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.
