I have a new Digital Rebel with a ef 17-40 L series lens and a 550ex external flash. I have had this for about two weeks and the pictures I have been taking inside my house are horrible. I have had it on auto modes and the picture quality is no where near my previos Canon G2. The pictures are very dark. Its like my flash unit is not sync-ed up with the camera. Can anyone please help me out with this.
Thank You!!!
