Exceptionally wide, the Laowa 17mm f/4 GFX Zero-D from Venus Optics is an impressive ultra-wide prime designed for FUJIFILM G-mount mirrorless medium format cameras. With a broad 113° angle of view, this lens is well-suited to a range of subjects, including architecture, interiors, landscapes, and astrophotography. The optical design incorporates a series of extra-low dispersion and aspherical elements, which correct a variety of aberrations in order to produce high sharpness, clarity, and color accuracy. As part of the Zero-D series, this lens also offers notable distortion control for accurate subject portrayal. A Frog Eye coating has been applied to the front element, as well, which protects the lens from dust and moisture. Additionally, its manual focus design permits working with subjects as close as 7.9" away and a five-blade diaphragm contributes to producing 10-point sun stars.
