i currently use a 580exii but ive been told that the metz flash syncs better with the canon camera ..is this true ?? if not i also need to but a quantum battery pack or something and again i heard that metz re-charges quicker with the battery pack ...??
what do you guys use...as this is for weddings and i use my flash alot!!! batteries just wont do anymore lol !!!
any advice or recommendations on this as i need to get something this week as i have a wedding on sunday to do !
