• Flare-Free Imaging: The Super Multi-Layer Coating reduces lens flare and ghosting, enhancing contrast and color rendition for pristine, professional-quality photos.

• Swift and Silent Autofocus: The Hyper Sonic Motor ensures fast, quiet, and accurate autofocus, providing seamless shooting experiences in various scenarios.

• Durable & Lightweight Construction: Crafted with Thermally Stable Composite (TSC), the lens offers robust durability while remaining lightweight and resistant to temperature fluctuations.

• Fine-Tune with Sigma USB Dock: Take control of your settings using the Sigma USB Dock, ensuring optimal autofocus and customization tailored to your unique photographic needs.

• Minimized chromatic aberrations - Three FLD (“F” Low Dispersion) glass elements and four SLD (Super Low Dispersion) glass elements help minimize transverse chromatic aberration, which tends to be noticeable in shots taken with ultra-wide-angle lenses. Offering excellent peripheral brightness, this lens delivers outstanding image quality from the center to the edges.
• Minimized distortion - Serving as the front lens element, the large φ80mm precision-molded glass aspherical lens effectively minimizes distortion. Offering excellent peripheral brightness, this lens delivers outstanding image quality from the center to the edges.
• Distinctive bokeh effect - Even at the 14mm ultra-wide angle of view, F1.8 brightness makes possible a very shallow depth of field with the subject standing out dramatically against a bokeh background. It’s the unique mode of expression that only a large-diameter lens can deliver.
• 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.
• Designed to minimize flare and ghosting - SIGMA’s Super Multi-Layer Coating helps further reduce flare and ghosting and provides sharp, high-contrast images even in backlit conditions.
• Hypersonic Motor (HSM) - Delivers ample torque to the focusing group for outstanding speed, ensuring exceptionally stable performance even at lower speeds. Along with the optimized AF algorithm, this feature delivers fast autofocus photography.
• Fast AF with a full-time manual focus - Full-time manual focus function allows the lens to be switched to manual focus simply by rotating the focus ring. *Note: The operation of full-time MF may vary based on mount type.
• Mount with Dust and Splash Resistant Structure - Since the area of the lens most vulnerable to dust and other foreign bodies is the mount, rubber sealing* helps provide peace of mind. In addition, the front lens element features a water- and oil-repellant coating that helps the lens perform well in the rain, near water, and in other challenging conditions. *Except for SIGMA mount.
• Rounded diaphragm - The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
• 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.
