The Laowa 12mm f2.8 Zero-D is a seriously wide-angle prime lens that features a rectilinear optical design. It has been specifically created to limit distortion for accurate and clear portrayals of landscapes and architectural subjects. This full-frame compatible lens is built up of 16 elements in 10 groups with a 7 blade aperture - to include 2 aspherical and 3 extra-low dispersion elements. These specific elements control both spherical and chromatic aberrations for improved sharpness and reduced colour fringing. This 12mm lens features an efficient manual focus design with a floating optical system - reliably accurate rendering throughout full focus range (18cm - infinity). It's also highly durable, with a Frog Eye Coating to repel dust and moisture from the front of the lens. A built-in petal-shaped lens hood further reduces flare and ghosting when dealing with intense lighting conditions. This lens is best suited for astro, landscape and architectural photography.
