Sigma 105mm f/2.8 EX DG OS HSM Macro Lens for Canon EF with 7-Piece (Black)
Sigma 105mm f/2.8 EX DG OS HSM Macro Lens for Canon EF with 7-Piece (Black). A classic for close-ups, the Canon EF-mount 105mm f/2.8 EX DG OS HSM Macro from Sigma is a short-telephoto prime characterized by its ability to achieve a 1:1, life-size magnification along with a 1′ minimum focusing distance for macro applications. The optical design employs two SLD elements to virtually eliminate chromatic aberrations and color fringing throughout the focusing range for improved clarity and color rendering. A Super Multi-Layer Coating has also been applied for greater contrast when working in strong lighting conditions.
