As a result this lens is an excellent choice for advancing amateurs and semi-professional photographers with a full frame or APS-C DSLR. The Sigma 70-200mm f/2.8 EX DG Macro HSM II zoom lens boasts a robust EX build, making it capable of surviving prolonged use outdoors, with the Hyper Sonic focus motor being quick and quiet.
