The Canon EF-mount Sigma 14-24mm f/2.8 DG HSM is an Art-series zoom, distinguished by its fast f/2.8 constant maximum aperture to suit working in available lighting conditions. Featuring a sophisticated optical design, this lens utilizes a series of low dispersion and aspherical elements to minimize both chromatic and spherical aberrations throughout the zoom range in order to achieve high sharpness, clarity, and color accuracy. A Super Multi-Layer Coating also helps to suppress lens flare and ghosting for color-accurate, contrast-rich imagery in a variety of lighting conditions. 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 thermally-stable composite. Additionally, a built-in lens hood helps to protect the front element as well as prevent stray light from causing flare. Wide-angle zoom is designed for full-frame Canon EF-mount cameras, however, is also suitable for APS-C models where it provides a 22.4-38.4mm equivalent focal length range. Three Special Low Dispersion (SLD) elements and three F Low Dispersion (FLD) elements markedly reduce chromatic aberrations and color fringing throughout the zoom range for improved clarity and color accuracy. 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. The rounded nine-blade diaphragm contributes to a smooth and pleasing bokeh quality. 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.
