The lens supports both autofocus and manual focus, providing operational flexibility for different shooting styles and scenarios.
Available in Canon EF, Nikon F, Sony A, Pentax K, and Sigma SA mounts, it integrates with the vast majority of DSLR systems on the market. The 82mm filter thread accommodates a wide range of standard filters. Weighing 790g, it is a solid, substantial lens built to match the demands of full-frame optical performance.
