The Sigma 12-24mm f/4 DG HSM ART Lens for Canon is an EF-mount lens that refines Sigma's ultra-wide arena and delivers an image with little distortion.
The Sigma 12-24mm f/4 DG HSM ART Lens for Canon is Sigma's third-generation lens, that refines their ultra-wide arena and delivers an image with little distortion, and with a high resolution for crisp photos with a modern full-frame digital image sensor.
A member of Sigma's ART series, it boasts high image quality which is helped out by the use of FLD (F Low Dispersion) and Aspherical Elements, including an 80mm large-diameter molded glasses Aspherical lens, that minimizes aberrations and distortion. Furthermore, it uses a Super Multi-Layer Coating that minimizes flare and ghosting.
Benefitting handling, this Sigma 12-24mm f/4 DG HSM ART Lens for Canon is equipped with an HSM (Hyper Sonic Motor) with an optimized algorithm for speed and accuracy. The lens also offers a large focusing ring with full-time manual override settings for quickly making adjustments.
A Rounded 9-Blade Diaphragm improves image quality by helping create smooth bokeh, and the lens is constructed from a lightweight and durable TSC (Thermally Stable Composite).
Additionally, a built-in lens hood helps to protect the front element as well as prevent stray light from causing flare.
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 Lens/FX Format 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 SLD (Special Low Dispersion) element and five FLD (F Low Dispersion) 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 (Hyper Sonic Motor) also permits full-time manual focus control simply by rotating the focus ring at any time.
A Rounded 9-Blade Diaphragm contributes to a smooth and pleasing bokeh quality.
The front lens element has been treated with a water and oil-repellent coating to benefit from working in harsh environmental conditions.
Constructed using a TSC (Thermally Stable Composite) material for greater precision and use in broad temperature variations. 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.
