Negative Positive
Title: Works well until it fails
Review: The 580EX II is prone to failure. With minimal use, mine failed in less than a year. At first it occasionally misfired, giving blank black pictures. Cleaning the contacts and sliding it on and off the camera seemed to help at first. Now it is just plain dead. I've missed numerous photo opportunities forever.Search the web and you'll find many forums devoted to the various ways this flash can die.Most disappointing is the short warranty. Canon gave me a repair estimate of $180. I paid $450 for the flash unit 10 months ago. This is not right.Other info: The flash was used exclusively on a Canon Eos 7D camera. Used for approximately 1,000 flash photos. With a total cost of $630 for the 580EX II, that comes to $.63 per flash actuation. Not exactly a fun way to enjoy my photography hobby.
