Through research, I know that the Sunpak PZ-42X is similar to the Fujifilm EF-42. Because I have the Fujifilm flash unit, I have therefore ordered this flash diffuser. That part comes from abroad, so the delivery took a week. But so that I could live well, because the soft box is completely fit, does not slip by lightning and served its purpose very well.
The diffuser produces - especially in portraiture - a softer light. Even if "bounced" against the ceiling, it branches by its construction some of the light to fade in color towards the front.
