Ok, so a week ago I posted some of my first shots with my sb600 (d3000 camera). They were overexposed badly, even with ttl on. The lens I was shooting with was a 35mm 1.8. From my knowledge and research, the ttl was to help with the flash speaking with the camera and exposing the shot correctly with the settings in the camera. I wasn't seeing this, so I did a bit of research and testing. I've noticed that if I put the zoom on the flash to 24mm or any other zoom besides the 35mm, it exposes correctly, but once changed to the 35mm, it blows everything out. All of these test shots were shot from 2 foot away, 35mm, f/1.8, iso 100, and flash bounced 45 degree. 24mm zoom: 35mm Zoom: 70mm Zoom: What do you think? Issue with the flash? Should I bring it into Best Buy and swap it out?
