Review on The Flash X-Tender Better Beamer FX-6: Enhancing Nikon SB-900 Flash Output by Evan Zurlo

What can I say? This is probably the most useful accessory I've ever had for my dollar-for-dollar wildlife photography. Shots that I could never properly expose for hidden creatures or on less clear days are now not only properly exposed but seem to stand out in photos. An additional advantage is that I can use lower ISO settings and my flash batteries last longer because I can "underpower" the flash a bit (mostly -0.3 to -0.7 flash power). A word of warning, and that is common sense: It is a FRESNEL that Gathers and FOCUSES LIGHT. DO NOT leave unattended in bright/direct sunlight. He will melt or burn whatever he shines the sunlight on, just as a magnifying glass burns grass or a tree.
