I bought the 6000-series of this model camera and used in the sea once. The overall color is good and accurate in well lite environment. However indoor, dark room shots are very poor with over aggressive software correction which results in lost of details. Even in ISO 400 the over correction by the software is very obvious.
The underwater tricks work flawlessly. However potential buyer should beware of this catch. The instruction manual has a small print saying that the rubber seals on this camera should be replaced annually if you plan to use this camera in water a lot.
Another problem with this camera is that the lens has a cover which closed when powered off. This traps moisture if you have used it under water for some time and will not allow the lens area to dry problem. In the long run, this could be a potential problematic area.
