摘要
A combined eye- and waist-level real image mode finder is equipped with an objective lens, a first eyepiece, a second eyepiece arranged so that an optical axis is inclined at a predetermined angle with respect to the first eyepiece, and a light beam splitting device disposed between the objective lens and the first and second eyepieces and splitting a light beam coming from the objective lens so that one part of the light beam is incident on the first eyepiece and the other part is incident on the second eyepiece. This finder has therefore important advantages in practical use that even in a status devoid of space to place an eye at an eye point and a case of sudden shutter chance, the field of the picture to be photographed is viewed with a favorable visual field factor, imaging performance and diopter, an image is bright, a twin image is not produced, a field mask is easily set, size is compact, the number of parts is small even in the case of being used as a zoom finder, and parallax is not generated.
