135mm focal length delivers a strong perspective compression effect, while the large diameter with f/1.8 brightness provides a dramatic bokeh effect. By minimizing axial chromatic aberration, the SIGMA 135mm F1.8 DG HSM Art Lens 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 megapixel DSLRs.

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 is ideal for close-ups and full-body shots, with subjects standing out against a pleasantly blurred background. In addition to standard portraits, this lens is a top performer for live events, with its super-fast autofocus capturing subjects with ease.

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.

Fast autofocus
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 F1.8 brightness makes possible a body shot with an impressive bokeh background. In sum, this lens puts a full menu of composition options at the photographer’s fingertips.
