PROBLEM TO BE SOLVED: To provide a camera, with which the increase of a wage and the occurrence frequency of defective are suppressed and whose cost is low by enhancing the flow of camera manufacturing work, for improving the yield of a lens and also improving yield as a product. SOLUTION: In the manufacturing process of the camera, having a first process to check and evaluate the characteristics of a camera lens and a second process to detect a numerical data, with respect to focus under a specified first condition to decide a reference position at the focusing time of the lens; an adjustment system to perform the adjustment method of the camera by which the numerical data is detected by adding a prescribed second conditions, in addition to a first condition at the second process, in accordance with the evaluated result of the lens at the first process is proposed. The characteristic evaluated at the first process is at least either one of the focal position direction of the lens in a prescribed chart direction, a change in the focal position of the lens due to a light source color and the change in the focal position of the lens due to its spatial frequency characteristic.
