Abstract

PURPOSE: To make possible observation and photographing of the subject without depending upon intricate construction by mounting a high magnification finder to the telephoto lens for photographing and moving the front group lens of the telephoto lens and the objective lens of the finder simultaneously by the same quantity.
CONSTITUTION: The front group lens 2 of a telephoto lens 1 for photographing is mounted to a moving lens-barrel 4 and the rear group lens 3 is mounted to the stationary lens-barrel 5 mounted removable to the lens mount 6 of the camera. The lens-barrel 4 is inserted to the lens-barrel 5 and the guide groove 7 provided to the lens-barrel 4 is moved straight forward or barkward by the guide pin 8 screwed to the lens-barrel 4. The objective lens 9 of the finder 10 has the same focal length as that of the front group lens 2 of the lens 1 for photographing and forms the erecting image of the far object on the finder frame 12 through an erecting prism 11. The objective lens 9 is mounted to the moving lens-barrel 13 of the finder 10 and this lens-barrel 13 is integrally constituted with the moving lens-barrel 4 by a connecting part 14 and is moved cooperatively with the front group lens 2. The stationary lens-barrel 15 of the finder 10 opposing to the moving lens- barrel 13 is constituted integrally with the foregoing stationary lens-barrel 5 by a connecting part 16.
