Hey guys, i'm using a d70 with a SB-600 flash unit..for some reason, i can't seem to get it to do the auto zoom thing whenever i zoom in and out with my lens..it works sometimes..as in..it switches to the auto zoom on it's own..but i can never seem to select it when i want to..plus ttl always seems to produce over exposed pics while the manual one never seems to work out well for me.....anyone able to help?
