Hi guys, I posted much the same question over on the sister site and it's this; does anyone know what one of these light rings is worth? It comes complete with controller for dimming the output but no chromatte backdrop. As I always say, if not for buying and selling camera gear I'd be unable to afford any upgrades for my m4/3 system. I have no clue when it comes to this type of specialist photography, I got a good deal (I think) but really don't know what sort of resell price I'd get for it on the second hand market. Your input is very welcome!
