Type: SIGMA 30mm f/1.4 DC DN Contemporary Lens for Sony Mirrorless Cameras and APS-C format e-mount The lens is made in Brazil and features a maximum aperture of f/1.4, high-quality optical design with aspherical and high-refractive index elements, and a stepping AF motor for smooth, near-silent autofocus.
Love this lens. Awesome under indoor light conditions, amazing bokeh at 1.4. The only lens I really use now. Worth the price difference from the 50mm 1.8, much much better construction.
