Review Lens: Sigma 19mm F2.8 EX DN Sony E

Lens Overview - Sigma 19mm F2.8

A comfortable wide-angle field of view along with a compact design, the silver Sigma 19mm f/2.8 DN Art is a sleek and portable prime lens designed for Micro Four Thirds mirrorless cameras. Its optical design incorporates three aspherical elements, which greatly reduce spherical aberrations and distortion for notable sharpness and highly accurate rendering. A Super Multi-Layer Coating is also featured and minimizes flare and ghosting for heightened contrast and color accuracy when working in strong lighting conditions. Complementing the optics is a Linear AF motor, which realizes smooth and quiet autofocus performance, and a rounded seven-blade diaphragm contributes to a pleasing bokeh quality.

Wide-angle prime is designed for Micro Four Thirds mirrorless cameras and provides a 38mm equivalent focal length.
The f/2.8 maximum aperture strikes a balance between being bright enough to suit working in available light situations while also promoting a lightweight, compact form factor.
Three aspherical elements help to control spherical aberrations and distortion to help realize greater sharpness and more accurate rendering.
A Super Multi-Layer Coating has been applied to lens elements in order to minimize lens flare and ghosting and contribute to producing contrast-rich and color-neutral imagery, even in backlit conditions.
Linear AF motor achieves especially quiet and accurate autofocus performance that is suitable for both photo and video applications.
Brass bayonet affords improved mounting accuracy and rigidity.
Rounded seven-blade diaphragm contributes to a pleasing bokeh quality.
