I'm shooting my brothers wedding in May. I'm confused as to what lense to get and use for the wedding. I have a 28-105mm and a 50mm 1.8. I used the 50 mm for a portrait shoot and wasn't very thrilled with it, maybe I'm doing something wrong. It seemed that only the close up pictures turned out good. The 28-105mm is just heavy and sensitive to movement. Any suggestions???
