I shoot most of my Reportedge™ from the back of the mobile glamour unit using massive telephoto lenses. A 2000mm with 2 times converter will usually suffice. I find that most Churches handily reserve a space for me to park right outside the gate and I get Muktar to open up both doors giving me the perfect view right down the aisle. The advantages of shooting from the car should be obvious: you can listen to the football rather than the hymns; you can smoke: you don't have to talk to anybody. The only real disadvantage is that you can sometimes end up shooting the wrong wedding but that was Muktar's fault. He was driving that particular day, because I was too drunk.
When you get to the reception you should switch to a 8mm Fisheyes lens. Wedding receptions are not nearly as dangerous as large dawn beach landings and the Fisheyes will allow you to keep close to the booze waiters. Capa would have done it this way - he loved a bit of booze.
