The Canon Speedlite 580EX II flash is the premier flash camera for all photographers, including professionals. Improvements have been made to match with the EOS-1D Mark III in terms of body strength, and the ability to control flash functions and settings from the camera menu (EOS-1D Mark III only). This Canon camera flash light time is 20% shorter than the 580EX and is completely inaudible. Sports and photojournalism photographers have a reason to rejoice as this is the first Canon compatible flash that is weather-resistant. It is dust and water resistant for added performance. Youll enjoy improved communication reliability through its direct contacts.
