Guys, Thanks for the insights. I had been looking at the bag and it seems like the overall feedback is that they are OK yet can be somewhat challenging to manage the camera. As for light, they do offer a bag that has space for the speedlight. At this time it looks like I wont be using any SCUBA and will only be snorkeling so I will be somewhat closer to the surface and may be OK with the limited ability of a speedlight for bringing out some of the color. Did see a Chinese Hard Case for about the same money as the EWA Marine bag, yet can't find any users with real feedback. I'm still 2 months out from my trip so I will continue to investigate,
