NEW YORK, NY--(Marketwired - February 05, 2015) - Ultra-wide-angle lenses have seen a renaissance of sorts, with numerous manufacturers updating and adding to their line. Just last year, Canon released a new 16-35mm lens, and is now introducing the even-wider EF 11-24mm f/4L USM Lens. The full-frame L-series lens has an impressive starting focal length of 11mm, which will allow users to capture a seriously wide field of view. Also, the constant f/4 aperture guarantees consistent performance and light transmission throughout the zoom range.
With such a dramatic angle of view, this lens will be very desirable for landscape and architectural photographers, and as such, it is designed to withstand the elements with a high resistance to dust and water. Also, the front and rear lens surfaces have a fluorine coating, which reduces the amount of smearing and fingerprints that can affect image quality.

The optical design is, of course, the key component of any lens, and this one delivers with a variety of the latest and greatest technologies. It incorporates both a Super UD and a UD element to reduce chromatic aberrations, along with four aspheric elements to minimize distortion throughout the zoom range, something incredibly difficult and important at these focal lengths. Additionally, the Canon EF11-24mm f/4L USM L series lens features both a SubWavelength Coating (SWC) and an Air Sphere Coating (ASC) that will greatly reduce flare and ghosting.
For general handling and operation, the lens has an internal focusing system with a ring ultrasonic motor (USM) as well as a high-speed CPU and optimized AF algorithms which provide fast, accurate, and quiet autofocusing. Manual focus is available at all times through the physical focusing ring, and it has a minimum focusing distance of 11", allowing photographers to work in cramped spaces without issue. Its circular nine-blade aperture diaphragm helps to create soft, pleasing out-of-focus highlights.
You can now pre-order the Canon EF 11-24mm f/4L USM L series lens for $2,999

Of note is the physical design of the lens, which has a bulbous front element and a built-in lens hood. This hood reduces the chance of flaring from external light sources and offers a degree of protection against accidental impact. Bundled with the lens are a dedicated front lens cap and a storage case.
