A truly wide-angle prime featuring a rectilinear optical design, the Sony E-mount Laowa 12mm f/2.8 Zero-D from Venus Optics 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. Benefitting the optical attributes, this lens also features a precise manual focus design along with a floating optical system to maintain accurate rendering throughout the focus range, from 7.09" to infinity. Additionally, a petal-shaped lens hood is also incorporated into the lens' design to reduce flare and ghosting when working in strong lighting conditions.
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 Micro Four Third M4/3 mount lens offering a 13.5mm equivalent focal length.
This lens is currently the widest rectilinear lens available for Micro Four Thirds cameras. It gives a field of view equivalent to a 15 mm lens on 35 mm sensors. This allows MFT users to enjoy an impressive 110° ultra wide angle of view for a broad range of shooting. The wide angle of view and ultra-fast aperture are extremely valuable for astro-photography. This lens is super compact and lightweight for casual on-the-go use. A ultra-light version is also available for aerial photography usage.
