Sigma 135mm f1.4 DG Art Lens for Sony E

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.
