Lens Overview — Sigma 12-24mm f/4.5-5.6 II
Key Features — Sigma 12-24mm f/4.5-5.6 II
12-24mm Ultra-Wide Zoom: The 12mm wide end delivers an extremely broad field of view on full-frame bodies, well suited to landscapes, interiors, and architectural photography.
Full-Frame Coverage: Designed specifically for full-frame DSLR sensors, ensuring edge-to-edge image quality without vignetting or crop factor concerns on compatible bodies.
F4.5-5.6 Variable Aperture: The maximum aperture opens to f/4.5 at 12mm and f/5.6 at 24mm, providing a reasonable light-gathering range across the zoom.
HSM Autofocus Motor: Sigma's Hypersonic Motor delivers fast, quiet autofocus operation and also allows full-time manual focus override without switching modes.
Three-Mount Compatibility: Available in Canon EF, Nikon F, and Sony A mounts, making it a practical ultra-wide option across several major DSLR platforms.
No Filter Thread: The protruding front element design that enables 12mm coverage on full-frame makes a conventional filter thread impossible, so standard screw-on filters cannot be used.
