This would seem to be a good opportunity for a real-world test of the K30?

Haven't managed to track down the original article, but it's reported on the other Forum that Pentax Ricoh have announced they are re-positioning the brands so that 'Pentax' will only appear on ILC's and 'Ricoh' on compacts.
The quote, (from the Asahi Shimbun newspaper, courtesy of Google translate), is as follows;
"Noboru Akabane president of Pentax Imaging Ricoh, has announced plans to abolish the future of Pentax compact digital camera, SLR digital camera to focus on. Hopes to bring back the fans with high-performance line. SLR is a Pentax compact is under consideration in the direction of a unified brand of Ricoh."
Wonder where the Ricoh GXR will end up? Should be Pentax.

I'm not totally convinced that at normal distances and apertures this makes very much difference. At macro distances and very wide apertures it may well do.
Thanks John. Still don't get it. If I stand and focus on a person's eye, then rotate/pan the camera down so as to include their whole body, the distance from the camera to the eye remains the same surely? The point of focus is following an arc with the camera's sensor at the centre.They are saying that if you use the centre point only and then move the camera, say, downwards to recompose, the distance from the point the eye registers on the sensor to has changed, slightly altering the focus point.

"So why do I need to use the outer focusing points to begin with? Why couldn’t I focus and recompose? Because then I’d throw of the plane of focus. It would be nice of Pentax utilized something like Hasslebald’s TruFocus system that was designed for those types of photographers."
From the review. Anyone care to explain this to me please, in particular the '..plane of focus.' thing.
