Clive francis, you're right on all those points. I have great difficulty however getting such reviews on underwater cameras, and even less outside the high-end (professional) and/or Olympus-made models. As I previously mentioned, underwater photography is a niche market. There's far less consumer drive for comprehensive professional reviews. If someone could post links to such reviews, that would be fantastic.
And I love word-of-mouth reviews, and use them a lot. But they're a lot like my local dive shop... they only are experts on what they have, and tend to not know (or sell!) much about what else is "out there." My camera shop also recommended me to an Olympus C-series camera when I visited them months ago, but candidly admitted to not being "up on" the other manufacturers. I got suspicious of that and held off.
Rather than nitpick me to death (and it IS upsetting me!), what I believe the thread originator wants (and what I was hoping to see too HINT HINT) is a list of nice alternative cameras. They don't have to compare to the C5050, they merely have to be "nice underwater cameras," and not any more expensive than a 5050 or 5060. That's most peoples' cutoff.
