Laowa's fast full-frame 15mm — f/2 with Zero-D distortion correction and filter thread.
The Laowa 15mm f/2 Zero-D is a fast ultra-wide prime for full-frame with near-zero distortion — the Zero-D designation. At 15mm f/2 it provides ultra-wide coverage with a fast aperture useful for astrophotography, plus a filter thread.
Optically impressive — near-zero distortion at 15mm is remarkable. Sharp from f/4 with the fast f/2 useful for night sky photography. The Zero-D correction makes this excellent for architecture where straight lines must remain straight.
Available for Canon EF, Nikon F, and Sony FE. 72mm filter thread — accepts standard screw-on filters at 15mm, a major practical advantage. Manual focus only. No electronic contacts. Approximately 500g.
Available used at mid-range prices. The 72mm filter thread at 15mm full-frame is exceptional — allows ND and polariser use at ultra-wide. The f/2 speed and zero distortion are unique. For architecture and astro photographers.
