Rogue Safari Pop-Up Flash Booster
Rogue Safari focuses the light from a DSLR's pop-up flash to greatly increase the available flash power at extended distances.
Safari is designed to work with crop-sensor (APS-C/DX) Canon and Nikon DSLRs. While the Rogue Safari Pop-up Flash Booster is compatible with the vast majority of modern DSLRs, some early model cameras, including the Canon 10D, 20D and 30D will not accommodate the adapter
