I have a Canon 50 f1.8 and a Canon 70-300 f4. Will these two lens be good to shoot an indoor wedding? I will be looking at the venue this Friday, so right now not real sure about the lighting inside. Right now all I have for external light is a Canon 420EX. (posted a question about it also). This will be my 1st wedding in August. Our son has shot approx. 8 weddings and he is going to be the shooter for the formals and I'll shoot mainly the reception. Thanks for any replies I receive from you guy's and gal's. Stephen
