Here is my real review after a considerable time of using the product Canon Speedlite 580EX Digital Cameras. Cool puff! Works flawlessly! the case is at the highest level (this is the smoothness of turning the head and pressing the buttons and the case which is not afraid of rain, it’s checked) Power is something. it’s better than 430th in everything, this is understandable . this is a top professional flash! a thing in a word.
