The Vello Bounce Dome Diffuser for Canon MT- 24EX Speedlite (Set of 2) softens the light output of a flash, reducing harsh shadows that are often the result when using direct illumination. The dome provides even coverage across the entire frame and is ideal for use with lenses from 15mm to 200mm in 35mm format as well as their equivalent in other formats. Since each Bounce Dome is custom made for the flash, it slips on and off without the need for touch fastener tabs.
