Sigma AF 28mm F1.8 EX DG Aspherical Macro Lens (Canon mount) w/Hood and Case

This large aperture wide-angle lens can be used for both digital and 35mm film SLR cameras. It has macro focusing capability with a fast F1.8 maximum aperture, which is ideal for Digital SLR cameras. With a minimum shooting distance of 7.8", reproduction ratio of 1:2.9 and a 75.4 degree angle of view, you can not only take pictures of the subject but also the surrounding scenery. Also, the iris diaphragm has 9 diaphragm blades to obtain beautiful out of focus images in the foreground and background.Sigma's advanced optical construction utilizes a floating focus system and two aspherical lens elements for superior peripheral brightness and compensation of aberrations and astigmatism. Super Multi Coating reduces flare and ghosting that tends to occur when using digital SLR cameras. The Dual-Focus (DF) mechanism eliminates the need for the front of the lens to rotate during auto-focus. The wide, textured, rubberized focus ring conveniently moves forward to click into AF position and back to select manual focusing. Also, this also allows the use of a Petal-type Hood and the easy use of a polarizing filter.Super Multi Coating to reduce flare and ghostingFast f/1.8 maximum apertureOptimized for both digital and 35mm film SLR camerasMacro capabilityDual-Focus mechanismAspherical lens elements to correct to correct for aberrations and astigmatismSigma 28mm F1.8 EX DG ASPHERICAL MACRO LensLens HoodLens Case4 Year Sigma USA Authorized Dealer WarrantyIn addition to the 1 year international warranty, when you register this EX lens with Sigma you will receive an extra 3 year extended warranty against defective materials or workmanship.
