[. . . ] Observe the following precautions when handling the camera and lens â· Keep the camera and lens unit dry. When shooting with back-lighting, do not point the lens at the sun or allow sunlight to pass directly down the lens as this may cause the camera to overheat and possibly cause a fire. [. . . ] If your camera has a depth of field preview (stop-down) button or lever, depth of field can be observed while looking through the camera viewfinder. Due to the optical characteristics of this lens, as the lens is focused closer, the focal length slightly decreases. Autofocus is provided while lightly pressing the shutter release button. Be careful not to touch the focus ring 5 when it is turning during autofocus operation. Shooting is possible when camera's focus mode is set to either AF or M. Camera's focus mode AF-A/AF-S/AF-C M -- A Autofocus Manual focus (Focus assist is available) M For more details on camera's focus mode, refer to your camera user's manual. Note: Be sure to set the switch # so that the indicator aligns with [ON] precisely. 2 Vibration is reduced when the shutter release button is lightly pressed. Because vibration is reduced in the viewfinder, auto/manual focusing and exact framing of the subject are made easier. Wait until the image in the viewfinder stops vibrating before fully depressing the shutter release button after you have lightly pressed the shutter release button. â· If you move the camera in a wide arc when panning, vibration in the direction of that movement is not affected. For example, if you pan the camera horizontally, only vibration in the vertical direction is reduced, making smooth pans much easier. â· Due to the characteristics of the vibration reduction mechanism, the image in the viewfinder may become blurred after releasing the shutter. â· Do not turn the camera power OFF or remove the lens from the camera while the vibration reduction mode is in operation. [. . . ] â· When the lens will not be used for a long time, store it in a cool, dry place to prevent mold. Do not get water on the lens or drop it in water as this will cause it to rust and malfunction. [. . . ]
