A long-range zoom creates a whole new way of looking at the world, and for many profoundly changes the way they see and record nature, wildlife and even photojournalistic assignments. Lightweight (1135 g/2.5 lb for L-Mount), specially sealed, and compact for its range (197.2 mm /7.8 inch for L-Mount), this newly crafted lens takes full advantage of SIGMA’s know-how in long-range telephoto optics applied to mirrorless camera technology (Sony E-mount and L-Mount). The 9-blade diaphragm enhances bokeh, and is especially exciting at longer focal length settings. The stepping motor in the lens is optimized for both phase detection and contrast AF, so eye-tracking technology is optimized. And there’s a 4 steps optical stabilization system that expands shooting opportunities in challenging lighting conditions.
