PROBLEM TO BE SOLVED: To provide an optical equipment capable of correcting the divergence of focus even in the case of environmental change and obtaining excellent optical performance. SOLUTION: This optical equipment for forming a subject image on an image- formation surface by an optical system 1 including moving lens groups 102 and 104 is provided with lens driving means 5 and 6 driving the lens groups 102 and 104, a control means 13 controlling the driving means 5 and 6, a storage means 14 storing control information for driving the lens groups 102 and 104, and a detection means detecting temperature information or/and humidity information concerning the optical system 1. The control information has specified data, and the control means 13 controls the driving means 5 and 6 by using the control information and the specified data so as to correct the fluctuation of the position of the image-formation surface of the optical system 1 associated with temperature change or/and humidity change. |
