Tom Goodman: The 1" sensor in the new Sony Cyber-shot DSC-RX100 is more attractive than the fast lens here. Still, with the innovations taking place in other Samsung product lines, this camera is worth handling and testing. An articulated screen is a luxury these days in quality cameras within each class but it should be standard.
The sensor in the Samsung may be much smaller than the Sony's, but if seen from the perspective of pixel density, then the gap narrows anyway.
Great work Samsung! They seem to have taken everything that was good about the EX1 and improved it without changing the core principles of the camera. I have greatly enjoyed ownership of the EX1 for many years and am happy to be able to update my camera rather than having to replace it with something completely different.
