Is the sirui sniper 16mm f 1 2 good for video?
The Sirui Sniper 16mm f/1.2 can work for video, but it's not a clear winner, and the choice depends on what you shoot. It's an autofocus prime, and on APS-C it frames like a 24mm lens on full frame. That's a little tight for the arm's-length vlogging I usually suggest. My video guide recommends roughly 16-20mm full-frame equivalent, so this lens sits outside that range.
It's also not stabilised, so keep that in mind for handheld work. The f/1.2 aperture gives very shallow depth of field, which looks lovely for talking heads and low light.
Check the camera body too. A flip-out screen and a microphone input matter as much as the lens, so read the audio notes before you buy. The lens page is here.
