Hello PF peoples, I'm a an amateur photog who really just got started last year. I've used an SLR camera before but this is my first DSLR, and the first time I can say I really understand the basics of photography. I'm having fun trying everything out from macro to video. In May my Sister is getting married. She has hired a professional photographer but has asked that I bring my camera along to take candid shots. I own a Canon 60D with the kit 18-135mm IS lens and a 50mm f/1.8 prime. This seems an excellent excuse to rent and try some new gear! I plan to rent the gear once to learn how to use it and again for the wedding if I can't afford it outright. Any advice regarding the following kit for the event or candid wedding technique would be much appreciated. Here's the gear I'm looking at...http://www.borrowlenses.com/product/canon_flash/Canon_Speedlite_580_EXII The wedding, weather permitting, will be held outside. I don't have any experience with a big boy flash but figure to use it for fill light and shadow reduction outside. If the weather goes bad it's there for indoors as well. Maybe, the 580 is over the top? I've also heard that RF controlled flashes are coming out. Regardless, I need to learn how to use a proper flash. http://www.borrowlenses.com/product/canon_standard/Canon_24-70mm_f2.8_L I think this may be the only lens needed, though the x1.6 crop on 60D remains a question. Is the quality compromised? It becomes a 38-112. Should I find a wider angle lens for candid shots? Don't think I'll be able to afford this lens but I'm dying to try it! I'm looking to use http://www.borrowlenses.com for rental. Happy Shooting!
