Auto Aperture (Canon EF); Aperture Coupling (Nikon F)
The 14mm f/4 (Canon EF) is equipped with CPU chips and motors which allows users to adjust the aperture via the body of their cameras. It also stores the metadata in EXIF to improve its convenience. (Nikon F has aperture coupling which records the aperture value in the camera. It is wide open for a brighter preview. The aperture would step down to the set level when you press the shoot button.)
67mm Filter Thread
The design of the 67mm filter thread allows attaching filters directly on the lens. No extra filter holder is needed.
Laowa 14mm f/4 Zero-D DSLR is the first lens in the range getting the focusing scale adjustment system. This new feature allows easy focus calibration against users’ own cameras. The actual infinity point would be right on the infinity mark, making it helpful in shooting in the field, especially in astrophotography.
