The 105mm f/2.8 EX DG Macro sits in the middle of Sigma’s range of 1:1 true macro lenses. Keenly priced, it is designed for use with full frame digital SLR cameras, but can also be fitted to DSLRs with smaller APS-C size sensors. It covers a similar field of view to a 158mm lens in 35mm format when fitted to Nikon, Pentax and Sony cameras with 1.5x crop factors or 168mm with Canon DSLRs.
