VIBRATION PROOF LENS ATTACHMENT

摘要

PROBLEM TO BE SOLVED: To increase the degree of freedom of constitution, to arbitrarily set the magnification and to improve the optical performance by including a compensating lens group attachable/detachable and movable in the direction orthogonal to the optical axis and providing a vibration proof lens system including a specified number of positive lenses and negative lenses between a photograhping lens system and a camera body. SOLUTION: A vibration proof attachment 10 is provided with a lens mount MTM for mounting a photographing lens system 20 in the front end part and a body mount MTA for connecting a camera body 30 in the rear end part. A vibration proof lens system 13 composed of a compensating lens group 11 movable in the direction orthogonal to the optical axis and a fixed lens group 12 is arranged on the rear position of an image forming position FM by a master lens 20 in the vibration proof attachment 10. The vibration proof lens system 13 inverts the image by the master lens 20 formed on the image forming position FM and re-formes it on the image forming surface 31 of the camera body 30. The vibration proof lens system 13 includes more than six sheets of positive lenses and more than two sheets of negative lenses.
