Using Conversion Lenses (Sold Separately) Conversion Lens Adapter LA-DC52E and Lens Hood LH-DC20 are included in the separately sold Lens Adapter/Hood Kit LAH-DC10. The camera supports use of the separately sold Wide Converter WC-DC52A and Tele-converter TCDC52B. In order to attach any of these lenses, you also need to use the separately sold Conversion Lens Adapter LA-DC52E (included with LAH-DC10). When shooting in backlit conditions without the flash and at the wide angle end, the use of the lens hood is recommended to prevent external light from entering the lens. Warning z When attaching the wide converter or teleconverter, be sure to screw it on securely. If they come loose, they may fall from the lens adapter, posing risk of injury from shattered glass. z Never look into the sun or into strong light through the wide converter or tele-converter as this can result in blindness or impairment of vision. zIf you use the built-in flash when shooting with the wide converter, the outer area of the recorded image (especially the bottom part of the image) will come out relatively dark. zWhen using the wide converter, please set the camera to the wide angle end. zWhen using the tele-converter, please set the focal length to the telephoto end. At other zoom settings, the image will appear as if its corners have been cut off.
