67External flash (optional)Flash4Compatible commercially available external flashesWhen selecting an external flash, use products which meet thefollowing basic conditions.(1) Some flashes available on the market operate with a high voltage synchroterminal. If one of these is used, it may damage the camera, and/or thecamera may not function normally. Contact the manufacturer of the flashyou are using concerning the specifications of the flash’s synchroterminal.(2) Some flashes available on the market have the polarity of the synchroterminal reversed. In this case, even if the flash is connected, it will notfire. Contact the manufacturer of the flash for more information.(3) Exposures when using an external flash require that adjustments bemade on the external flash unit. If an external flash is used in the automode, match it with the F value and ISO sensitivity settings on thecamera.(4) Even if the auto F value and ISO sensitivity of the external flash are set tothe same conditions as those on the camera, depending on thephotographic conditions, it is possible that the correct exposure may notbe obtained anyway. In such a case, adjust the auto F value or ISO valueon the external flash unit or calculate the distance in the manual modeand use it that way.(5) Use a flash which is capable of covering an illumination angle for a 38 mmor larger lens when calculated for 35 mm film. However, in close-upphotography with the lens on the wide setting, the bottom of the imagemay not expose correctly. The ideal is to have a wide angle adapter to fiton the flash and spread the illumination angle so it is wider.(6) Use a flash unit with a flash time of 1/200 sec. or less when using the flashat full strength. For devices with a long flash time, a portion of the lightemitted will not contribute to the exposure.(7) If a flash unit or other accessory TTL flash that has additionalcommunications functions other than an Olympus FL seriesexternal flash is used, it may not only fail to function normally, butmay also cause damage to the camera’s circuitry. Do not use such adevice.
