Sigma 105mm F1.4 DG HSM | Art lens: The Bokeh Master for Canon

SIGMA 105mm F1.4 DG HSM 

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.

The Sigma 105mm F1.4 DG HSM | Art lens joins the line of Art lenses as the longest-focal length F1.4 lens. This full-frame lens pairs outstanding resolution with beautiful bokeh and exceptional peripheral brightness thanks to Sigma’s optical design. The 105mm F1.4 DG HSM | Art lens features a highly effective dust- and splash-proof construction.

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. 

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. 

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 

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. 

Canon EF Mount

The Canon EF mount version of the lens is compatible with Canon Lens Aberration Correction performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality.
