Flash Setting Guide

This is a general guide to setting the flash angle for various magnifications with a macro lens. Refer to the angle scale (15° increments) on the side of the flash head and set the same angle for both flash heads A and B. The angle specifications in the table below indicate the inner angle relative to the flash head’s standard position index (horizontal).
