WIDE OPEN WIDE-ANGLE LENS

A high-aperture wide-angle lens for digital image acquisition, comprising five lens elements, as viewed from the object side, i.e. from the left, a first, negative meniscus lens element, a second, positive lens element, a third, positive lens element, a fourth, negative lens element and a fifth, positive meniscus lens element. A diaphragm is arranged between the second lens element and the third lens element. At least three surfaces upstream of the diaphragm and three surfaces downstream of the diaphragm are embodied as aspherical surface. However, further surfaces can also have an aspherical design. On account of its extremely compact design and its outstanding optical properties, the proposed high-aperture wide-angle lens is suitable as an interchangeable lens for so-called "hybrid cameras".
