The Leica SF 24D electronic flash unit is designed to be compact and also to provide the maximum distance between the flash reflector and the camera lens, which minimises the risk of red eye when photographing people and animals. In automatic mode, six automatic flash apertures 2.0/2.8/4.0/5.6/8/11 are available. An override switch allows the exposure to be varied by plus/minus three stops. All settings and other information are legibly displayed on the Leica SF 24D's illuminated LCD. These include an exposure confirmation indication and flash ready light.
