The Chinese manufacturer Venus Optics has specialized especially in the production of (very) wide-angle lenses. Now the Laowa 14mm f/4 Zero-D for DSLR appears, a manual full-frame fixed focal length that was already launched last year 
for mirrorless full-frame cameras.

However, this new ultra-wide-angle lens with Canon EF or Nikon F bayonet has been redesigned due to the larger flange focal length and features a different optical construction (13 elements in 8 groups including 2x ED and 2x aspherical glass) and is a bit longer again at 75mm (EF) and 73mm (F) and also heavier. It weighs 320g (EF) and 360g (F).
The minimum focusing distance is only 14.5cm. The angle of view is 115°, similar to the DSLM variant, and the image is again rectilinear, i.e. the wide-angle typical image curvature is corrected ("Zero-D" as in distortion). The aperture is again composed of 5 blades. The version for Canon EF supports metadata and an aperture setting via the camera controls.
