The Laowa 9mm f/2.8 Zero-D from Venus Optics is a Sony E-mount lens offering a 13.5mm equivalent focal length, combining an ultra-wide-angle field of view with a particularly compact design. As a Zero-D lens, the 9mm f/2.8's optical design is specifically engineered to minimize distortion for clear, sharp images of landscapes and architectural subjects. The optical construction also incorporates two 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 also been applied to repel dust and moisture from the front element of the lens, benefiting working in challenging environmental conditions. Its sleek, lightweight design is compatible with mirrorless bodies and is ideal for everyday shooting as well as on-kilometre use. Additionally, a petal-shaped lens hood is incorporated into the lens design to reduce flare and ghosting when working in strong lighting conditions.
