The new standard in 135mm telephoto lenses
135mm telephoto lenses are often categorized as the foundational telephoto, the first one to add to a lens collection. This focal length delivers a strong perspective compression effect, while the large diameter with F1.8 brightness provides a dramatic bokeh effect. By minimizing axial chromatic aberration, the SIGMA 135mm F1.8 DG HSM | Art makes this bokeh effect not only impressive but also beautiful while delivering superb contrast and sharp image quality in every shot. It offers the outstanding resolution required for 50MP or higher ultra-high-megapixel DSLRs. By incorporating its latest innovations in design and optical glass and rethinking every aspect of the lens, SIGMA has ensured outstanding image quality all the way to the edges, establishing the new standard in 135mm telephoto lenses.
Art line delivers high-level artistic expression
SIGMA is organizing all its interchangeable lenses into three product lines: Contemporary, Art, and Sports, each with a distinctive concept. Designed with a focus on sophisticated optical performance and abundant expressive power, Art line lenses deliver high-level artistic expression. Offering astonishing rendering performance that meets the highest standard, they are perfect for landscapes, portraits, still-lifes, close-ups, and casual snaps. They are made for the kind of photography that unleashes the inner artist. A powerful ally in every genre of photography, SIGMA's Art line lenses excel both in the studio for formal works and outdoors for impressive shots of architecture, starry skies, and many other scenes.
Designed to prioritize optical performance-with absolutely no compromises
Outstanding resolving power and minimized chromatic aberrations help make this the ultimate lens for portraits.
With resolution so crystal-clear that individual hairs can be discerned in a portrait, this large-diameter lens also delivers a beautiful bokeh effect, giving photographers everything they need. It performs better than typical large-diameter standard to medium telephoto lenses in producing close-ups and full-body shots in which the subject stands out against a pleasantly blurred background.
Optical design delivering ultra-high-resolution and minimized chromatic aberrations
In addition to an optimized power distribution, this lens features two SLD (Super Low Dispersion) glass elements and two FLD ("F" Low Dispersion) glass elements. These technologies help minimize chromatic aberrations, which tend to appear in the bokeh area outside of focus in portraits, as well as on slender objects such as fine branches. The end result is ultra-high resolution and clarity throughout the image, even at wide-open aperture.
Ideal for portraits requiring a dramatic bokeh effect
The 135mm focal length delivers a stunning compression effect: even fairly close to the subject, the telephoto ring allows the photographer to establish a variety of dramatic perspectives. The compression effect truly shines in both close-ups and full-length portraits, making composition easy. Moreover, the large diameter with F1.8 brightness makes possible a body shot with an impressive bokeh background. In sum, this lens puts a full menu of compositional options at the photographer's fingertips.
The Art line's sixth large-diameter prime lens for cameras with full frame sensors
The Art line was launched in 2012 with the SIGMA 35mm F1.4 DG HSM | Art as its first lens. Since then, the line has come to encompass a wide variety of lenses, and the new SIGMA 135mm F1.8 DG HSM|Art is the line's sixth large-diameter prime for cameras with full-frame sensors. It sets a new standard for prime lenses in the ultra-high-megapixel era.
Image quality optimal for ultra-high-megapixel DSLRs
To deliver the ultra-high resolution that brings the best out of 50MP or higher ultra-high-megapixel DSLRs, the focus mechanism features SIGMA's floating system. No matter what the distance from the subject, this lens offers top performance from the center to the edges of the image. By minimizing distortion as well, the lens delivers impeccable image quality-no need for digital adjustment during image processing.
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 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 provide sharp, high-contrast images even in backlit conditions.
Leveraging SIGMA's latest technologies - Large HSM, dust/splash-proof construction, and more
To achieve both outstanding optical performance and satisfying usability, this lens features the latest SIGMA technologies, including a large hypersonic motor (HSM), dust- and splash-proof construction, and other high-quality features.
The large HSM delivers highly responsive autofocus
The large hypersonic motor (HSM) delivers ample torque to the focusing group for utstanding speed, ensuring exceptionally stable performance even at lower speeds. Along with the optimized AF algorithm, this feature delivers fast autofocus photography. In addition, the focus limiter makes AF highly responsive to distance from the subject for even more nimble performance.
The 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.

New SIGMA GLOBAL VISION product lines are setting new benchmarks for image quality Evaluation with SIGMA's own MTF measuring system: A1
Sigma used to measure lens performance with a Modulation Transfer Function (MTF) measuring system using conventional sensors. However, they have developed their own proprietary MTF measuring system (A1) using 46-megapixel Foveon direct image sensors. Even previously undetectable high-frequency details are now within the scope of Sigma quality control inspections. All SIGMA 135mm F1.8 DG HSM | Art lenses are checked using this A1 system before they are shipped.
46-megapixel Foveon direct image sensor
The 46 effective megapixel (4,800 x 3,200 x 3 layers) and 44 recording megapixel (4,704 x 3,136 x 3 layers) 23.5 x 15.7mm APS-C X3 direct image sensor captures all primary RGB colors at each and every pixel location, ensuring the capture of full and complete color. Using three silicon-embedded layers of photo detectors, stacked vertically to take advantage of silicon's ability to absorb red, green and blue light at different respective depths, it efficiently reproduces color more accurately, and offers sharper resolution, pixel for pixel, than any conventional image sensor. Since color moire is not generated, the use of a low-pass filter is not required, meaning light and color, generated by the 46-megapixel APS-C X3 direct image sensor is captured with a three-dimensional feel.
