PROBLEM TO BE SOLVED: To solve the following problems; regarding a conventional lens apparatus, the whole lens apparatus must be disassembled in order to adjust an image blurring correcting apparatus or in order to replace components when such a situation occurs that thrust of prescribed level to move a correcting lens is not obtained or that a moving distance is too short to obtain a prescribed stroke, then, it is difficult to carry out the adjusting work, consequently, the yield of products is reduced. SOLUTION: The lens apparatus includes; a lens system 2 where a plurality of lenses are arranged on the optical axis while aligning the optical axes L with each other; a lens barrel 3 which fixedly or movably supports the plurality of lenses; the correcting lens 15 which can move in a direction orthogonal to the optical axis of the lens system; and a moving mechanism of moving the correcting lens in a direction orthogonal to the optical axis. Blurring of an image obtained through the lens system can be corrected by moving the correcting lens 15 in the orthogonal direction in accordance with the shake of the lens barrel 3. An image blurring correcting unit 5 is formed by unitizing the correcting lens 15 and the correcting lens moving mechanism, and a unit storing part 48 to which the image blurring correcting unit 5 can be freely attachably/detachably loaded is provided on the lens barrel 3.
