To make ultra-high definition video captures convenient, short 4K clips of up to five minutes can be recorded with no line skipping or pixel binning as well as with minimal moiré and visual aliasing. The Sony Cyber-DSC-RX100 IV Digital Camera is NTSC and PAL switchable, while utilizing the XAVC S format to maximize high-bitrate up to 100 Mbps for professional-quality video. When recording, creative potential is further extended with the ability to capture Super Slow Motion High Frame Rate movies at up to 40x slower than real time. These slow motion clips are recorded at 960 fps, 480 fps, or 240 fps and can then be played back at 1920 x 1080, in 60p, 30p, or 24p, when the camera is set to NTSC. For PAL, slow motion clips are recorded at 1000 fps, 500 fps, or 250 fps and can then be played back at 1920 x 1080, in either 50p or 25p. While recording at video resolutions lower than 4K, such as Full HD 1920 x 1080p, video clips up to 29 minutes in length can be saved.
The Sony Cyber- DSC-RX100 IV Digital Camera's enhanced Exmor RS CMOS sensor also helps to supplement the camera's top mechanical shutter speed of 1/2,000. It does so by enabling electronic shutter speeds of up to 1/32,000 second which minimizes distortion caused by "rolling shutter" which can become apparent when fast moving subjects. Additionally, this high-speed shutter provides the ability to photos with defocused backgrounds even while using large aperture settings under very bright lighting conditions. This is achieved by a combination of the 1/32,000 second electronic shutter speed and a built-in, three-stop ND filter that allows photos to be under extremely bright light at a maximum of EV19 with a fully open aperture setting. The built-in Zeiss Vario-Sonnar T* 2.9x zoom lens provides a 35mm-equivalent focal length range of 24-70mm, covering wide-angle to portrait-length perspectives to suit working in a wide variety of environments. An f/1.8-2.8 maximum aperture benefits working in low lighting and controlling focus throughout the zoom range. Optical Steady image stabilization is also available to help minimize the appearance of camera shake when working in dimly-lit conditions and with greater zoom magnifications. The lens also features a Zeiss T* anti-reflective coating, which helps to reduce surface reflections, lens flare, and ghosting in order to produce imagery that is rich in contrast and clarity.
Complementing the imaging capabilities of the RX100 IV is a sleek body design featuring both an electronic viewfinder and an LCD screen. The 0.39" 2,359k-dot SVGA OLED Tru-Finder has provides a bright, clear means for eye-level viewing. It features a unique pop-up mechanism that helps to maintain the compact form factor of the camera when carrying or if preferring to work with the rear screen. The 3.0" 1,229k-dot Xtra Fine LCD incorporates WhiteMagic technology for easier visibility in bright conditions and its tilting design permits greater usability from high, low, and front-facing angles. Furthermore, built-in Wi-Fi connectivity with NFC allows instant image sharing to, as well as remote camera control and monitoring from, linked mobile devices.
