Pairing an ultra wide-angle field of view with an especially compact design, this Laowa 9mm f/2.8 Zero-D from Venus Optics is a  lens offering a 13.5mm equivalent focal length. As a Zero-D lens, this 9mm f/2.8's optical design is specifically meant to limit distortion for clear and accurate portrayals of landscapes and architectural subjects. The optical construction also incorporates a pair of aspherical elements and three extra-low dispersion elements to control both spherical and chromatic aberrations for improved sharpness and reduced color fringing. A Frog Eye Coating has been applied, too, to repel dust and moisture from the front element of the lens to benefit working in trying environmental conditions. Its sleek and lightweight design is well-matched to mirrorless bodies and is ideal for everyday shooting as well as use on gimbals. Additionally, a petal-shaped lens hood is also incorporated into the lens' design to reduce flare and ghosting when working in strong lighting conditions.
