The EF 35mm f/1.4L II USM from Canon is an L-series prime wide-angle lens for full-frame and APS-C Canon DSLRs, featuring Blue Spectrum Refractive Optics and a maximum aperture of f/1.4, making it ideal for shooting in low-light situations and controlling out of focus areas. It has a minimum focusing distance of 28 cm with a 0.21x maximum magnification for working with close-up subjects. Two aspherical elements and one Ultra Low Dispersion (UD) element combine with the BR element to control chromatic aberrations and colour fringing, and a Subwavelength Coating has also been applied to reduce ghosting and lens flare. The Ultrasonic autofocus motor (USM) provides fast and near-silent AF operation. Full time manual focus override enables precise manual focus even when in AF mode. It is also dust and moisture-resistant.
