Abstract
A rangefinder optical system with a first optical system, a field frame optical system, and a second optical system, further including a field frame reflection member; a second optical system reflection member, and an optical-path merging member of the second optical system. A second image by the second optical system is formed on the side of the second optical system reflection member with respect to the optical-path merging member of the second optical system, i.e., when viewed from the first optical system, the second image is formed at the position substantially optical-equivalent to the position of the field frame member.
