I was just wondering about this issue..
When firing the flash directly at a subject, I've experimented with pulling down the 14mm diffuser panel to create a softer light even though I don't need the angle of coverage it provides. It does produce a noticeable, substantial softening of the shadows behind the subject for the situations where I can't bounce.
Is there any difference between this method and using a Stofen omnibounce to diffuse the light in direct flash mode? I'm just wondering whether to buy it.. if it provides better diffusion in direct mode than the panel, I'd consider it, if not, it's one less piece of gear to pay for and carry.
I'm aware this is not the intended use of the Omnibounce. In bounce mode, I'm very happy with the results from my bounce card with rubber band
