Review on Enhance Your Photography with the Canon Speedlite 580EX II Flash for Canon EOS Digital SLR Cameras by Jasmit Singh ᠌

My personal experience of using the product Canon Speedlite 580EX Digital Cameras. The head is slightly loose. Also, the shoe mount also sometimes staggers, generating false puffs at the same time - but here the problem is more likely in the camera itself. When the lamp degrades, the IGBT transistor may fail, as a result of which the flash will either not work at all, or will always shoot at full power. It is treated by replacing both.
