The latest in the highly successful "The Expanded Guide" series, this title explores the huge range of Sigma lenses. Andy Stansfield is an internationally recognised author. Written by an expert and with worked examples, this guide is jargon free, full-colour, inclusive and easy to use with its extensive tabbing system. This title explores the huge range of Sigma lenses for digital SLR cameras and explains how precision engineering helps photographers to maximise their creativity by fulfilling the full potential of the equipment. Information is given on lenses from the standard, macro and wide angle types, to special lenses from aspherical ASP models that give high optical performance in a compact size, APO types that minimize colour aberration, to the OS range that compensates for camera shake.
