Have you not read this thread Joe??
Eventhough Joe does have a vetted interest, I think it was ok to remind us what is possible in certain lighting conditions. Each and everyone may estimate is his/her diving range (shallow water) and video shooting needs similar to the samples. For example macro shooting under well-lit artificial lighting might be totally ok. And whether the picture quality, tonal range and slight red rings are acceptable or not.
These samples also confirm that even with multiple different shooters the red rings might and do appear. I was initially concerned that the problems might have been related to individual cameras and/or personal settings on the camera.
Hopefully Sony will fix this.
