Product Details


Fisheye lens of projector is a wide-angle lens that takes in an extremely wide, hemispherical image. The focal lengths of fisheye lenses depend on the film format. Fisheye lenses achieve extremely wide angles of view by forgoing a rectilinear image, opting instead for a special mapping (for example: Equisolid angle), which gives images a characteristic convex appearance. A panorama by rotating lens or stitching images (cylindrical perspective) is not a fisheye photo.
