Sigma 105mm f1.4 DG HSM Art Lens for L Mount

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 - the flagship of the F1.4 Art series - SIGMA has designed this lens 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 colours, 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.

Exclusive low-dispersion glass - The degree to which light is refracted by glass depends on the light’s wavelength. This fact causes different colours of light to focus at slightly different points. The result is chromatic aberration, the colour 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 of power distribution gives SIGMA lenses superlative image rendition undiminished by residual chromatic aberration.

Designed to minimize flare and ghosting - From 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.

Allowing photographers to work in all types of weather - 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, 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.

Ease-of-use specifications - Instead of conventional ABS plastic, the exclusive lens hood features CFRP (carbon fibre 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.

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.

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.

SIGMA USB DOCK for SIGMA GLOBAL VISION lenses (sold separately) - With the optional SIGMA USB DOCK, you can update your lens firmware and adjust the focus position and other settings. Simply connect the lens to the SIGMA USB DOCK and the dock to a computer to use the dedicated SIGMA Optimization Pro software and perform various types of customization and adjustment.
