No New Diffuser -Again

A set of Nikon SW-11s arrived in the mail today and I after modding them to let more of the light from the MT-24EX's flash heads into the first internal reflector the Puffer set that I made is back on my flash heads. When I first tested the SW-11s (shooting one of my son's Hot Wheals cars) I was losing almost four more stops than the Puffer set, and after modding them I was only able to regain one more stop. So with the Puffers I lose one stop of light compared to the bare flash heads, and with the modded SW-11s I was losing three. The diffusion with the Puffer set was also better, but I'm not going to bother posting test shots since losing three stops of light is losing two stops too much. I can't recommend the SW-11s as a diffuser for the MT-24EX

The SW-11s use two reflectors to bounce the light from the flash into a diffusion panel. Oddly enough the first reflector looks like it's at the wrong angle and it seems to me that it's actually doing more to bounce the light from the flash right back toward it instead of bouncing it to the second reflector. One possible mod would be to change the angle of that first reflector, or replace it with something that would bounce the light in the right direction. But I didn't see enough room inside the diffuser to pull it off and I'm not sure it would make much of a difference. With every reflector I'm probably losing a stop, so at a minimum the best I'd be able to do with the SW-11s is to lose two stops. Not worth it...
