Thirteen elements in 8 groups (2 ED + 2 aspherical elements). Five aperture blades. The 67mm filter thread. At 360g the lens is lightweight for a 14mm prime. Minimum focus distance of 0.145m. Manual focus only. f/4 maximum aperture. Full-frame coverage. Nikon F mount.
The Zero-D designation indicates minimal barrel distortion: conventional 14mm lenses exhibit significant barrel distortion at 14mm that requires correction in post-processing. The Zero-D design corrects this optically in the lens formula, providing more architecturally accurate straight lines without post-processing. The 67mm filter thread accepts standard filters — unlike the bulging front elements of some 14mm designs.
On the used market the Laowa 14mm f/4 Zero-D DSLR is affordable as a manual-focus Nikon F ultra-wide. Condition checks: focus helicoid smoothness, 67mm front element for marks. Manual focus only. Compatible with Nikon F-mount FX and DX bodies.
