Overview 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. Balancing the optical assets, this lens also features a floating internal focus design that maintains consistent sharpness throughout the focusing range. A Hyper Sonic Motor affords quick and quiet autofocus performance while an Optical Stabilizer minimizes the appearance of camera shake for sharper handheld shooting.
