Introducing the “bokeh master” featuring incredible resolution and designed for full-frame sensors this is the longest focal length of the Art line’s F1.4 lenses . Leading the way in F1.4 brightness Since introducing its first SIGMA Global Vision F1.4 lens in 2012 the 35mm F1.4 DG HSM | Art SIGMA has been adding wide-aperture F1.4 options to the lineup. 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. Optical system delivering unsurpassed F1.4 performance In 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. Exceptional peripheral brightness The 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. Professional specifications Like SIGMA’s Sports line lenses the 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 cover connection and other areas 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. Ease-of-use specifications Instead 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. Compatible with full-frame Sony E-mount cameras The Sony E-mount version of this lens is compatible with Sony mirrorless cameras and contains the same optical system as the versions for other mounts. SIGMA MOUNT CONVERTER MC-11 is not required as the lens performs the same functions as the converter including in-camera image stabilization and in-camera lens aberration correction. SIGMA plans eventually to offer Sony E-mount versions of every full-frame prime lens currently available in the Art line from 14mm to 135mm.
