A viewing apparatus includes a viewing optical system having a positive objective optical system and a positive eyepiece optical system, an image of an object formed through the positive objective optical system being viewed through the positive eyepiece optical system; a photographing optical system, provided independently from the viewing optical system, for photographing the object image viewed through the positive eyepiece optical system; a first focusing mechanism for changing an image focal point of the object image formed through the positive objective optical system of the viewing optical system; a second focusing mechanism for changing an image focal point of an object image formed through the photographing optical system; an interconnection mechanism which interconnects the first focusing mechanism with the second focusing mechanism; and a release mechanism for releasing the interconnection mechanism so that the first focusing mechanism and the second focusing mechanism can operate independently of each other.
