Request InfoSigma Corp. of AmericaThe 135-mm ƒ1.8 DG HSM Art Lens from Sigma Corp. of America is a mid-range telephoto prime lens with a greater shallow depth of field and isolation of subjects. A compression effect makes it equally as powerful for up-close and full-length portraits. Its Hyper Sonic Motor delivers ample torque to the focusing group for outstanding speed, ensuring exceptionally stable performance even at lower speeds and for fast autofocus photography. Top performance is provided from the center to the edges of the image due to the signature floating system of the lens focus mechanism.
