Camkitmate Softbox Bounce Flash Diffuser For Canon Speedlite 270EX FLASH The diffuser is used to create exposures of even density over the entire surface of film. Use the diffuser by placing it flush against the front of the lens and exposing through it. Flash straight on if without our diffuser causes the light to go forward only and creates a harsh shadow behind the subject. This fits cleanly over the head of your existing flash, no need for cumbersome attachments, hooks. Try us and see the difference. It disperses the light over a wider area for a softer, more balanced and natural effect than you didn't use before. It helps to reduce hard background shadows and eliminates the annoying red eye effect. What you will get: 1 x Canon Speedlite 270EX Diffuser
