The very high contrast, the perfect reproduction of the finest image details and the virtually complete insensitivity to flare even at maximum aperture are characteristic features of this versatile ultra-wide-angle lens. It is a brilliant performer on photojournalism assignments and fashion shoots, for architectural photography and for achieving dramatic landscape perspectives, and its highly compact size makes it especially practical and user-friendly. Its retrofocus design provides impressive results close up too. The built-in filter wheel offers 4 filter choices.
