For filmmakers seeking high precision focus in a shallow wide shot, the Canon EF 24mm f/1.4 II Prime Lens is an incredibly fast glass with robust physical construction and sophisticated optical design. The lens allows for sharpness across the sensor, even on the edges of full-frame sensors, because of two high-precision, large-diameter aspherical lenses. Have no worries about ghosting and flaring - these lens elements utilize an anti-reflective SWC (Sub Wavelength Coating). Add in a circular aperture and the legendary dust- and water-resistant L-series construction, this lens will serve you well on your next shoot!
