Which might not be that wrong. When zooming the flash one gaines a longer reach fot illumination - that's usually a very good thing. But when you take image indoors, usually there is enough power at the wide flash coverage to illuminate the subject and additionally the light that goes outside of the frame bounces of walls, ceiling etc. and helps to light things in a bit less harsh way. That's mine 0,02PLN to confuse things a bit :-) Maciej
