The SF 26 unites stylish design with the greatest possible unobtrusiveness and discretion. At the same time, the distance between the flash reflector and the camera lens is large enough to drastically reduce the red-eye effect when photographing people or animals. The unit has a maximum guide number of 24 at ISO 100 and 26 when its telephoto diffuser is attached. The angle of illumination corresponds to a range of focal lengths from 35 to 85mm and can be expanded to 26mm for wide-angle lenses and 135mm for telephoto lenses with the two diffusers provided.
