Yes this is the last bit of Nikon kit I am no longer keeping the Nikon SB900 flashgun. so advertised it on another forum.
It is amazing how much one keeps even when changing brands.
Going from Nikon to Panasonic is not just a camera change over, but lenes -instruction manuals - diffusers- filter etc etc. one thing i do is keep all original boxes gear comes with as it helps when time to sell.
