Most of my wedding photography is done with Noemi Hedrick of noemiphotography.com. I often use my Canon 70 - 200mm lens during wedding shoots. It's a portrait lens that also works for group shots.
People will ask me if I take wedding photos and I say, "Yes", but in the next breath I'll recommend Noemi because she is great at setting up shots and making everyone laugh and have a good time. I love working for her and people love having her as their photographer.
