a Safety Precautions a Safety Precautions • Do not look at the sun or a bright light source through the lens or camera. Doing so could result in loss of vision. Looking at the sun directly through the lens is especially hazardous. • Whether it is attached to the camera or not, do not leave the lens under the sun without the lens cap attached. This is to prevent the lens from concentrating the sun’s rays, which could cause a fire.

1. Mounting and Detaching the Lens 2. Setting the Focus Mode 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 electrical 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.

3. Switching the Focusing Distance Range 4. Hood Y P O You can set the focusing distance range to 0.31 m/1.0 ft. to infinity or 0.48 m/1.6 ft. to infinity. By setting the suitable focusing distance range, the actual autofocusing time can be shorter. C If you autofocus outside the set focusing distance range, the lens may stop focusing at the start of the focusing range; however, this is not a malfunction. Press the shutter release button halfway again.

5. Picture Taking Normal Photography The lens can be used as a medium-telephoto lens for normal photography such as portraits. Closeup Photography Close-up photos up to 1x (life-size) magnification are possible. The minimum focusing distance of 31 cm is the distance from the subject to the focal plane. The working distance from the front of the lens to the subject is about 15 cm. When focusing, you can give priority to framing or to magnification. [Framing Priority] C 1.

6. About Exposure Setting the Exposure When taking photographs using TTL metering, no exposure compensation is necessary to meter the light coming through the lens. With TTL metering, AE (autoexposure) is possible at all focusing distances. Just set the desired picture-taking mode, then check the shutter speed and aperture before taking the picture. Magnification and Effective fnumber C The aperture displayed by the camera assumes that the focus is set to infinity.
