Cautions

• If the external flash is on, it will fire with every shot regardless to the flash mode selected with the camera. Turn the flash unit off to shoot without the flash.

•Optional flash units are in principle for use at ranges that exceed the range of the built-in flash. Using an optional flash unit at shorter ranges may result in overexposure.
