Visual Echoes FX3 Better Beamer Flash Extender for Use with Telephoto Lenses

The Visual Echoes FX3 Better Beamer Flash Extender will help increase the reach of Canon 580EX, 580 EX II, 600EX-RT, Nikon SB-700 and Metz 54MZ-4 flash units, 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 panel that gets positioned in front of the flash. This allows shooting at greater distances and shooting with smaller apertures.
