ENG-5 Mounting and Detaching the Lens See your camera’s instructions for details on mounting and detaching the lens. .. 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 as shown in the diagram, and turn clockwise. To remove it, reverse the order. 2 Setting the Focus Mode To shoot in autofocus (AF) mode, set the focus mode switch to AF. To use only manual focusing (MF), set the focus mode switch to MF, and focus by turning the focusing ring. After autofocusing in ONE SHOT AF mode, focus manually by pressing the shutter button halfway and turning the focusing ring. .. Quickly rotating the focusing ring may result in delayed focus. .. Manual focus adjustments are not possible when the camera is OFF. ENG-6 ENG-7 3 Hood (sold separately) 4 Zooming To zoom, turn the lens’ zoom ring. ..Be sure to finish zooming before focusing. Zooming after focusing can affect the focus. ..Blurring may temporarily occur if the zoom ring is quickly rotated. ..Zooming when the camera is OFF will result in delayed focus. ..Zooming during still image exposure will result in delayed focus. This causes any streaks of light that are captured during exposure to be blurred. The EW-73B hood cuts out unwanted light and protects the front of the lens from rain, snow, and dust. To attach the hood, align the hood’s attachment position mark with the red dot on the front of the lens, then turn the hood as shown by the arrow until the lens’ red dot is aligned with the hood’s stop position mark. The hood can be reverse-mounted on the lens for storage. .. If the hood is not attached properly, vignetting (darkening of the perimeter of the picture) may occur. ..When attaching or detaching the hood, grasp the base of the hood to turn it. To prevent deformation, do not grasp the rim of the hood to turn it. Fixing the Zoom Ring 5 The zoom ring can be fixed to keep the lens at the shortest point.
