Overview:

The Sigma 105mm F1.4 DG HSM Art Lens stands out as a remarkable choice for photographers seeking a high-performance short-telephoto prime lens. Renowned for its exceptional brightness, the lens's f/1.4 aperture not only excels in low-light conditions but also provides a stunningly shallow depth of field, making it ideal for creating images with beautifully blurred backgrounds. Its optical excellence is underscored by a sophisticated design featuring three FLD elements, two SLD elements, and an aspherical element, ensuring sharp, high-contrast images with minimal chromatic aberrations. The lens's Hyper Sonic AF motor delivers fast, quiet, and precise autofocus, enhancing its suitability for dynamic photography scenarios such as weddings, portraits, and events. Additionally, its weather-sealed construction and durable build, including a metal barrel, ensure reliability and longevity. With its compatibility across multiple mounts including Canon EF, Nikon F, Sony E, and L-mount, and the option to fine-tune performance via the Sigma USB Dock, the Sigma 105mm F1.4 DG HSM Art Lens is a versatile and robust tool for serious photographers.

More Details:

• Exceptional peripheral brightness - With its large filter diameter of 105mm, this lens delivers a significantly greater volume of peripheral light than other lenses in its class. Minimizing vignetting while offering a beautiful bokeh effect, this lens is ideal for portrait photography.
• 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 reduces flare and ghosting to help photographers produce sharp and high-contrast images even in backlit conditions. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.
• Fast AF with 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.
• 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.
• Three FLD Elements, Two SLD Elements
• One Aspherical Element
