The Laowa 17mm f/4 GFX Zero-D is an ultra-wide prime lens designed for Fujifilm G-mount medium-format mirrorless cameras. It provides a 113° angle of view, equivalent to approximately 13mm on a 35mm-format camera, making it suitable for expansive landscapes, architecture, interiors, and astrophotography.

Its Zero-D optical design minimizes distortion, while two aspherical and three extra-low dispersion elements help control optical aberrations. Manual focus supports close focusing to 20cm, and the five-blade aperture creates 10-point sun stars
