-sealed construction, reflecting Canon’s professional-grade build standards, and includes a built-in, petal-shaped lens hood that protects the front element, improves contrast, and helps prevent vignetting.
Build quality is compact for an ultra-wide L-series prime, measuring approximately 80 x 94mm and weighing about 645g. Due to its bulbous front element and built-in hood, the lens does not accept front filters and is not compatible with Canon’s EF12 II or EF25 II extension tubes.
As a full-frame-compatible lens, the EF 14mm f/2.8L II USM delivers its full 114-degree ultra-wide field of view on full-frame Canon bodies, an effective 18mm equivalent on Canon’s 1D-series (1.3x crop) bodies, and an effective 22.4mm equivalent field of view on APS-C (1.6x crop) bodies.
