Sigma F4 DG AF HSM Art - Lens for reflex camera (12-24 mm), black CANON
The third generation 12-24mm f / 4 DG HSM Art Lens from Sigma, available here with a Canon EF mount, refines its ultra-wide sand and offers a low distortion, high resolution image for sharp photos with a modern full digital image sensor frame
The Sigma Art series features high image quality that is aided by the use of FLD and aspherical elements, including an 80mm diameter aspherical lens that minimizes aberrations and distortions. In addition, it uses a Super Multi-Layer coating that minimizes flare and ghost images.
-
As part of the Art line of Sigma's Global Vision series, this lens is designed for truly remarkable optical performance and is ideal for creative and artistic applications.
-
This 12-24mm f/4 wide-angle lens is designed for Canon EF-mount full frame format cameras and can also be used with APS-C models where it will provide an equivalent focal length of 19.2-38.4mm.
-
Maximum aperture f / 4 constant provides consistent performance across the entire zoom range.
-
F Dispersion and aspheric elements have been incorporated, including an 80mm large diameter moulded glass aspheric element, to correct chromatic aberrations throughout the focusing range and help ensure high image sharpness, clarity and contrast regardless of focus Point or aperture adjustment. This optical design also helps control distortion and limit vignetting.
-
A Super Multi-Layer coating has been applied to the lens elements to minimize lens flare and ghost images and help produce high-contrast, neutral color images, even in backlit conditions.
-
The integrated HSM (Hyper Sonic Motor) performs fast, quiet autofocus, complemented by an optimized AF algorithm to produce smoother focusing performance. The HSM also allows full-time manual focus control by simply turning the focus ring at any time.
-
Minimum focusing distance of 9.4" when shooting at 24mm to get close to your subjects.
-
A rounded nine-knife diaphragm helps produce an attractive out-of-focus quality.
-
The lens is constructed using a thermally stable composite material (TSC), along with traditional metals, for greater accuracy and use in wide temperature variations.
-
The bayonet mount is constructed of brass for assured accuracy and durability.
-
Dust and splash resistant construction with rubber sealing to protect the substrate and a water-repellent and oil-repellent coating on the front and rear elements.
-
This lens is compatible with the optional Sigma USB Dock to adjust lens features and update your firmware.
