I'm shooting my sister's wedding in December. I'm pretty sure it's all going to be indoors. I consider myself to be a beginner and I don't have experience with different types of lenses.... does anyone have any suggestions? I plan on renting a couple of lenses before the shoot to try them out to see which ones I like. I am looking for a wide angle lens for sure. Please don't badger me about, "Why are you shooting a wedding, leave that up to the pros". I have already discussed with my sister that I am not a professional, but she still wants me to do it. This will be my third wedding, so give me a break. Anyway, I have the Canon Xsi kit lens and the 50 mm 1.8 already. Which lenses do you suggest that I try out? Thanks in advance for useful information!
