Sigma Lens 17mm F4 DG DN L Mount Single Focus Wide Angle Full Size for Mirrorless Contemporary

Adopts 2 SLD glasses and 3 aspherical lenses. By using an aspherical lens not only in the first lens, but also in the last lens near the image sensor, we are able to keep the body size down while effectively correcting aberrations. Another major feature of this lens is its short minimum focusing distance of 12cm. Since it focuses even at close distances, it is suitable for selfies that incorporate the background or shots of the subject at hand. Adopts a metal exterior with common specifications for the I series. Parts made from machined aluminum are not only beautiful, but also improve the quality of the product itself, with solid rigidity and high durability.
