Overview
The Sigma 135mm f/1.8 DG HSM Art Lens is an easy-to-use, optically advanced lens that lets you take crystal clear pictures with your Nikon F-mount camera. The optical construction of the lens consists of 13 elements in 10 groups. Also included are two FLD elements and two SLD elements that reduce color fringing and chromatic aberrations, so that you get better clarity and color accuracy. The Super Multi-Layer Coating on the lens minimizes ghosting and flares to produce neutral colors and a rich contrast, even when there is backlight. The large Hyper Sonic Motor lets the lens get a quick, accurate autofocus. Moreover, the nine-blade, rounded diaphragm is useful for producing a smooth bokeh for your subject’s background. The firmware and characteristics of the lens can be updated and fine-tuned, respectively, with the separately available Sigma USB Dock. The Sigma 135 mm Art Lens is made from a Thermally Stable Composite material and conventional metals, and features a high-quality rubber sealing on the brass bayonet mount for protection from splashes and dust.
