High performance, fast aperture wide angle prime lens

The EF 24mm f/1.4L II USM has a large maximum aperture of f/1.4, offering the chance to capture superb low-light photographs, as well as a circular aperture and narrow depth of field to give pleasing background blur. A focal length of 24mm is ideal for wide-angle photography: making the lens well-suited to the needs of photojournalists, landscape photographers and those who enjoy taking images from a wider perspective.

Aspheric and UD elements

Image quality has been greatly improved with the EF 24mm f/1.4L II USM thanks to the addition of two high-precision aspheric lenses to correct aberration including curvature of field and distortion. Chromatic aberration common in wide-angle shooting is also combated by the inclusion of two UD lenses, ensuring optimum image quality and corner-to-corner detail.

Subwavelength structure lens coating

Designed for use in digital photography, Canon's patented lens element coating helps minimise the ghosting and flare caused by internal reflections. By eliminating the cause, the coating reduces reflections and helps to deliver crisp, clear images.

USM focus motor

The EF 24mm f/1.4L II USM's near-silent Ultra Sonic Motor (USM) provides super-fast auto-focusing with full-time manual override. The floating internal focus system also helps maintain high image quality throughout the focal range.

Robust build quality

Canon lenses are built to withstand regular use in the most testing environments. Weather and dust seals provide added protection, and a lens hood and pouch are also included in the package.

Lead-free optics

Environmentally friendly lead-free glass is used throughout the construction of the EF 24mm f/1.4L II USM.
