USED Sigma 17mm F4 DG DN Contemporary for Sony E

Product Features

• The lens construction utilizes two SLD glass elements and three aspherical lens elements. By employing an aspherical lens not only at the front but also at the rear, close to the image sensor, aberrations are well corrected while keeping the body size compact.
• A minimum focusing distance of 12cm is another significant feature of this lens. Since it can focus at close distances, it is suitable for selfies that incorporate the background or for shooting close-up subjects.
• The AF drive system employs a quiet and high-speed stepping motor, allowing for comfortable shooting of both stills and videos. With a design that considers flare and ghosting, clear shots are possible in any environment, even with this ultra-wide-angle lens where light sources are prone to entering.
• Features a metal exterior, common to the series. Parts made of machined aluminum are not only beautiful but also contribute to the product's refined quality with solid rigidity and high durability.
• Internal structures that slide with the operation ring also use metal materials. High-precision parts, made possible by advanced metalworking technology backed by the professional cinema lens "SIGMA CINE LENS," achieve a supreme texture at each operating part that makes you want to use it repeatedly.
