Canon EF 11-24mm f/4L USM Wide Angle Lens

The Technical Details Behind This Lens

The Canon EF 11-24mm f/4L USM Wide Angle is a versatile lens that utilises advanced optics to produce high-quality images. It’s L-series design is created for full-frame EOS DSLRs, however it can also be mounted on APS-C sized Canon mirrorless cameras. Chromatic aberrations are significantly minimised by the application of a super UD and a UD element. Plus four aspherical elements have been used to reduce distortions across the zoom range.

A linear autofocus motor has been implemented to ensure that the focusing is precise, quiet and quick. Further support is provided through the Power Optical Image Stabiliser, which includes a Dual IS function for specific Canon cameras. Moreover, the lens features a weatherproof design that keeps away dust and moisture, thereby letting you use it under rough conditions.

Top Three Reasons We Think You Will Love The Canon EF 11-24mm f/4L USM Wide Angle Lens

• Includes protective coatings that prevent distortions and aberrations while reducing smudges and marks.
• An internal focusing system with an ultrasonic motor ensures superior focus.
• Sharp contrast and accurate colours are achievable across the whole zoom range.

Sharp and True Imaging

The lens’s composition includes 16 Elements in 11 Groups. An ultra-low dispersion and one super ultra-low dispersion element have been implemented to combat chromatic aberrations. Four aspherical elements have been added to reduce distortions. Two kinds of coating have been provided with the lens - an Air Sphere Coating (ASC) and a Subwavelength Coating (SWC). This means you will experience less flaring and ghosting and will achieve excellent contrast and clarity. The lens also incorporates rear insert-type gelatin filters.

A dust and water-resistant design make the lens appropriate for outdoor usage and in inclement weather conditions. The front and rear elements of the lens have fluorine coatings applied to them, which prevents them from attracting fingerprints and smudges. The coatings also make the process of cleaning your lenses much easier.

Fast Autofocus

This 11-24mm wide-angle zoom lens is compatible with full-frame Canon EF-mount DSLRs. It can also be used with APS-C camera models for which you will get an equivalent focal length range of 17.6 to 38.4mm. A constant maximum aperture of f/4 is available across the whole focal length of the lens, resulting in consistent light transmission across the zoom range. A maximum aperture of f/22 lets you shoot pictures with high clarity under good lighting conditions. The minimum focusing distance on this lens is 11.02" (28 cm).

The focusing system on this lens delivers exceptional performance. It utilises a ring-type Ultrasonic motor to deliver an autofocus mechanism that is smooth and fast. An internal focusing design helps you perform manual focus operations efficiently. The focusing system produces minimum noise while operating.
