Canon EF 24mm f/1.4L USM Wide Angle Lens for Canon SLR Cameras

Canon EF Autofocus Lenses Canon s reputation for excellence in optics has been well established for years. And with the introduction of EF lenses for the EOS, it s only getting better. EF Lenses have the largest diameter mount of any 35mm camera, which not only strengthens the whole system, but permits optical innovations never before possible. L-Series lenses have better sharpness and contrast because Canon uses aspherical elements to eliminate spherical aberrations. In addition, the L-Series telephotos use UD (Ultra-low Dispersion) glass to reduce chromatic aberration resulting in more accurate colors. A built-in Ultrasonic focusing Motor (indicated by USM) provides pro-quality AF speed with split-second accuracy. What makes this wide angle lens so unique is that it s the first EF lens to employ both a replicated aspherical element and a UD element to correct distortion and spherical aberrations and eliminate chromatic aberrations often experienced with wide angle lenses. It also incorporates a floating construction for remarkably high resolution and distortion-free images at all distances within the entire focusing range (9.84 to infinity, even at maximum 1.4 aperture). Its rear focusing design maintains a constant lens length and the front doesn t rotate, making it easier to use special effects filters and the bayonet mount lens hood. This lens accepts 77mm filters.
