i've been asked to take photos at my niece's wedding reception this September. The question that I keep asking myself is whether or not I would be better off using my Canon gear as I already have a flash for my 1Ds mark 2 and 5D classic or am I better picking up a flash and using my OMD E-M1 and E-M5? I have the Canon 24-105 f4 that I would likely use with the DSLRs. For my OMDs I would likely use primes although I have the 12-50 kit lens. I really like my OMDs but on previous occasions where I've shot family events J used my 5D or 40D. My niece has said she wants nothing special, just photos of the day.
