Fish eye lenses open unusual perspectives. With extraordinary optical characteristics this lens substantially extends your creative possibilities. It zooms steplessly through a picture angle of 180 to 100 degrees, which permits a new level of dramatic imaging nuances. With the special optical design you can realize striking macro photographs from a distance of only 2.5cm. Employing ED (Extra-low Dispersion) glass, this lens effectively overcomes chromatic aberation throughout the image - an effect particularly noticable with enlargements. What's more, the front lens element is dirt and water repellent with the unique PENTAX SP protective coating.
