Canon EF 14mm F2.8L II USM Lens Front and rear lens caps Lens hood (Built-In) Lens case The Canon EF 14mm f/2.8L II USM is an ultra-wide angle lens infused with an abundance of technology. Its large aperture allows fast, flash-free shooting in dim conditions and excellent depth of field control. The aperture?s circular design is also ideal for isolating subjects at large aperture by delivering smooth and even-looking background blur. In terms of image quality, the lens incorporates aspherical and UD elements, with the former guarding against spherical distortions and the latter minimising chromatic aberrations. It also has a Super Spectra Coating for accurate colour balance and high contrast and it suppresses ghosting and flare by absorbing unwanted reflections in the lens. This lens is also exceptionally quiet during shooting with its internal USM that ensures fast, accurate and silent operation with excellent holding torque, perfect for shooting situations such as a conference. In case you want to instantly regain control over focusing, the lens permits manual autofocus override.
