Bought for my wife who is starting her professional photography business. She really likes her Canon 50D and Speedlite 580EX II Flash. Both bought on Amazon perfectly new for an amazing price. She really likes how easy and secure it is to attach and unattach the flash from her camera compared to the Nikon D200 her college rented her.Get more detail about Canon Speedlite 580EX II Flash for Canon EOS Digital SLR Cameras.
