Used Canon EF 24mm F/1.4L Ultrasonic (USM) (77) 35mm SLR Auto Focus Wide Angle Lens

Professional wide-angle lens with an ultra-large maximum aperture of f/1.4. This is the first EF lens to employ both a replicated aspherical lens element to suppress distortion and spherical aberration, and a UD lens element to correct lateral chromatic aberration. Thanks to the floating construction, excellent corner-to-corner delineation is attained from 10 in. (25 cm) to infinity.
