What’s a Better Beamer? It’s not a hot-rodded BMW. It’s essentially a plastic fresnel lens that’s placed in front of your flash to concentrate the light beam using age-old lighthouse technology and physics.
A Fresnel lens projects the light beam farther then your flash can accomplish on its own. It does this by bending parallel light beams that would otherwise diffuse towards a concentrated point.
Many wildlife photographers find this type of flash setup useful for illuminating wildlife under forested cover and less-than-ideal lighting conditions. It also provides a nice catchlight in the eye, which helps bring subjects to life.
This photo was captured with the Sony A9, 100-400 GM lens, flash, and a Better Beamer.
