World's widest full-frame rectilinear lens at 9mm — no fisheye distortion — with near-zero distortion design.
The Laowa 9mm f/5.6 FF RL is the world's widest non-fisheye lens for full-frame cameras, covering a 113° field of view while keeping straight lines straight. This is a remarkable optical achievement — most lenses this wide produce fisheye distortion.
Remarkably sharp considering the extreme coverage. Near-zero distortion — straight lines remain straight. Compact for the coverage. Manual focus with hard infinity stop. Built-in rear filter frame for gel filters. f/5.6 is slow.
Sony FE mount. No front filter thread — built-in filter system at rear. Manual focus only. No electronic contacts on some versions. Compact despite the extreme wide-angle. Also available in Nikon Z and L-Mount.
Limited used availability. Check the rear filter frame functions. Test at f/8 for best sharpness. This is a specialist lens for architecture, real estate interiors, and landscape — the 9mm perspective takes practice to use effectively.
