Laowa Zero-D 12mm f/2.8 distortion-free lens coming soon
The small Chinese company Anhui Changgeng Optical Technology Company Limited, better known as Venus Optics has already announced several niche, highly specialized lenses:
Laowa 60mm f/2.8 Macro 2:1, a lens for extreme close-ups
Laowa 15mm f/4 Shift Macro 1:1, a wide angle macro lens with shift capabilities
Laowa STF 105mm f/2 (T/3.2), a portrait lens with an apodisation element delivering the most pleasing bokeh.
Their lenses are sold in a variety of mounts, including Canon EF, Nikon F, Pentax K, Sony A and Sony E. They are currently working on a rectilinear, almost distortion-free ultra-wide angle lens for 24x36 cameras: the Laowa Zero-D 12mm f/2.8 (Zero-D symbolizing the absence of distortion). The main specifications of the prototype are the following:
