Laowa 15mm f/2 FE Zero-D (Nikon Z)

Tests show a sharp centre from f/2, with soft outer field and weak corners at f/2 to f/2.8 that become good at f/5.6 to f/8. Distortion is very low for the class, and lateral colour fringing is modest and easy to remove.

The weak points are vignetting of over 3 EV wide open that remains visible at f/8, coma in the corners at f/2 that clears up by f/4, and ghosting with strong light near the frame corners. With no electronic contacts, there is no in-camera correction or EXIF.

Owners like the combination of speed, low distortion and a normal screw-in filter thread, and many use it for astro, real estate and vlogging-style video with the de-clicked aperture. The build and smooth focus ring are well regarded, and Z shooters value it as one of the few fast native ultra-wides for the system.

Common complaints are the heavy vignetting, corner softness wide open for star fields, and the lack of EXIF. With no contacts, Z bodies also need the focal length entered manually for in-body VR.
