Canon EF 14mm f/2.8L USM Wide Angle Lens

From the Manufacturer This ultra-wide-angle lens has the shortest focal length in the L-series. Element 2 is an Aspherical lens to correct distortion. Other aberrations such as astigmatism are also corrected, resulting in ideal image quality. The lens has a fixed, petal-type hood and a gelatin filter holder at the rear. This is a true rectilinear ultra-wide-angle lens that’s absolutely corrected for linear distortion--straight lines remain straight. It’s outstanding for shooting in confined areas and interiors, and is often used by professionals because of the unique "look" its extreme wide angle perspective provides. The optics are superb, highlighted by a ground and polished aspherical element. It has a gel filter holder in the rear that allows up to three gel filters to be used for color correction. Wide and Fast If you need an ultra-wide angle and a large aperture, one of the following lenses will fit the bill. Ultra-wide-angle lenses can capture scenes beyond your natural field of vision. The EF 15mm f/2.8 Fisheye, the widest of them all, has a 180° angle of view. For more normal-looking wide-angle shots, there are longer wide-angle lenses up to 35mm with the maximum aperture you need.
