The Sigma 28mm f/1.8 EX DG Lens Sony Fit has a macro focusing capability with a fast maximum aperture, ideal for digital SLR cameras. This lens has an advanced optical construction in order to obtain adequate periphal brightness with open aperture. It incorporates a floating focus system and uses two aspherical lens elements for minimising distortion, aberration and astigmatism. Another bonus feature is the use of a petal-type hood and the easy use of a polarising filter. The iris diaphragm blades obtain beautiful out of focus images in the foreground and background.
