Description — Sigma 12-24mm f/4 DG HSM
The Sigma 12-24mm f/4 DG HSM Art Lens is an ultra-wide-angle zoom designed for full-frame DSLR systems, offering a focal length range of 12mm to 24mm at a constant maximum aperture of f/4. Available in Canon EF, Nikon F, and Sigma SA mounts, this lens provides flexibility for photographers across major DSLR platforms. It supports both autofocus and manual focus, allowing shooters to adapt to different creative or technical requirements on the fly.
Weighing in at 1,151 grams, the lens reflects its robust full-frame design. One practical note: there is no filter thread, so traditional screw-on filtration is not an option without specialty solutions — a trade-off common to extreme ultra-wide designs. Image stabilization is not included, making it especially important to consider shutter speed when working in challenging lighting. For landscape, architecture, and interior photographers who need to push to genuinely extreme wide angles on a full-frame DSLR, the 12mm minimum focal length of this Art series zoom makes it a distinctive option in its class.
