As cabinetmaker (yep that`s my real job) we Do love clamps, without them we couldn`t get things done. As photographer I think kind the same way, clamps can really help to put a light exactly where it needs to be, sometimes you really need to control that, cause light from a speedlight goes everywhere. Manfrotto’s „Justin Clamp 171“ is just the right tool! It has a coldshoe mounted on a mini ballhead, just like on a tripod wich means u can go almost 360 degree with yr flash. It holds easily a SB900 or a Canon 580EX Flashgun. Pretty versatile and very…very handy!
