Sigma 12-24mm f/4 DG HSM Art Lens (Canon EF)

The Sigma 12-24mm f/4 DG HSM Art Lens offers ultra-wide focal lengths with advanced design for reduced distortion and high sharpness. With low dispersion and aspherical elements, chromatic and spherical aberrations are minimized for improved clarity and color accuracy. A Super Multi-Layer Coating helps suppress lens flare and ghosting for optimal image quality in all lighting situations.

• EF-Mount Lens/Full-Frame Format
• Aperture Range: f/4 to f/22
• Five FLD Elements, One SLD Element
• Three Aspherical Elements
• Super Multi-Layer Coating
• Hyper Sonic Motor AF System
• Rounded 9-Blade Diaphragm
• Built-In Lens Hood

The Sigma 12-24mm f/4 DG HSM Art Lens boasts a Hyper Sonic AF motor with optimized algorithm for quick and accurate focusing. Its full-time manual override allows for easy adjustments. With a 9-blade diaphragm, smooth bokeh is ensured, while the lightweight, durable, and thermally-stable construction makes it a reliable choice for any photographer.

• As part of the Art line within Sigma's Global Vision series, this lens' is designed to achieve truly notable optical performance and is ideally suited for creative and artistic applications.
• Wide-angle zoom is designed for full-frame Canon EF-mount cameras, however is also suitable for APS-C models where it provides a 19.2-38.4mm equivalent focal length range.
• Constant f/4 maximum aperture provides consistent illumination throughout the zoom range.
• One Special Low Dispersion (SLD) element and five F Low Dispersion (FLD) elements markedly reduce chromatic aberrations and color fringing throughout the zoom range for improved clarity and color accuracy.
• Three aspherical elements control spherical aberrations and distortion for increased sharpness and accurate rendering.
• A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.
• Integrated HSM (Hyper Sonic Motor) realizes quick and quiet autofocus, which is further complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also permits full-time manual focus control simply by rotating the focus ring at any time.
• Rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality.
• Front lens element has been treated with a water- and oil-repellent coating to benefit working in harsh environmental conditions.
• Constructed using a Thermally Stable Composite (TSC) material for greater precision and use in wide temperature variations. Additionally, a brass bayonet affords improved mounting accuracy and rigidity. Additionally, rubber sealing is incorporated in the mount design to render it dust- and splash-resistant.
• This lens is compatible with the optional Sigma USB Dock for fine-tuning different lens characteristics and updating its firmware.
