Canon designed this pro-quality lens for premium performance with their EOS SLR cameras. It produces vibrant wide-angle images when you pair it with a full-frame camera like the EOS 5D. An extremely large maximum aperture makes it ideal for shooting in lower-light environments. Use this lens on your camera to take group photos at dusk without using a flash, or snap pictures of a vast skyline from the top of a building.

Superior optics ensure you'll get crystal-clear, high-contrast images. Your photos will be clear and detailed across the entire field of view — from one edge to the other — thanks to two aspherical elements. Two UD lens elements help to minimize chromatic aberration, and a special lens coating virtually eliminates ghosting and flaring caused by off-axis sun rays. A powerful ultrasonic motor (USM) provides silent, precise auto focusing.

Canon 24mm L II prime!!

Written by: Flexfoto from Guam on August 23, 2015

Crutchfield Customer Review (What's this?)

This glass is a super sharp low light wide angle beauty of a lens. IMHO 24mm in full frame is the perfect wide angle focal length, being not too wide but still manages to get the composition you'd desire, without too much distortion. Even on an APS.C sensor the lens remains relatively wide with a 38mm focal equivalent.

Pros: Sharp!!

Product Research


Overview: The Canon EF24mm f/1.4L II USM lens is an L-series, fixed length wide angle lens for Canon EOS cameras. The lens has two high-precision, large-diameter aspherical and UD lens elements, which result in outstanding image delineation. The lens includes the LP1319 Lens Case and the EW-83K Lens Hood.

Sub Wavelength Coating (SWC): The lens elements have a newly-designed anti-reflective SWC (Sub Wavelength Coating) that minimizes ghosting and flaring across the lens surface, regardless of the angle with which light enters or exits.

Ultrasonic Motor (USM): The EF24mm lens is equipped with an Ultrasonic Motor (USM) for silent, high-speed auto focusing.

Focusing Ring: Regardless of whether you're in manual or auto focus mode, the focusing ring always works. This means you can auto focus on a subject, but manually change the focus by turning the focusing ring.

Focus Mode Switch: You can switch between Auto Focus and Manual Focus using the two-way AF/MF switch on the barrel of the lens.

Lens Hood: The lens kit includes the EW-83K lens hood to keep unwanted light out of the lens, and protects the front of the lens. The hood can be reverse-mounted on the lens for storage. When installed, the hood adds approximately 2-3/16" to the overall length and 15/16" to the overall diameter of the lens.

Optional Filters: The EF24mm lens has a 77mm mounting thread on the front of lens for attaching screw-on type filters.
