Description

The Canon EF 14mm f/2.8L USM is a professional-grade, ultra-wide-angle prime lens in Canon’s prestigious L-series lineup. Offering an expansive 114° diagonal field of view on full-frame cameras, it allows photographers to capture dramatic perspectives, making it ideal for architecture, interior photography, landscapes, and astrophotography.

Its bright f/2.8 maximum aperture provides versatility in low-light situations and the ability to shoot handheld in dim environments. The lens design incorporates aspherical elements to control distortion and enhance sharpness across the frame.

The ring-type Ultrasonic Motor (USM) ensures fast, precise, and nearly silent autofocus, with full-time manual focus override for fine adjustments. The lens features a rugged metal body with weather-resistant L-series construction, and an integrated petal-shaped hood to help reduce flare.

Due to its large, bulbous front element, the lens cannot accept conventional screw-in front filters; instead, it provides a rear gelatin filter holder for creative or protective filtering.

While this original version is known for its solid build and distinctive rendering, it was later succeeded by the EF 14mm f/2.8L II USM, which offered improvements in sharpness, coatings, and weather sealing.
