Sony has announced two Cyber-shot cameras, the compact RX100 IV and high-zoom RX10 II. The two new models both feature the world’s first 1.0 type stacked Exmor RS CMOS sensor with advanced signal processing and an attached DRAM memory chip. Sony says the high speed signal processing and DRAM memory chip work together to enable more than 5x faster readout of image data and are responsible for a variety of standout features that have previously been available in only a select few professional-level video cameras. These include 40x super slow motion video capture at up to 960 fps, an ultra-fast Anti-Distortion Shutter with a maximum speed of 1/32000 second, and high resolution 4K movie shooting.
Prior to shooting, users will have the ability to choose among 960 fps, 480 fps and 240 fps frame rates and among 60p, 30p and 24p playback formats, with the option to use the movie record button as a ‘start trigger’ to begin recording once button is pressed or ‘end trigger’ to record footage up until the button is pressed. The ‘end trigger’ mode lets shooting begin 2 to 4 seconds before the movie button is pressed, enabling shooters to capture the decisive moment with much more consistency and accuracy. For reference, two seconds of movie footage shot at 960 fps and 24p would take about 80 seconds to play back.
Sony adds the speed and power of the sensor with an attached DRAM chip allows the new cameras to perform exceptionally well while capturing fast-moving subjects. Specifically, it’s fast processing capability results in continuous speeds at up to 16 fps on the RX100 IV and up to 14 fps on the RX10 II for an extended period of time.
Additionally, the ultra-fast readout of the image sensor is responsible for the high speed Anti-Distortion Shutter, which allow the new cameras to capture sharp, crystal clear images with a wide open aperture at brightness levels up to EV197. It also minimizes the “rolling shutter” effect commonly experienced with fast moving subjects. This, notes the company, allows photographers and videographers to capture beautiful content with sharply focused subjects and defocused backgrounds under some of the most difficult, bright lighting conditions.
The cameras offer 4K (QFHD 3840×2160) movie recording. The cameras utilize full pixel readout without pixel binning to ensure that all the finer details of 4K video are captured with minimal moire and ‘jaggies.’ These high-quality results are achieved through use of the XAVC S codec, which records video at a high data rate of 100 Mbps during 4K recording and 50 Mbps during full HD shooting.
The capacity for shooting 4K differs slightly on each of the two cameras, as the more professionally styled RX10 II can shoot 4K video at extended lengths (up to 29 minutes in the US), while the more casual, pocket-friendly RX100 IV can shoot 4K clips at up to about 5 minutes in length. Additional professional calibre video features on both of the new cameras include Picture Profile, S-Log2/S-Gamut.
Both cameras also have advanced dual video recording functionality, allowing shooters to capture 16.8-megapixel still images during 4K video recording in any of 11 different composition patterns simply by pressing the shutter button.
The RX100 IV maintains the compact, pocket-sized design of the RX100 family, and has a Zeiss Vario-Sonnar T* 24-70 mm (equivalent) f/1.8-2.8 lens, while the RX10 II maintains the same body design as the original RX10 and has a Zeiss Vario-Sonnar T* 24-200 mm (equivalent) f/2.8 lens.
Each of the cameras is equipped with a new high-contrast XGA OLED Tru-Finder for true-to-life image preview and playback functionality. The RX100 IV maintains the retractable EVF with Zeiss T* coating from the RX100 III model.
Both of the two new models feature an upgraded Fast Intelligent AF system that enables high-speed, high-precision contrast detection of a moving subject in as little as 0.09 seconds. Sony’s proprietary AF algorithm allows them to recognize and lock-in on a subject with a simple half-press of the shutter button at a much more efficient rate compared to previous models. The new cameras are also Wi-Fi and NFC compatible and can access Sony’s growing range of PlayMemories Camera Applications.
Both of the new models feature a variety of customizable controls and buttons. The RX10 II adds dust and moisture resistance as well.
The new Sony Cyber-shot RX100 IV and RX10 II will be available in July.
