This Bower SFD450C e-TTL I/II external flash's adjustable, tilting head indirectly illuminates your subjects and reduces red eye while you snap photos with your Canon DSLR camera, helping to eliminate shadows and oversaturation for enhanced portraits.
it is a simple flash with no complicated setup buttons like other Canon, Nikon or others. All you need to do is to attach it to your DSLR camera and shoot. You can turn the flash up/down and sideway to allow less or more light. It is small so you can drop in your bag and go. I like it.
