Description — Sigma 24-70mm f/2.8 IF HSM
The Sigma 24-70mm F2.8 IF EX DG HSM is a standard zoom lens built for full-frame DSLR camera systems, spanning a 24mm to 70mm focal length range with a constant f/2.8 maximum aperture. The consistent f/2.8 aperture throughout the zoom range gives photographers reliable light-gathering capability whether shooting at the wide end or zoomed in to 70mm. It supports both autofocus and manual focus, giving shooters flexibility depending on the situation.
The lens is offered in Canon EF, Nikon F, Sony A, and Sigma SA mounts, covering the most common DSLR platforms. A 82mm filter thread accommodates a range of screw-in filters, though that larger diameter means filters will be a corresponding investment. At 790g, the lens has a solid, substantial feel.
One notable trade-off is the absence of image stabilization, so steady handheld shooting in dim conditions will depend on the fast f/2.8 aperture or body-based stabilization. For DSLR photographers seeking a versatile zoom covering wide-angle through short telephoto with a constant fast aperture, this Sigma lens covers the essential focal length range.
