EF11-24mm f/4L USM: expanding your
creative horizons

The EF11-24mm f/4L USM is Canon’s widest ever full-frame ultra-wide zoom lens, designed to give photographers new wide-angle possibilities with the ultimate in sharpness. Four aspherical glass elements reduce distortion throughout the zoom range, achieving superb image quality right across the frame. Ultra-low Dispersion (UD) and Super UD lens elements guard against coloured fringing along high-contrast edges.

Who is it for?

The EF11-24mm f/4L USM is an advanced ultra wide-angle zoom that brings new creative possibilities to photographers shooting landscapes, travel, architecture and interiors, as well as filmmakers seeking a high performance wide-angle lens where image quality is paramount.

Key features

  • World’s widest angle ultra-wide zoom with 11-24mm focal length.*
  • f/4 fixed aperture, high-performance standard zoom L-series lens.
  • Uses four aspherical lens elements (including the world’s largest diameter ground aspherical lens within a photographic lens) and UD and Super UD lens elements, ensuring the highest image quality.
  • Canon unique SWC and new ASC anti-reflective coatings.
  • Fluorine coating on the lens surfaces to prevent dirt sticking to lens elements.
  • Silent, fast autofocus using a ring type USM.
  • A nine-blade circular aperture creates beautiful out-of-focus highlights.
  • Full-time manual focusing.
  • Minimum focusing distance 0.28m (at 24mm zoom position).
  • Highly resistant to dust and water allowing shooting in the harshest conditions.

* Excluding fisheye lenses.


The EF11-24mm f/4L USM features multiple lens coatings, which minimise the internal reflections that can cause flare and degrade image quality. Canon’s unique Subwavelength Structure Coating (SWC) is applied to two of the lens’ elements, while a new technology – Air Sphere Coating (ASC) – is used on a third element.

The new Air Sphere Coating has been developed by Canon to minimise reflections and flare. This is a hybrid coating consisting of nano particles that trap capsule-like air between the ASC layer and conventional multi-layer coatings. The Air Sphere particles form a super low reflective coat on the surface of the lens element to reduce reflection and act as a ‘crash mat’ to slow light down to roughly the same speed as light travels through glass, thus preventing the cause of reflection.

Both the SWC and ASC coatings work by slowing down light gradually as it passes from air to glass. Abrupt changes in speed can lead to reflections, which spoil image quality. By slowing down light gradually before it passes through the lens, such negative effects are minimised.


The EF11-24mm f/4L USM uses a completely new patented lens design. The optical design features 16 lens elements in 11 groups with a three group zoom and rear focus. The lens’ use of four aspherical lenses (including the world’s largest diameter ground aspherical lens within a photographic lens and three glass-molded lenses) helps to control distortion, keeping it at a very low rate throughout the entire zoom range. The inclusion of both a UD lens and a Super UD lens minimises chromatic aberration that tends to occur mainly around the edges at the wide-angle setting, as well as eliminating colour blurring around the edges of the subject. This ensures high-quality images with high levels of resolution and contrast.


The EF11-24mm f/4L USM uses a combination of a ring type USM to achieve high-speed AF. For EOS-1D X, EOS 5D Mark III, EOS 5DS and EOS 5DS R users the lens belongs to group I for AF point configuration.


Due to the weight of the front optical group a new mechanical design was required, to support the weight but still ensure a smooth focus and zoom mechanism. The EF11-24mm f/4L USM features the same level of waterproof and dustproof construction as the EF24-70mm f/2.8L II USM and EF70-200mm f/2.8L IS II USM lenses. The mount, the switch panel, zoom ring and focusing ring are all designed to prevent dust and moisture from getting into the lens, making it suitable for taking pictures even in harsh conditions.

The focal length is wider than any full-frame lens released so far with the exception of fisheye lenses, which tend to distort images. The EF11-24mm f/4L USM offers the widest angle of any current fixed focal non-fisheye lens, whilst offering the flexibility of a zoom. Producing a lens design that offers such a wide angle with little distortion and constant aperture is a feat of design and engineering made possible through Canon’s excellence in optics.


Fluorine coatings are applied to front and rear elements allowing the lens’ optics to be kept cleaner by the non-stick properties of the coating, which prevent dust and water drops adhering to the lens elements and make cleaning easier.


As the front lens element is very large and has a high level of curvature, filters cannot be fitted to the front of the lens but instead a slip-in filter holder for cut gelatin filters is provided at the rear of the lens.
