Sigma 105mm f/1.4 DG HSM Art

Get Sigma 105mm f/1.4 DG HSM Art for Canon, Nikon, Sony mirrorless at B&H Photo.

The Sigma 105mm f/1.4 DG HSM Art debuts in June 2018, and is available for Nikon, Canon, Sigma SA, and Sony mirrorless for about $1599. It offers very high lens speed at the 105mm focal length while claiming outstanding performance.

  • Full-frame for Nikon, Canon, Sigma SA and Sony mirrorless.
  • Aperture Range: f/1.4 to f/16
  • Three FLD Elements, Two SLD Elements
  • One Aspherical Element
  • Super Multi-Layer Coating
  • Hyper Sonic AF Motor, Manual Override
  • Weather-Sealed, Protective Front Coating
  • Rounded 9-Blade Diaphragm
  • Removable Rotating Arca-Type Tripod Foot
  • Compatible with Sigma USB Dock

The Sigma 105/1.4A looks like another effort from Sigma that sets the new standard among autofocus lenses, both for lens speed and performance. Indeed, it may be the best effort yet among the Sigma Art lens line. Quite possibly this will be an “Otus grade” lens. The very large 105mm front element surely serves more purposes than just keeping vignetting minimal.

I’m looking forward to shooting the new Sigma 105mm f/1.4 DG HSM Art, which should become available in mid-June, first for Nikon and Canon with a Sony mirrorless version coming later. Sigma states that the optics are identical.

Since I’ll be testing it in Nikon mount, I’ll be reviewing it in diglloyd Advanced Photography; late when the Sony version arrives I may give it a go on Sony.

Sigma 105mm f/1.4 DG HSM Art

Leading the way in F1.4 brightness

The flagship of the F1.4 Art series—

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 performance TBD, but is expected to be extremely high, as with the Sigma 135mm f/1.8A.

Specifications

In what might be a first, Sigma has built in the dovetail required for mounting in a Arca-Type clamp (tripod head). Kudos to Sigma; this is something I’ve been noting for years as really dumb from Nikon and Canon and Sony.

Nominal except as noted. Sigma offers a 3-year warranty extension on top of the 1 year warranty for USA users—excellent, at least if one is in the USA.

The Nikon mount version of this lens includes an electromagnetic diaphragm mechanism.

SIGMA 105mm F1.4 DG HSM Art

Leading the way in F1.4 brightness

The flagship of the F1.4 Art series: 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

Ideal for portrait and astro photographies 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. 

Exclusive low-dispersion glass

The 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 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.

Compatible with Canon Lens Aberration Correction

The Canon mount version of this lens is compatible with the Canon Lens Aberration Correction function.* Matching the optical characteristics of the lens, this function performs in-camera corrections of peripheral illumination, chromatic aberrations, distortion, and more, to further enhance image quality. * Function not available on all Canon cameras. Available corrections may vary depending on the Canon camera model.

Professional specifications

Allowing photographers to work in all types of weather Like SIGMA’s Sports line lenses (Move to our YouTube page), 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 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.

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.

Compatible with Mount Converter MC-11*

SIGMA and Canon mount lenses Mount Converter MC-11 allows you to use your SIGMA SA mount and SIGMA EOS mount (Canon-compatible) interchangeable lenses with the Sony E-mount camera body.

Compatible with full-frame Sony E-mount cameras

he version of this lens compatible with Sony E-mount mirrorless cameras contains the same optical system as for SLRs. 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. In addition, the lens is compatible with Sony’s Continuous AF, which is not addressed by MOUNT CONVERTER MC-11. SIGMA plans to offer over time Sony E-mount versions of every full-frame prime lens currently available in the Art line, from 14mm to 135mm.
