Well, I received the 10°, 20° and 30° circular diffusers in a few days ago. Only problem is the 30° came in a 3mm thick panel instead of film. So I’m waiting on the 30° film. Will upload beamshots off all three using a Convoy C8 XPL HI, and an S2+, to give you an idea of the different levels of diffusion.
Meanwhile, I bought one of the Reylight Pineapples, and stuck a 10° diffuser in between the reflector and the glass. The beam is buttery smooth now, with hardly any loss. Here’s what the non diffused beams look like. I have the ringy reflector, not the upgraded one.
