Killer 4K? Sony Cyber-shot DSC-RX100 IV first impressions updated with video samples

Our Sony Cyber-shot RX100 IV first impressions continues to grow as we've added a variety of video samples to the preview. The RX100 IV is Sony's latest enthusiast compact, and its 20MP 1"-type stacked CMOS sensor is capable of 4K video and slow-motion clips ranging from 120-960 fps, all with virtually no rolling shutter. We put a number of these modes to the test.
