ANy one used or set up a flash extender such as the better beamer?? The inst. suggest setting to 50mm zoom, I am using D3/D700 and 70-200 VR./Sb900 my inside test at 8m shows a norrow band of light and I would expect a central concetration. Also for use "birding" outdoors in shaded trees will I have to stick to 1/250th shutter to sync??
Any tips welcome--jim-I Also will try thus on the 200-400
