The Sigma 135mm f/1.8 DG HSM Art is a medium telephoto prime lens designed for modern high megapixel DSLR cameras. A new large Hyper Sonic Motor produces significant torque to the focusing group for better speed while the acceleration sensor detects the position of the lens and compensates for such factors as gravity to help aid in focusing performance. This state-of-the-art prime lens touts a dust and splash proof construction 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 135m f/1.8 Art the ideal portrait lens while its large aperture help with event photography and much more. Like each and every Global Vision Lens, the Sigma 135mm f/1.8 DG HSM Art is handcrafted at our single factory in Aizu, Japan and undergoes individual evaluation before leaving Sigma’s facility.
To deliver the ultra-high resolution that brings the best out of 50 Megapixel 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 centre to the edges of the image. By minimising distortion as well, the lens delivers impeccable image quality—no need for digital adjustment during image processing.
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 an f/1.8 aperture 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 large hypersonic motor (HSM) offers two benefits. It delivers ample torque to the focusing group for outstanding speed, ensuring exceptionally stable performance even at lower speeds. The acceleration sensor detects the orientation of the lens, allowing the autofocus system to respond to varying loads on the focusing group due to gravity. Along with the optimised AF algorithm, these features deliver fast autofocus photography. In addition, the focus limiter makes AF highly responsive to distance from the subject for even more nimble performance.
