My friend wants me to shoot his wedding. Yikes. The ultimate faux pas.
I make money taking pictures of kids, events, and a bit of candid work, but I am terrified of the group shots, mainly because of lighting. I don't need any advice on the rest of the shoot. I have plenty of experience shooting candid event work with any lighting.
I can assume that I will be in a church with groups up to 15 and as small as 2. I am shooting with a 5D and I have an 85 1.8, 50 1.4, and 70-200 2.8. There are more lenses but those seem the most relevant. I also have a 550 and 580ex with an ST-e2 which may come in handy but I'm not sure how.
Now, Ive got 15 people looking at me and that bag of equipment. What do I do about my light. I would assume I could shoot at 800iso comfortably and I would use about an 8 for my f-stop (assuming they are 2 deep).
So, what's next, please help.
I can tell him I'm not doing those shots or that he might have to pay for some new equipment as well.

I would shoot at iso 1600 indoors with your camera that would be no problem at all, a smaller range zoom would be nice but really you have all you need.
