Specification :
Presenting an immensely wide field of view within a truly compact package, the Laowa 4mm f/2.8 Fisheye provides a huge 210° angle of view for Micro Four Thirds mirrorless cameras. As a circular fisheye, this lens is characterized by its noticeable distortion and bulb-like visual appearance. The greater-than-180° angle of view also enables making full 360° stitched panoramas with just two shots. The lens also sports a bright f/2.8 design for working in available lighting conditions and its manual focus design permits working with subjects as close as 3.1" away for true close-up shooting. Additionally, the fisheye design retains almost full depth of field when stopped down to f/5.6 for consistent and even sharpness.
