Sigma 28mm f/1.4 DG HSM Art - 28MM-F1.4

The 28mm f/1.4 DG HSM Art Lens from Sigma incorporates two FLD (“F” Low Dispersion) glass elements and three SLD (Special Low Dispersion) glass elements. In addition, the 28mm F1.4 effectively arranges three aspherical lenses, including a large-diameter aspherical lens to provide thorough correction of magnification chromatic aberration — encountered particularly in wide-angle lenses. This offers high resolution over the entire sensor, while sagittal coma flare is thoroughly corrected and distortion is also minimized to the fullest.Featuring water- and oil-repellent coating on the front lens element and its overall dust- and splash-proof structure ensures excellent performance from this 28mm even in the most challenging shooting conditions. The high-speed AF, thanks to the HSM (Hyper Sonic Motor) with an updated algorithm, captures your desired moment instantly. Available in Sigma, Nikon, Canon and Sony E camera mounts, this lens is a great contender for street photography, as well as shooting landscapes and night skies.ApplicationsTypical Photography:CreativeTravelLandscapeWedding & EventsFamilyFeaturesBest-in-class performanceDust- and splash-proof structureDesigned to minimize flare and ghostingDesigned to meet all shooting conditionsCompatible with Canon Lens Aberration CorrectionNikon electromagnetic diaphragm mechanism includedManual Override (MO) capable of switching two full-time manual modesSpecificationsCategory: Lenses, Wide Angle LensesClass: ArtLens Construction: 17 elements in 12 groupsAngle of View (35mm): 75.4°Number of Diaphragm Blades: 9 (Rounded diaphragm)Minimum Aperture: F16Minimum Focusing Distance: 11 in / 28cmFilter Size (mm): φ77mmMaximum Magnifications: 1?5.4Dimensions:(Diameter x Length): 3.3 in. x 4.2in.
