SIGMA 135mm f/1.8 DG HSM Art Lens Compatible with L Mount

Optimal image quality for ultra-high megapixel cameras: To deliver the ultra-high resolution that makes the most of ultra-high megapixel cameras of 50 MP or higher, the focus mechanism features the floating system of Sigma. Fast and agile autofocus photography: The large HSM (Hypersonic Motor) motor provides sufficient torque to the focus group for exceptional speed, ensuring exceptionally stable performance, even at low speeds. Ideal for portraits requiring spectacular bokeh: The 135mm focal length produces a stunning compression effect: even at a fairly close distance from the subject, the telephoto ring allows the photographer to establish a variety of spectacular perspectives. The compression effect really shines both in close-ups and in full portraits, making composing easier.
