What is the sigma 19mm f 2 8 dn art good for?

The Sigma 19mm f/2.8 DN Art is a cheap, light wide prime from 2013. It's a good choice if you want a wide view without carrying much weight. On an APS-C Sony E body it frames like a 28mm on full frame, which suits street, travel and documentary work. Its f/2.8 aperture gives about the depth of field of f/4.2 there. On Micro Four Thirds it frames like a 38mm on full frame, which keeps a compact kit small.

It has autofocus but no stabilisation, so it works best in decent light or at a fast shutter speed.

Good pairings from the catalogue:

• Sony a6400 for a small APS-C kit
• OM System OM-5 for a compact Micro Four Thirds setup
• Sony a7 III if you want it on a full-frame body in APS-C crop mode
