Sigma EM-140 ring flash holder

A common regret when photograph work with a macro ring flash is that the image seem flat. This is due to the lack of shadow caused by the fact that the light come from the point of view: the same effect appear you use a headlamp by night.

This tool permit to hold the flash in a better position. It have 3 easy freedom degrees :
* the angle of the camera fixation,
* the angle between the two threaded rod and
* the angle of fixation of the flash.

Note that I add 2 grips from [MaxGlide](htt
