Wasn't sure where this should go. I'm going to be the main photographer for my mom's wedding. It's a not going to be a big event, just with close family. I was curious as to which size lens would be most helpful... I'm thinking I'll use my 40-150 mm lens...? And have you found any good resources or books worth recommending? Any basic tips or anything would be helpful, too. I've been reading a wedding photojournalism book which I'm more interested in than traditional wedding photography.
