FYI, user Boaz has some diffuser film available that is reported to spread out the beam similar to an elliptical optic. I believe he mails it in a standard envelop to keep the shipping cost low, and he indicates he can send it internationally. See what he lists as #5. Also get yourself a sheet of #1 if your order from him.
I don’t know if it works as well as the Carclo 10510 optic, but I have some on its way, and will try to find time to do a couple quick test shots once I receive it.
