I own a Nikon 1 V1 and this Speedlight reminds me of the original SB-N5 Speedlight for that camera. Like it the SB-300 is small and will fit nicely in my Nikon camera bag at one end. It runs on 2 AAA batteries so unlike the SB-N5 you will need to keep a couple handy at all times. The SB-N5 is powered by the internal battery in the camera. Not so with the Nikon Coolpix P7800 which uses a smaller battery and thus requires external ones for its flash.
