With the dedicated SF-24D Flash Unit, the camera fully automatically controls the amount of light emitted by the flash unit, just as it does with the built-in flash. Precisely exposed flash pictures with balanced illumination can be taken by means of the guide number control. The 'SLOW' mode, which can also be synchronized to the second shutter, expands the creative possibilities. Even with fill -in flash, the natural light mood is preserved by means of longer shutter speed. Furthermore, the external flash shoe provides a connection to SCA flash units.
