A medium-length telephoto prime optimized for close-up shooting, the APO Macro 150mm f/2.8 EX DG OS HSM from Sigma is a unique lens, characterized by its bright f/2.8 maximum aperture, apochromatic designation, and close-focusing capability. The optical design employs three 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.
Making use of the strong optical assets, this macro lens is of course distinguished by its 1.25' minimum focusing distance and life-size 1:1 maximum magnification ratio, as well as a floating internal focus design that maintains consistent performance 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. Additionally, a removable, rotating tripod collar is included to better support working with the lens atop a tripod or monopod.
