1. Mounting and Detaching the Lens 2. Focusing See your camera's instructions for details on mounting and detaching the lens. ● When mounting or detaching the lens, always ensure that the tilt and shift scales are set to the "0" position. ● After detaching the lens, place the lens with the rear end up to prevent the lens surface and contacts from getting scratched. ● If the contacts get soiled, scratched, or have fingerprints on them, corrosion or faulty connections can result. The camera and lens may not operate properly. ● If the contacts get soiled or have fingerprints on them, clean them with a soft cloth. ● If you remove the lens, cover it with the dust cap. To attach it properly, align the lens mount index and the index of the dust cap, and turn clockwise. To remove it, reverse the order. Focus a TS-E lens by turning the focusing ring. (Shots cannot be taken using the auto focus.) ● After using tilt or shift, readjust the focus. ● The distance scale is only valid when the tilt scale is set to the "0" position. ENG-5
