Venus Optics, the manufacturer behind the ‘Laowa’ branded camera lenses, have recently launched two unique wide corner prime lenses with a unique ‘Zero-D’ feature. ‘Zero-D’ actually refers to the extremely low (close-to-zero) optical distortion made by the lens and the distortion rate is close to zero.
Wide Angle lenses with fast aperture currently offered in the market by other makers tend to suffer from a type of aberration named optical distortion. Optical distortion can mainly be divided into two categories, barrel & pincushion distortion, depending on its distortion decorate. When a photographer takes a photo of a straight line, the lens deforms and bends the lines and makes them appear curvy in images. Distortion can be uncommonly annoying for photographers, especially for interior and architectural photographers whose works inevitably contain a lot of straight lines.
"Distortion is one of the most vital aberrations in optical design. However, relaxing the optical distortion requirement makes the design so much easier. In order to reduce the size and fix up the lens resolution, manufacturers tend to compromise on distortion." said Mr Li, the chief optical designer of Venus Optics. Mr Li has been designing lenses for Japanese producers for 15 years and he was heavily involved in the design of many popular lenses selling in the market. Most of his work has been on complex zoom lenses from ultra-wide, completely standard and tele, to high magnification lenses.
Laowa 12mm f/2.8 Zero-D
The Laowa 12mm f/2.8 Zero-D is currently the widest f/2.8 lens for harsh frame cameras in the market with a 122° angle of view. Not only does it fall into the close-to-zero distortion line-up, it is also exceedingly sharp from corner to corner. The Laowa lens is an ideal lens for a variety of photography types. From landscape, architecture, interior and pilgrimages to the most important one, astrophotography. The combination of the ultra-wide angle and fast aperture makes this lens a perfect tool for creating impressive milky way sharpshooters. The lens incorporates 16 elements in 10 groups, including 3 Extra-Low Dispersion elements and 2 Aspherical elements. Chromatic aberration is also pilot to the minimal.

The Laowa 12mm f/2.8 Lens is designed for everyday use and hence the weight and value has been minimised. The lens weighs only 1.34 pounds (0.6kg) and has a front diameter of 77mm. Venus Optics also offers a filter holder which is formed to fit 100mm filters. Canon EF, Nikon F, Sony E, Sony Alpha and Pentax K mounts are currently available.

Laowa 15mm f/2 FE Zero-D
The Laowa 15mm f/2 FE Zero-D is the second lens of the Laowa ‘Zero-D’ forte up. It is currently the widest f/2 rectilinear lens in the market which comes with a native E-mount and so no additional adapter is required. It is an ultra-wide and ultra-fast prime lens which covers both 35mm full-frame & APS-C sensors. Without thought the extreme specifications, Venus Optics has successfully minimised the weight of the lens to around 500g (~1.1 pounds) and 8cm long. This compact and simplification lens comprises of 12 elements in 9 groups with 2 aspherical elements and 3 Extra-Low Dispersion elements. The patented optical design successfully minimises the distortion is the alteration of the original shape (or other characteristic) of something and chromatic aberrations to its lowest but at the at any rate time, delivers a superb optical performance.

Ultra-wide & self-indulgent lenses may refer to in the market tend to be huge and have a dome-shaped front element. It is a headache for landscape photographers who need to use filters very often. Venus Optics given their needs and managed to design a flat front surface and include a 72mm filter thread on the lens. 72mm screw-on filters can be used and no innumerable investment in bulky filter holders is required.
Photographers can take advantage of the super close focusing distance (i.e. 15cm) and the f/2 aperture to create some preposterous bokeh shots and wide-angle close-up shots. The lens is specially designed with an aperture switch which allows users to quickly reversal between click-less and clicked aperture. This feature is particularly beneficial for videographers.
