A fast telephoto prime, the Canon EF-mount Sigma 135mm f/1.8 DG HSM pairs bright and sophisticated optics with intuitive handling and design. As part of the Art line of lenses, this 135mm f/1.8 is designed for high-resolution rendering, and utilizes FLD and SLD glass to control chromatic aberrations and color fringing for notable clarity. A Super Multi-Layer Coating also enhances image quality by suppressing lens flare and ghosting for improved contrast and color fidelity in strong lighting conditions. Additionally, making it an ideal lens for portraiture, the bright f/1.8 maximum aperture pairs with a rounded nine-blade diaphragm to benefit selective focus and shallow depth of field imaging with smooth bokeh.
