Tony Sleep: Very interesting combination of attributes, and promising. But aside from the question marks over pixel density issues and lenses that appear to be sized for similar "bigger is serious" marketing, I can see a potentially fatal flaw. Every camera I have ever used that has control wheels projecting from the back surface has suffered from the same problem, that they are hugely susceptible to being knocked off setting every time the camera brushes against your body.
Ergonomically this sort of control is just about perfect, but even with strong detents/friction you can never be sure the control is where you left it. You have to check actual settings every damn time before shooting, which ruins the flow of seeing, else risk ruined shots. Unless Sony have ensured the wheels are only "live" with the shutter is depressed, this is likely to be a huge issue. I look forward to reviews.
but sony smartly designed the straps so that the camera hangs with the lens pointing down. The back buttons point up and not back against your body.
