More Info

The 19mm f/2.8 EX DN Lens for Sony E Mount Camera from Sigma is a Digital Neo (DN) lens specifically designed for mirrorless interchangeable lens cameras. On a Sony E mount camera (NEX), its focal length is equivalent to 28.5mm. It has a newly developed linear AF motor for swift and accurate autofocus, making it ideal for video as well as still photography.

Three glass mold aspherical lenses offer excellent correction for distortion, color aberration and field curvature. The inner focusing system corrects the fluctuation of aberration to maintain image quality regardless of the focal distance. Multi-layer coating reduces flare and ghosting, and provides sharp and contrasty images even at the maximum aperture. The seven blades of the diaphragm produce a pleasing quality in the out-of-focus areas of an image (bokeh).
