(54) LENS SYSTEM


(57) A plurality of interchangeable lenses is provided, any one of which can be attached to a camera housing for capturing an image. Each lens has a focal length that differs from the focal length of the other lens or each other lens. Each lens has a focus scale a focus index mark, so that the lens can be focused at a desired focus distance by relative movement of the focus scale and the focus index mark. The focus scale is divided into at least two sub-ranges. One of the sub-ranges is a principal sub-range that extends from a focus distance of infinity to a focus distance of 2m (six feet), wherein the relative position of the focus scale and the focus index mark that is required to focus the lens at any focus distance within the principal subrange is the same for at least two lenses.
