Sigma's unique 24-35mm f/2 Art — the world's first full-frame f/2 zoom lens.
The Sigma 24-35mm f/2 DG HSM Art was released in 2015 as the world's first full-frame zoom lens with an f/2 maximum aperture. This unique specification essentially combines a 24mm f/2, 28mm f/2, and 35mm f/2 into a single lens, offering the speed of a fast prime with the convenience of a zoom. It was a groundbreaking achievement in lens design.
Optical performance is outstanding. Sharpness is excellent from f/2 throughout the limited zoom range — matching or exceeding many fast primes at these focal lengths. The Art line optical design delivers reference-class aberration correction. Bokeh is smooth and pleasant at f/2. The constant f/2 aperture provides consistent shallow depth of field across the range.
Nikon F mount in this listing — also available in Canon EF. Filter thread is 82mm. Weight is approximately 940 grams — heavy, reflecting the complex optical design needed for f/2 across a zoom range. Build quality is excellent with TSC construction and brass bayonet mount. HSM motor provides fast, quiet AF. No weather sealing.
Available on the used market at reasonable prices. Check AF accuracy and smooth zoom ring. The limited 24-35mm zoom range means you still need other lenses for telephoto, but within that range, this lens replaces three fast primes. A unique tool for event, documentary, and wedding photographers who value f/2 speed with zoom flexibility.
