Description

Details

Both fast and wide, the Sigma 14mm F1.8 Art DG HSM, L Mount from Sigma is a unique wide-angle prime designed to produce high-resolution, well-corrected imagery. As part of the Art line of lenses, this lens has a focus on image quality and rendering and utilizes both FLD and SLD glass elements to control chromatic aberrations and color fringing for notable clarity. Four aspherical elements, including the front large-diameter precision-molded glass element, also contribute to reducing distortion and spherical aberrations for improved sharpness and accuracy. Additionally, a Super Multi-Layer Coating has been applied to individual elements to suppress lens flare and ghosting for greater contrast when working in strong lighting. Well-suited to astrophotography and low-light outdoor shooting, this lens presents a unique blend of a broad perspective and fast, flexible performance.

Sigma 14mm F1.8 Art DG HSM, L Mount Features

14mm ultra-wide-angle and F1.8 brightness: a new dimension of visual experience

A mode of expression that was unavailable—until now

Minimized chromatic aberrations

Three FLD (“F” Low Dispersion) glass elements and four SLD (Super Low Dispersion) glass elements help minimize transverse chromatic aberration, which tends to be noticeable in shots taken with ultra-wide-angle lenses. Offering excellent peripheral brightness, this lens delivers outstanding image quality from the center to the edges.

Minimized distortion

Serving as the front lens element, the large φ80mm precision-molded glass aspherical lens effectively minimizes distortion. Offering excellent peripheral brightness, this lens delivers outstanding image quality from the center to the edges.

Featuring a large-diameter aspherical lens element

The SIGMA 12-24mmF4 DG HSM | Art was the first SIGMA lens to feature a large φ80mm aspherical lens element. Building on the expertise derived from this success, the new lens features a large ⌀80mm precision-molded glass aspherical lens as its front element. This technology has made possible the 14mm F1.8 specification—the first of its kind.

Distinctive bokeh effect

Even at the 14mm ultra-wide-angle of view, F1.8 brightness makes possible a very shallow depth of field with the subject standing out dramatically against a bokeh background. It’s the unique mode of expression that only a large-diameter lens can deliver.

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 a superlative image rendition undiminished by residual chromatic aberration.

Designed to minimize flare and ghosting

From the start of the design process, SIGMA measured flare and ghosting to establish an optical design that is resistant to strong incidental light sources such as backlight. At the prototyping stage, SIGMA used not only simulations but actual photographic experiments to assess flare and ghosting under multiple criteria, identify the causes of these issues under a wide range of situations, and take measures to mitigate them. In addition, SIGMA’s Super Multi-Layer Coating helps further reduce flare and ghosting and provides sharp, high-contrast images even in backlit conditions.

Delivering fast autofocus photography

An ultra-wide-angle lens that gives the photographer satisfies the control

A large HSM, AF with a full-time manual focus, and all of SIGMA’s latest design and manufacturing technologies help deliver an entirely new visual experience.

The large HSM delivers highly responsive autofocus

The large hypersonic motor (HSM) delivers ample torque to the focusing group for outstanding speed, ensuring exceptionally stable performance even at lower speeds. Along with the optimized AF algorithm, this feature delivers fast autofocus photography.

Fast AF with full-time manual focus

The full-time manual focus function allows the lens to be switched to manual focus simply by rotating the focus ring.

Nikon electromagnetic diaphragm mechanism included

The Nikon mount version of this lens includes an electromagnetic diaphragm mechanism that allows it to receive the appropriate signals from the camera body. This feature ensures precision diaphragm control and stable Auto Exposure (AE) performance during continuous shooting. Nikon camera compatibility

Mount with Dust and Splash Resistant Structure

Since the area of the lens most vulnerable to dust and other foreign bodies is the mount, rubber sealing* helps provide peace of mind. In addition, the front lens element features a water- and oil-repellant coating that helps the lens perform well in the rain, near water, and in other challenging conditions.

Rounded diaphragm

The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
