The Sigma 135mm f1.4 DG Art is the world's first 135mm autofocus lens with an f1.4 aperture, designed for full-frame mirrorless systems. Its 17-element, 13-group optical construction delivers crisp detail, while a 13-blade diaphragm produces large, natural bokeh. Dual HLA motors and a floating focus system ensure precise autofocus in a robust, dust- and splash-resistant build with an Arca-Swiss tripod socket and a declickable aperture ring for tactile adjustments.
