The Sigma 70-200mm f2.8 APO EX DG Macro HSM II is an upgraded version of the 70-200mm f2.8 APO EX DG Macro HSM telephoto zoom lens. The Sigma HSM II features a large constant maximum aperture of f2.8 throughout the entire zoom range and a constant 100cm minimum focusing distance throughout the range means that this lens is great for close up work such as insects and small animals in particular, as these situations require a greater working distance to avoid disturbing your subject and thus ruining the shot.
APO Tele-Converter EX
