Sigma 105mm F1.4 Art Lens: A Portrait Photographer's Dream

Overview:

The Sigma 105mm F1.4 DG HSM Art Lens stands out as a top-tier choice for Canon EF-mount camera users, especially favored by portrait photographers and professionals for its outstanding image quality and fast aperture. This lens is a masterpiece in Sigma's Art line, showcasing an advanced optical design with FLD and SLD glass elements that significantly reduce chromatic aberrations, ensuring sharp, clear, and color-accurate images. Its fast f/1.4 aperture is not only ideal for low-light conditions but also creates beautiful bokeh effects, making it perfect for isolating subjects against dreamy backgrounds. The lens's robust, weather-sealed construction adds to its reliability in various shooting environments. While its Hyper Sonic AF Motor ensures quick and quiet autofocus, the lack of image stabilization is typical for prime lenses. Weighing 1645g, it's on the heavier side, and its unique 105mm filter diameter may require specific filters. Despite these considerations, the Sigma 105mm F1.4 DG HSM Art Lens is an exceptional choice for those seeking premium optical performance in portraiture, weddings, and event photography.

• 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.
