USING YOUR LENS SAFETY 1 Although we have carefully designed these lenses for safe operation, please pay special attention to items marked with the following symbols when using this product. WARNING This symbol indicates precautions that if not followed, could result in serious injury to the user. This symbol indicates precautions that if not followed, could result in minor or medium injury to the user or damage to the equipment. CAUTION 2 WARNING · Never look at the sun through the lens or camera. [. . . ] The aperture is controlled at the A [Auto] setting. Therefore, the lens is not compatible with cameras and accessories which are not compatible with the A setting. 9 A zoom lens has two rings: The focusing ring at the front of the lens and the zoom ring behind it. Turn the zoom ring to obtain the desired angle of view (focal distance). * Whenever you turn the zoom ring to change the angle of view (focal distance), the focus may also change slightly. First turn the zoom ring, then focus. About the zoom ring Turning the zoom ring to the right gets a [Telephoto] effect, making the subject look larger. Turning it to the left gets a [Wide angle] effect, covering a wider area. 10 Changing the Lens 1. Align the mount index red dots on the camera body and lens and attach the lens. Turn the lens clockwise until it locks in place. 2. To detach the lens, hold down the camera's lens unlock button, then turn the lens counterclockwise. * When attaching a lens, do not press the camera's lens unlock button. Doing so causes improper lens attachment. * After attaching a lens, turn the lens counterclockwise slightly to make sure the lens is locked in place. Finger Point on Limited Lenses Lens Cap 11 You can easily attach a Limited lens by aligning the finger point on the lens with the camera's lens unlock button. For example, with a 28-105mm zoom lens set to 105mm, set the f/8 aperture by aligning the aperture ring's f/8 to the [Long focal length aperture index] mark on the left of the white index. * When setting the aperture manually at a middle focal length, use the aperture index for the short and long focal lengths as a reference. 17 Apertures and Click Stops Certain lenses have a white dot next to the maximum aperture. The white dot indicates a difference of one aperture stop. For example, as shown on the right, the white dot next to f/2 indicates f/2. 8. If there is no white dot for a click stop between the f/numbers, the click stop indicates the respective f/number shown below. Also, certain lenses have no intermediate click stop at both ends of the aperture scale due to a lack of space. Do not set the aperture ring to a position where there is no click stop. 1. 4 1. 2 1. 7 2 2. 4 2. 8 3. 4 4 4. 8 5. 6 6. 7 8 9. 5 11 13. 5 16 19 22 26 32 38 45 18 Using the Infrared Index 15 8 ft 10 3 2 m 22 16 8 50 22 16 8 15 8 ft 10 3 2 1 m 50 16 11 8 5. 6 4 2. 8 2 1. 4 A 22 16 11 8 5. 6 4 2. 8 2 1. 4 A 22 If you use infrared film with an R2 or O2 filter, the point of focus differs from normal shooting (with visible light). This means the point of focus must be corrected. * Infrared film cannot be used with camthe MZ-S, MZ-60, and eras since these cameras use infrared light to detect film transport operations. When the subject is in focus in the viewfinder, note the point of focus on the distance scale (shown in the left illustration). Then turn the focusing ring so the respective point of focus on the distance scale is aligned with the infrared index mark, as shown in the right illustration. * Before turning the focusing ring, set the focus mode to manual focus. * To determine the proper exposure, refer to the film's instruction manual. 19 Zoom Lens Infrared Index With a zoom lens, the focusing correction amount for infrared film shooting varies depending on the focal length.
