Note When a recommended external flash is attached, the built-in flash does not fire. Caution • When using an external flash only or if the internal flash does not pop up normally when an external flash is connected, set the internal flash to [Flash Off]. • Irrespective of flash setting, a flash ON signal is output to the X contact of the hot shoe. To stop an external flash, use a switch on the flash. • Exposure may not be appropriate even when the f-number and ISO sensitivity of the external flash are the same as those of the camera. If so, change the f-number and ISO sensitivity of the flash. • As the flash ON signal, the camera outputs a positive pulse to the X pulse contact. • A flash on the market rarely have an X contact of the opposite polarity. This kind of flash may not only not work but also cause a problem to the camera. For the terminal specifications, contact the manufacturer of the external flash. • Use an external flash of a lighting angle covering the angle of view of the shooting lens. • Use an external flash basically at a distance where the internal flash is not adequate (long distance). Shooting at a short distance may end in over-exposure. • Do not use an external flash having a special signal pin. Using such a flash may cause inappropriate exposure or damage of the camera circuit. 46
