Laowa's ultra-wide 12mm equiv rectilinear prime for MFT — f/2 with zero distortion in a tiny package.
The Laowa 6mm f/2 Zero-D is a manual-focus ultra-wide prime for Micro Four Thirds, providing a 12mm full-frame equivalent field of view with near-zero barrel distortion — the Zero-D designation. At 188g and 58mm filter thread it is compact. Electronic aperture contacts are present for body control of aperture, but there is no autofocus motor. 5 aperture blades. MFD of 9cm.
The optical design uses 13 elements in 9 groups with 2 aspherical elements. Five aperture blades. The 58mm filter thread. At 188g the lens is very lightweight. Minimum focus distance of 0.09m. Electronic aperture contacts — aperture set via camera body. No autofocus. f/2 maximum aperture. MFT image circle. 121.9° field of view on Micro Four Thirds (12mm full-frame equivalent).
The Zero-D designation indicates near-rectilinear distortion correction at an extreme wide angle: conventional ultra-wide lenses at this field of view exhibit significant barrel distortion; the Laowa 6mm reduces this to near-negligible levels for architecture, interiors, and documentary photography where straight-line rendering is important. The 0.09m MFD enables extreme close-wide environmental compositions. At f/2, low-light and astrophotography on MFT are practical.
On the used market the Laowa 6mm f/2 Zero-D MFT is available at affordable manual-focus ultra-wide prime pricing. Condition checks: electronic aperture contacts function, manual focus ring smoothness, 58mm front element for marks. No autofocus. Compatible with all Micro Four Thirds bodies from Panasonic, Olympus, and OM System.
