The Sony Cyber-shot DSC-RX100 IV Digital Camera is a versatile and advanced point-and-shoot featuring a large 20.1-megapixel 1" Exmor RS CMOS sensor to produce high-resolution still imagery and 4K video. This sensor's construction utilises a stacked backside-illuminated design to improve clarity and image quality when working in dimly-lit conditions as well as to increase its sensitivity to a native ISO 12,800. By completely placing the camera's photodiodes over the sensor's processing structure, the light-gathering ability of the Exmor RS CMOS sensor is further improved over previous backside-illuminated devices and faster image processing capabilities are added as well. 16 fps of continuous shooting is made possible as well as UHD 4K movie recording with the option of Super Slow Motion frame rates of up to 960 fps. Also benefitting the performance of this sensor is the BIONZ X image processor, which helps to produce images with smooth quality and tonal gradations.
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-shot DSC-RX100 IV Digital Camera is NTSC and PAL switchable, while utilising the XAVC S format to maximise high-bitrate shooting 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.
20.1 MP 1" Exmor RS BSI CMOS Sensor and BIONZ X Image Processor
The large 20.1-megapixel 1" Exmor RS CMOS sensor features stacked backside-illuminated technology to enhance its low-light capabilities over previous designs to a native ISO 12,800 while still retaining vivid clarity. By placing its photodiodes between the rear of the lens and sensor's underlying processing structure, the light-gathering ability of the Exmor RS CMOS sensor is further improved over previous backside-illuminated devices and faster image processing capabilities are added as well. 16 fps of continuous shooting is made possible as well as UHD 4K movie recording with the option of Super Slow Motion frame rates of up to 960 fps. Also benefitting the performance of this sensor is the BIONZ X image processor, which helps to produce images with smooth quality and tonal gradations.
UHD 4K Video Recording
Ultra-high definition video capture is made convenient with the ability to record short 4K clips of up to five minutes with no line skipping or pixel binning and with minimal moiré or visual aliasing. The XAVC S format is utilised to maximise high-bitrate shooting up to 100 Mbps for professional-quality video. When recording in either the NTSC or PAL video standard, 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. When set to 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. At resolutions below 4K, including Full HD 1920 x 1080p, movies up to 29 minutes in length can be saved.
Zeiss Vario-Sonnar T* Lens
The built-in Zeiss Vario-Sonnar T* 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 shooting conditions. An f/1.8-2.8 maximum aperture benefits working in difficult lighting conditions throughout the entire zoom range and also enables greater control over focus placement for shallow depth of field imagery.
Nine aspherical elements, including two AA (advanced aspherical) elements, are incorporated into the lens design to minimise chromatic aberrations throughout the zoom range to benefit creating sharp, clear imagery. The lens also features a Zeiss T* anti-reflective multi-layered coating to help minimise lens flare and ghosting in order to produce imagery with rich contrast and color neutrality.
Benefitting the 2.9x reach of this lens, as well as supporting working in difficult lighting conditions and with longer shutter speeds, is Optical SteadyShot image stabilisation, which helps to offset the effects of camera shake. Additionally, a neutral density 0.9 filter is incorporated into the camera's design, which provides a reduction of three stops in exposure to enable working in bright conditions with wider aperture settings and for greater control over how subject movement is rendered.
Within the compact design of the RX100 IV is both a high-resolution electronic viewfinder and a large rear LCD monitor. The 2,359k-dot SVGA OLED Thru-Finder EVF provides a bright, clear means for eye-level monitoring, which is well-suited to critical compositions and working in bright conditions. It features 100% frame coverage, and a unique pop-up mechanism. Alternatively, a 3.0" 1,229k-dot Extra Fine LCD screen is also available and features a tilting design (180° up, 45° down) to benefit working from high, low, and front-facing angles. WhiteMagic technology has been applied to the LCD's design, too, to increase effective brightness for easier viewing in bright lighting.
For intuitive, SLR-like adjustments over a variety of camera settings, a manual control ring surrounds the lens and features a smooth, click-less design for quick and quiet changing of settings. The ring can be assigned to control a variety of features, at different values, such as zoom, aperture, and Picture Effects. A step-zoom feature can be utilised, too, to allow instant switching between commonly used focal lengths.
Super-Speed Anti-Distortion Electronic Shutter
While a mechanical shutter featuring a top shutter speed of 1/2,000 second is suitable for most subjects, an electronic shutter provides the ability to capture at 1/32,000 second. This minimises distortion caused by "rolling shutter" which can become apparent when shooting fast moving subjects. This high-speed shutter also provides the ability to shoot 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 shutter speed and a built-in, three-stop ND filter which allows photos to be shot under extremely bright light at a maximum of EV19 with a fully open aperture setting.
Built-In Wi-Fi Connectivity with NFC
Built-in Wi-Fi connectivity enables instant transferring of imagery to mobile devices for direct sharing online to social networking, via email, and to cloud storage sites. NFC (Near Field Communication) is also supported, which allows for one-touch connection between the camera and compatible mobile devices, with no complex set-up required. Once connected, the linked mobile device can also display a live view image on its screen and, using Smart Remote Control, remotely control the camera's shutter release.
Additionally, PlayMemories Camera Apps are also supported via the built-in Wi-Fi connection, and allow you to personalise the camera's features depending on specific shooting styles. Apps are available to suit creating portraits, detailed close-ups, sports, time lapse, motion shot, and other specific types of imagery.
