Ultra-wide Sigma Art zoom reaching 12mm on full frame, one of the widest rectilinear zooms available for architecture and landscapes.
The Sigma 12-24mm f/4 DG HSM Art is an ultra-wide-angle zoom for full-frame cameras that reaches an extraordinary 12mm at the wide end, providing one of the widest rectilinear perspectives available from any zoom lens. The constant f/4 aperture maintains consistent exposure across the entire zoom range.
The 12mm ultra-wide perspective creates a dramatic field of view that encompasses nearly 122 degrees, making this lens exceptional for architectural interiors, real estate photography, and landscape work where maximum coverage is essential. The rectilinear design keeps straight lines straight, unlike fisheye alternatives at similar focal lengths.
Build quality is excellent as part of Sigma's Art line, with a robust metal barrel, quality sealing, and the precision engineering that has earned the Art series a strong reputation. The Hyper Sonic Motor provides fast, accurate autofocus, and the lens accepts rear-mounted gel filters since the bulbous front element prevents front filter use.
The Sigma 12-24mm f/4 DG HSM Art offers a wider perspective than virtually any competitor at an attractive price point. On the used market it provides outstanding value for architectural, real estate, and landscape photographers who need the widest possible rectilinear coverage from a single zoom lens.
