A method and apparatus to determine the f that provides optimal image resolution for a predetermined depth-of-field. An approximate and exact method and apparatus are provided to determine the optimal resolution f . The optimal resolution f is a function of the lens focal length, depth-of-field in front of the object, wavelength of light, and distance of the object to the lens center. Once the optimal resolution f is determined, the camera is adjusted to the closest discrete f available. When the approximate field technique is utilized, the camera must be adjusted to the discrete f closest to, but not exceeding, the computed f .
