Sigma 135mm F1.4 DG | Art Sigma's craftsmanship is behind the beautiful bokeh. A 13-blade diaphragm maintains a circular bokeh shape, while exceptional precision in aspherical lens processing further enhances its smoothness. This beautiful, natural bokeh is the result of Sigma's know-how gained through the development of F1.4 prime lenses over many years and the advanced manufacturing technology cultivated at its Aizu factory.
