摘要： A variable magnification finder has an objective lens group having an overall positive power. A first lens group and a second lens group each have a negative refractive power; a third lens group and a fourth lens group each have a positive refractive power; and an eyepiece lens group has a positive power. The second and third lens groups move to zooming from the wide angle position to the telephoto position, and compensate the change of an aberration resulting from such movement of the second and third lens groups.

摘要： A real image finder includes an objective lens group, an inverting group and an eyepiece lens group. The objective lens group includes a first lens unit of a negative refractive power, a second lens unit of a positive refractive power, a third lens unit of a positive refractive power, and a first prism of a positive refractive power, where an exit surface of the first prism is convex toward an image. The objective lens group forms an inverted image. The inverting group forms an erect image by inverting the image formed through the objective lens group. The eyepiece lens group magnifies the erect image formed by the inverting group.
