So my sister-in-law has asked me to take pictures of their wedding day There will be an "official" photographer for the more ceremonial part of the evening, but it's an all-day affair with lounging by the pool and games on the grass during the day and then a short ceremony and dinner at night. Plus the rest of the weekend. She was clear that I was to enjoy myself first but since she likes my photos she asked if I could capture moments here and there. However... I am not set up to shoot a wedding! I have sold off a bunch of stuff and I'm basically down to my Ricoh GRD4 and Ricoh GXR A12s and A16, none of which is well suited for wedding photography (for one thing, AF is slow - my own photography is more methodical and speed is not an issue). My question is, can you recommend the right camera/lens combinations for my needs? I can rent gear (and rent it long enough to practice with it first), but I may also take the opportunity to try the Olympus E-M5 if one can be had. I would prefer a serious compact but perhaps a smaller DSLR is the right choice? A zoom lens is probably the right approach with fast prime use here and there. Good higher ISO performance is probably a wise choice. I'm more than happy to help take pictures at the event, but I want them to turn out good, plus I don't want to burden myself with too much gear. Your recommendations are appreciated! Thanks.
