Fast f/1.4 Aperture Telephoto. The Sigma 135mm f/1.4 DG Art for L-Mount’s bright f/1.4 maximum aperture and rounded, thirteen-blade diaphragm combine to provide shallow depth of field, smooth bokeh, and selective focusing, making this lens ideal for portraiture, low-light shooting, and other artistic applications. You can also use this lens on APS-C models, on which it’ll provide a 206.8mm equivalent focal length.
High-Quality Optics. As a part of Sigma’s Art lens line, the 135mm f/1.4 goes through rigorous testing to ensure high image quality. Four “F” Low-Dispersion elements and two Super Low-Dispersion glass elements correct for chromatic aberrations and color fringing while ensuring high image sharpness, clarity, and contrast. The Super Multi-Layer Coating minimizes lens flare and ghosting, helping to provide high contrast, even in strong lighting.
HLA-Driven AF Motor. The HLA-driven, high-speed autofocus motor system provides fast, smooth, and quiet operation in a broad range of shooting situations. You can also manually override the autofocus motor at any time by rotating the focusing ring, giving you quick fine-tuning ability.
