Is the price difference in the 580EX II and the Metz 76MZ-5 Digital worth it?
I do some events and a lot of out doors portraits. I am using a 50D and a 30D for back up. I have a 580EX II with the CP-E4 battery pack now but it starting to give me a little trouble, it miss fires and I think it is time for a new one. I am using two 430EX’s for back up.
Thanks for the advice.
