Venus Optics has announced a new Laowa 14mm f/4 Zero-D (zero distortion) wide-angle manual focus prime lens for Canon EF and Nikon F mount.
The company says this lens is specifically designed for these systems that it uses a completely different optical design and is not just a rehoused version of the mirrorless ones launched last fall.

The lens is constructed of 13 elements in 10 groups and includes two extra-low dispersion elements and two aspherical elements, the latter added to eliminate color fringing and distortion. Like other Laowa ‘Zero-D’ lenses, the lens features near-zero distortion, despite its wide angle of view. The lens includes a CPU chip and motor in the Canon EF version, which allows photographers to adjust the aperture via the camera body and will also store EXIF data in photos. The Nikon version has aperture coupling which the company says “provides a clear preview before it is stepped down to the set value.” It’s also the first lens to get what Venus Optics calls a focusing scale adjustment system, this feature allows photographers an easy focus to calibrate it against the users’ specific camera, allowing the infinity point to actually be exactly on the infinity mark. Below is the company’s tutorial on how to calibrate the lens:
