Sigma 19mm f/2.8 EX DN E Autofocus Lens for Sony E-Mount {46}

Sigma 19mm f/1.4 EX DN is a high-performance wide-angle lens structured exclusively for mirrorless interchangeable lens cameras.  It has the equivalent angle of view as a 28.5mm (35mm equivalent focal length) on the E-mount systems. Three glass mold aspherical lenses deliver superior correction for distortion, color aberration and field curvature. The inner focusing system corrects the fluctuation of aberration to preserve image quality at all focal lengths. Sigma's Super Multi-Layer Coating minimizes flare and ghosting and provides sharp and high contrast images at all apertures. The superior telecentric optical design enhances overall image quality throughout the frame. The lens benefits from a linear AF motor which moves the lens elements directly without the need for gears or the drive of other mechanical parts. The technology of the AF motor ensures accurate and quiet autofocusing, making the lens suitable for video recording as well as still photos.
