I have used an Olympus SP350 in Olympus housing with Olympus UFL-1 slave strobe while snorkeling. I am in the process of upgrading to the S90 which I just purchased. I will need to purchase a housing and have not yet decided between the Canon, Ikelite and new Fisheye when available (quite a bit more expensive). Is there a way to use my Olympus UFL-1 with the S90 in any of these housings? I plan only to be snorkeling and so I don't need a very bright strobe. The UFL-1 is not very powerful and is similar to the Sea and Sea YS-17. I was able to use the UFL-1 with the Olympus camera without a fiber-optic cable since the flash recognized the camera's flash. Will I need a fiber-optic cable to use the UFL-1 with the S90 in all of these housings? Any suggestions. Thank you.
