Sigma 135mm f/1.8 ART DG HSM Lens (for Sony Alpha E-Mount Cameras)
The ultimate 135mm telephoto
The Sigma 135mm f/1.8 ART DG HSM Lens is a medium range telephoto prime lens designed for modern high megapixel cameras. A large Hyper Sonic Motor (HSM) delivers ample torque to the focusing group for outstanding speed, ensuring exceptionally stable performance even at lower speeds.
This state-of-the-art prime lens touts a dust and splash proof mount for guaranteed performance in any condition, and its large f/1.8 aperture allows for more creative control over imagery. A stunning compression effect makes the Sigma 135mm f/1.8 Art the ideal portrait lens while its large aperture helps with event photography and much more.
Like each and every Global Vision Lens, the 135mm f/1.8 DG HSM Art is handcrafted at Sigma's single factory in Aizu, Japan and undergoes individual evaluation before leaving the facility.
Image quality optimal for ultra-high-megapixel cameras:
To deliver the ultra-high resolution that brings the best out of 50MP or higher ultra-high-megapixel cameras, 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.
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 a wide-open aperture.
Fast and nimble autofocus photography:
The large HSM (Hyper-Sonic Motor) 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. In addition, the focus limiter makes AF highly responsive to distance from the subject for even more nimble performance.
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 f/1.8 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 9-blade rounded diaphragm creates an attractive blur in the out-of-focus areas of the image.
Exclusive low-dispersion glass:
This lens features two types of exclusive low-dispersion glass offering superior performance: 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.
