The SB-N7 fits the design already time for my Nikon V2. Unfortunately, the otherwise really very compact V2 is therefore somewhat unwieldy = high. One notices the better illumination at depth for built-in flash. Nevertheless, a guide number of 18 is not much. If I need a flash only for lightening and does not want to shed light on a smaller hall, the already built in the V 2 flashes enough for me in many cases. Because the price is a bit steep, as the Chinese competition is missing, you should really try out how much gain the SB-N7 really brings.
