In addition to previously released –0.5 and –3 diffusers, Inon Japan has developed a –1.5 system, for greater ability to widen and soften strobe light, and control flash output. Each diffuser includes a “Light Filter Set” consisting of red and blue filter inserts. The filters snap into the diffuser to correct strobe’s focus light color temperature, useful in some conditions. These new diffusers will be available from Inon America in late April.
