Wide-Angle Prime for Full-Frame
This Canon EF 35mm f/1.4L II USM is an L-series wide-angle prime lens built for full-frame cameras. Its fast f/1.4 maximum aperture suits wedding, portrait and interior photographers who need shallow depth of field and strong low-light performance. The blue spectrum refractive optics element helps control chromatic aberration across the frame.
Upgrade from Slower or Older 35mm Glass
Photographers moving from an f/2 or variable-aperture zoom gain two extra stops of light gathering and the L-series build quality with weather sealing. The jump is worth it when subject isolation and corner-to-corner sharpness at wide apertures become daily requirements rather than occasional wishes.
EF Mount with 72mm Filter Thread
The lens mounts directly to any Canon EF-compatible body and accepts 72mm filters without an adapter. Its 14-element, 11-group construction keeps the barrel at 3.20 by 4.20 inches and approximately 26.80 ounces, leaving room in a standard kit bag for a second prime or flash unit.

| Features | L-series wide-angle single focus lens introduces Canon's newly-developed optical element, BR Optics*, which helps produce impressively high quality images by helping to maximize performance and reduce chromatic aberration. Two aspheric lenses and one UD lens help provide a high level of image quality. Improved durability for use in harsh environments helps ensure reliability and dependability. Subwavelength Coating (SWC) helps significantly reduce lens ghosting and flare. Shortest minimum focusing distance in its class (0.28m) and increased maximum magnification (0.21x) help expand t |

Questions about this item
What filter-thread size does the 72 mm front accept?
The front barrel takes 72 mm screw-in filters, matching the 2.80 inch diameter listed in the specifications.
How do I mount the EF 35 mm f/1.4L II USM on a Canon EOS body and what step is often missed?
Align the red EF mount index on the lens with the red dot on the camera, twist clockwise until it clicks, then set the focus-mode switch to AF so the ultrasonic motor drives autofocus.
Which seals should I check periodically to maintain the weather-sealed design?
Inspect the rear-mount gasket and the fluorine-coated front element for damage or debris; clean the front coating only with a blower and microfibre cloth to preserve the water-repellent layer.
