This week marks the start of Photokina, the camera show where pretty much every brand will unveil their latest and greatest pieces of kit. We'll hear from everybody in due time but right now, Samsung is in the hot seat. The tech giant just unveiled the NX1, the company's first camera that records 4K video. In addition to doing UHD footage at 30 or 24 frames per second and Cinema 4K at 24fps, it shoots stills with a 28.2-megapixel backside-illuminated APS-C CMOS sensor. In burst-capture mode, you can snap up to 15 frames per second at full resolution. ISO sensitivity now ranges from 100 to 51,200. Similar to the NX30, a more mid-range camera in Samsung's lineup, this has WiFi and NFC, along with a 3-inch Super AMOLED articulating display and a 1,366 x 768 electronic viewfinder. In this case, though, it's 802.11ac WiFi, there's Bluetooth too, and the EVF promises a shorter lag time of around 5ms.
