Chris,
All photo's and video were taken with the S8000 in Ikelite's #6184.80 case and Ikelite's AF-35 strobe. I did have a diffuser on the strobe and applied a very small amount of sticky foam to the inside of the case where the camera lens fits. There was a small gap there that was letting in light from the internal flash causing a halo effect. Once that gap was covered the problem went away. Hope this helps.
