What sensor does it have? The guys at thecamerastore did a preview video with a preproduction model and they say that it is a brand new sensor (not just like the K5). Would Sony give a new sensor to this camera (and to the Ricoh, as it has the same size sensor - both 0.1/0.2mm bigger than the Sony 16mp)? Is it from Aptina?
Alizarine: Could this be the K-5 sensor in that module?
The sensor on the K-01 is almost certainly not the same as the nex5n. See the camerastore video preview, where they have a preproduction model and state that the sensor is not the sony 16mp from the 5n. It's a different size for a start, but only by 0.2 or 0.1 of a mm. However, it's the same size as the sensor in the new Ricoh module - they probably share the same sensor. The autofocus speed on the K-01 looks decent from the WDC preview video, maybe it will be decent in the Ricoh, too.
