Fish eye lenses are the most unique and most popular type of lens for artistic photography purposes. This lens is specifically designed to produce extreme distortion in photos. The resulting distortions include oval, flat, or curved.
In fact, a fish eye lens is a wide angle lens with a diameter of 8-16 mm. The viewing angle of this lens reaches 180°. A lens with a size of 8-10 mm will produce oval distortion, while a size of 15-16 mm will produce a photo that is generally rectangular, but still with very excessive distortion. Distortion in this type of lens is a work of art in itself. But unfortunately, fish eye lenses are lenses with quite expensive prices on the market.
