Description — Sigma 18-35mm f/1.8 DC HSM
The Sigma 18-35mm f/1.8 DC HSM Art Lens is a zoom lens built specifically for APS-C format DSLR cameras, spanning a standard focal length range of 18mm to 35mm. Its headline specification is a constant maximum aperture of f/1.8 across the entire zoom range — a genuinely rare feature that allows for consistent exposure and creative control regardless of where you are in the zoom. The lens supports both autofocus and manual focus, giving shooters flexibility in how they work.
It is available across five DSLR mount options — Canon EF, Nikon F, Sony A, Pentax K, and Sigma SA — making it one of the more broadly compatible lenses in its category. The 72mm filter thread accommodates a wide selection of standard filters, and the lens weighs in at 810g. One practical consideration: this lens has no image stabilization, so handheld shooting in challenging light will require attention to shutter speed and technique.
