Laowa's ultra-wide rectilinear for APS-C — 13.5mm equivalent with near-zero distortion and compact design.
The Laowa 9mm f/2.8 Zero-D (2017) delivers a 13.5mm equivalent ultra-wide rectilinear image on APS-C — one of the widest non-fisheye primes for crop sensors. The Zero-D designation indicates near-zero distortion — straight lines stay straight.
Sharp across the frame when stopped down. Near-zero distortion — impressive for this extreme width. f/2.8 decent for ultra-wide. Manual focus with hard infinity stop. Compact at 215g.
Fujifilm X mount. No electronic contacts — no EXIF. Manual focus only. 49mm filter thread. 215g. 12cm close focus. Also available in Sony E, Canon EF-M, and MFT mounts.
Good used availability. Check focus ring damping. The lack of electronic contacts means no EXIF data — a workflow inconvenience. Outstanding for real estate interiors and landscape at this extreme width.
