Sell optical proector fisheye lens

Description

Fisheye lens 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.
