Laowa's fast full-frame 15mm — f/2 with Zero-D distortion correction and filter thread.
The Laowa 15mm f/2 Zero-D is an ultra-wide prime designed for near-zero distortion at 15mm — the Zero-D (Zero Distortion) designation indicates the lens is corrected for minimal barrel distortion compared to typical ultra-wide designs. Manual focus only. L-Mount.
f/2 maximum aperture. 15mm focal length. Zero-D (near-zero distortion). L-Mount. Manual focus only. Full-frame coverage. At approximately 560g. 72mm filter thread.
The Zero-D correction is the defining feature: most ultra-wide lenses, especially below 20mm, exhibit notable barrel distortion that requires software correction. The Laowa 15mm f/2 Zero-D corrects this optically, producing straight horizon lines and architectural verticals without post-processing distortion correction. Suited to architecture and interior photography where distortion correction in post is undesirable.
On the used market the Laowa 15mm f/2 Zero-D L-Mount is an affordable manual-focus ultra-wide for L-Mount cameras (Leica SL, Panasonic S, Sigma FP). Condition checks: L-Mount contacts, focus ring smoothness, front element for marks, 72mm filter thread condition. Manual focus only — no AF.
