The Visual Echos FX4 Better Beamer Flash Extender will help increase the reach of the flash and increases the flash output by about 2 to 3 f/stops. It focuses and concentrates the output of the flash into a narrow beam via the fresnel screen that gets positioned in front of the flash. This allows shooting at greater distances and shooting with smaller apertures.I excitedly attached my Better Beamer to my flash, set it up on my camera along with my BML (Big Manly Lens), and aimed it at a blue jay across the yard. I focused in, pressed the shutter release, and POP! The bird exploded in a cloud of feathers.
WARNING: NEVER ATTACH THE FRESNEL BACKWARDS.
