The Flash X-Tender () FX-1B Flash Output Booster for Nikon SB80, SB80DX

Been using on my Pentax fgz 360 flash for bird photos. Its helped somewhat. Its a bit flimsy and rather overpriced, but there's not much as an alternative other than making your own. I made my own with a map magnifying Fresnel lens I bought at the dollar store, and some sheets of cardboard and duct tape. Its quite a bit larger and more awkward than the Better Beamer, but a lot cheaper and does the same thing. I've also compared this Better Beamer on my FGZ360 to using just a Sunpak 622 Super with the zoom head. The illumination is about equal, but I am limited to a sync speed of 180 with the Sunpak. So for birding with a 300mm or longer lens, the Better Beamer on the fgz360 lets me sync at 1/320 or whatever speed I need. But if I'm shooting with an old manual lens, the Sunpak is an easier, though bulkier, setup.
