[. . . ] When the WC-E80 is used with the COOLPIX 5400, loss of resolution will occur at the margins of the frame in photographs taken at maximum aperture. Photographs can be taken using the converter lens even if Wide Adapter is not selected. [. . . ] This converter lens is intended for use with the Nikon COOLPIX 5700 and 5400. Mounting the converter lens increases the total weight of your camera. Do not pick the camera up by the converter lens alone when the converter is attached, as this may damage the equipment. "Ghosting" may occur when a very bright light source, such as the sun, is framed in the photograph or is just outside the frame. Some distortion may occur in the periphery of photographs taken with the converter lens. When focus mode is set to infinity with the converter lens attached, the actual focus distance will differ from the distance selected due to optical characteristics of the converter. It is recommended that you check the image in the monitor or viewfinder or use autofocus. Replace the front and rear lens caps when the converter lens is not in use. Note that it is sometimes difficult to remove the front cap when the ambient temperature is low. Be careful not to scratch the lens, which is particularly susceptible to damage due to its large diameter. To remove fingerprints or other stains, wipe the lens gently with a soft, clean, cotton cloth dampened lightly with pure ethanol. Move the cloth in an even spiral from the center outward, being sure to clean all parts of the lens. Taking photographs with the WC-E80 Taking photographs with the Camera in Wide Adapter mode Selecting Wide Adapter from the LENS submenu in the SHOOTING menu automatically changes camera settings to create photographs that make the best use of the converter lens. Use the multi selector to select Wide Adapter from the LENS sub-menu in the SHOOTING menu. [. . . ] Avec ce mode, le CoolPix 5700 peut effectuer des prises de vues à une distance allant de 23 cm environ à l'infini et le CoolPix 5400 d'une distance proche de zéro à l'infini. Lorsque le mode de mise au point est réglé sur l`infini quand le convertisseur est monté, la distance focale réelle différera de la distance sélectionnée en raison des caractéristiques optiques du convertisseur.
