The Laowa 15mm f/2 Zero-D is one of the brightest and least distorted ultra-wide-angle lenses on the market for Nikon Z full-frame cameras, with a maximum aperture of f/2.0. The optical construction of this 580 g lightweight and nearly 9 cm long lens consists of 12 elements in 9 groups, including 2 aspherical elements and 3 extra-low dispersion elements. The patented optical design successfully minimizes distortion and chromatic aberration while delivering excellent optical performance right into the corners of the image. Ultra-wide and bright lenses available on the market are typically very large and often feature a dome-shaped front lens, which poses a particular challenge for landscape photographers who frequently use filters. Venus Optics has addressed this need by developing the lens with a flat front lens that allows for a 72 mm filter thread, enabling the use of standard 72 mm screw-in filters. Additionally, this lens offers photographers the ability to capture sharp images of nearby objects thanks to its super-short minimum focusing distance of 15 cm, and the large f/2.0 aperture allows for wide-angle shots with beautiful bokeh.
