Sigma 14-24mm F2.8 DG HSM Art Lens for Nikon F

Designed to team up with 50-megapixel-plus cameras, the Sigma 14-24mm F2.8 DG HSM Art Lens for Nikon F offers outstanding F2.8 brightness throughout the zoom range and delivers top-level image quality at every focal length and every shooting distance while minimizing distortion. It is the definitive large-diameter ultra-wide-angle zoom lens for these reasons.

Furthermore, this lens s an Art-series zoom, distinguished by its fast f/2.8 constant maximum aperture to suit working in available lighting conditions. It 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 with a sophisticated optical design.

• Exclusive low-dispersion glass - Most chromatic aberration can be removed by combining a high-refractivity convex lens element with a low-refractivity concave element. Yet residual chromatic aberration known as “secondary spectrum” may still remain. To minimize this secondary spectrum, which can be a serious issue with conventional lenses, SIGMA lenses feature up to three types of exclusive low-dispersion glass offering superior performance: ELD (Extraordinary Low Dispersion), SLD (Special Low Dispersion) and FLD (“F” Low Dispersion). In particular, FLD glass offers ultra-low dispersion in combination with high transmittance and the anomalous dispersion characteristics of fluorite.
• Fast AF with full-time manual focus - Its function allows the lens to be switched to manual focus simply by rotating the focus ring.
• Designed to minimize flare and ghosting - From an early stage in the lens design process, flare and ghosting have been measured to establish an optical design resistant to strong incident light sources such as backlighting. SIGMA’s Super Multi-Layer Coating reduces flare and ghosting to help photographers produce sharp and high-contrast images even in backlit conditions.
• High-precision, rugged brass bayonet mount - The brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.
• Rounded diaphragm - The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
