Now, with the introduction of the new 105mm F1.4 DG HSM | Art, SIGMA offers a total of nine lenses with F1.4 brightness, including six for full-frame cameras and three for APS-C cameras. SIGMA has designed all of these lenses to offer minimal optical aberration and deliver incredible resolution and stunning contrast. Boasting the longest focal length of the F1.4 Art line lenses, the new lens combines outstanding resolution with a beautiful bokeh effect. Designed with great care to ensure that both the in-focus and out-of-focus areas of the photograph are equally satisfying to the eye, this lens is truly a “bokeh master.” The SIGMA 105mm F1.4 DG HSM | Art has earned its place as the flagship of the F1.4 Art line lenses, prioritizing image quality above all to fulfill the promise of the line, delivering truly amazing optical performance. \u003c\/p\u003e\n\u003ch4\u003eOptical system delivering unsurpassed F1.4 performance\u003c\/h4\u003e\n\u003ch4\u003eIdeal for portrait and astro photographies\u003c\/h4\u003e\n\u003cp\u003eIn order to combine outstanding wide-aperture, mid-telephoto performance with F1.4 brightness at maximum aperture, this lens incorporates 17 optical elements in 12 groups—an uncommonly large number of elements for a prime lens. By including three FLD glass elements, two SLD glass elements, and one aspherical lens element, the optical system minimizes axial chromatic aberration to deliver extremely high resolution along with ample peripheral light volume. The area in focus is extremely sharp, while the area out of focus features a beautiful bokeh effect with highly natural colors, making this lens a powerful choice for portrait photography. The optical system also minimizes sagittal coma flare, making this lens excellent for capturing starry skies.\u003c\/p\u003e\n\u003ch4\u003eExceptional peripheral brightness\u003c\/h4\u003e\n\u003cp\u003eThe most effective method of ensuring ample light is to maximize the diameter of the first element of the optical system. With its large filter diameter of 105mm, the SIGMA 105mm F1.4 DG HSM | Art 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. \u003c\/p\u003e\n\u003ch4\u003eExclusive low-dispersion glass\u003c\/h4\u003e\n\u003cp\u003eThe degree to which light is refracted by glass depends on the light's wavelength. This fact causes different colors of light to focus at slightly different points. The result is chromatic aberration, the color fringing that is particularly noticeable in telephoto lenses. 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. Meticulous deployment of these types of exclusive low-dispersion glass and optimization ofpower distribution gives SIGMA lenses superlative image rendition undiminished by residual chromatic aberration.\u003c\/p\u003e\n\u003ch4\u003eDesigned to minimize flare and ghosting\u003c\/h4\u003e\n\u003cp\u003eFrom 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. The included lens hood can be attached to block out extraneous light, which can have a negative effect on rendering performance.\u003c\/p\u003e\n\u003ch4\u003eProfessional specifications\u003c\/h4\u003e\n\u003cp\u003ethe 105mm F1.4 DG HSM | Art features a highly effective dust- and splash-proof structure with special sealing at the mount connection, manual focus ring, zoom ring, and cover connection, allowing photographers to work in all types of weather. In addition, the front of the lens is protected by a water- and oil-repellent coating that makes cleaning easy. The high-speed, high-accuracy autofocus helps photographers react in an instant to get those special shots.\u003c\/p\u003e\n\u003ch4\u003eEase-of-use specifications\u003c\/h4\u003e\n\u003cp\u003eInstead of conventional ABS plastic, the exclusive lens hood features CFRP (carbon fiber reinforced plastic), a light but strong material used in the interior and exterior fittings of aircraft, among many other applications. The removable Arca-Swiss tripod socket is compatible with Arca-Swiss platforms and clamps, and its exclusive protective cover makes the lens easier to carry and use when shooting hand-held.\u003c\/p\u003e\n\u003ch4\u003eFast AF with full-time manual focus\u003c\/h4\u003e\n\u003cp\u003eFull-time manual focus function allows the lens to be switched to manual focus simply by rotating the focus ring.\u003c\/p\u003e\n\u003ch4\u003eHigh-precision, rugged brass bayonet mount\u003c\/h4\u003e\n\u003cp\u003eThe brass mount combines high precision with rugged construction. Its treated surfaces and enhanced strength contribute to the exceptional durability of the lens.\u003c\/p\u003e\n\u003ch4\u003eRounded diaphragm\u003c\/h4\u003e\n\u003cp\u003eThe 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.\u003c\/p\u003e\n\u003ch5\u003eSpecifications\u003c\/h5\u003e\n\u003cp\u003eThe Sigma AF 105mm DG HSM Art Lens delivers unsurpassed F1.4 performance and 'exceptional peripheral brightness. This lens is also designed for high-resolution rendering, and utilizes FLD and SLD glass to control chromatic aberrations.
