This lens is totally brand-new optical design different from the Mirrorless version of 14mm f/4 FF RL Zero-D, and is designed for DSLR full-frame cameras. It features 115° angle of view with “Zero-Distortion”, which reduces much time on post-editing. The lens is very tiny and light (Canon EF: 320g/Nikon F: 360g) compared with other DSLR lenses with similar focal length. The 14mm f/4 Canon EF mount is chipped to be automatic in aperture. Users can now control the aperture in-camera and record all the metadata in the EXIF. The lens also has a very short minimum focusing distance, i.e. 14.5cm, capable of creating exaggerated perspective and creamy bokeh. 5 bladed aperture renders stunning 10-point sunstars. The lens is also compatible with 67mm filters.
