I am weak on flash technicals. I know guide # of your flash unit and f stop affect distance. This device magnifies and narrows the flash for greater distance but I do not know how much. They say up to an extra 2 1/2 stops. The formula for stops to distance is unknown to me. I just know this unit helps to obtain captures you would miss with out it.
