Sony Cyber-shot RX100 IV and RX10 II shoot 4K video
June 11, 2015
Borrowing technology from Sony’s professional video cameras, the 20.1-million-pixel Cyber-shot RX100 IV and 20.2-million-pixel RX10 II are built to be capable of shooting video at up to 40x slower than the standard rate (at up to 1,000 frames per second).
The ‘pocket-sized’ RX100 IV sports a Zeiss Vario-Sonnar T* 24-70mm f/1.8 lens (in 35mm terms), while the RX10 II comes with a Zeiss Vario-Sonnar T* 24-200mm f/2.8 zoom.
The Cyber-shot RX100 IV and RX10 II use a 1.0-type stacked Exmor RS CMOS imaging sensor, claimed to deliver advanced signal processing, and a DRAM memory chip. These join forces to boost image data readout by more than five times, claims Sony.
The RX100 IV delivers continuous shooting up to 16fps, while the RX10 II can shoot at a maximum of 14fps, according to Sony.
In a statement, Sony said: ‘Both cameras also have advanced dual video recording functionality, allowing shooters to capture 16.8 MP still images during 4K video recording in any of 11 different composition patterns simply by pressing the shutter button.’
Both models incorporate a new ‘high-contrast’ 2.35-million-dot resolution XGA OLED Tru-Finder.
UK prices and availability have yet to be announced.
FULL PRESS RELEASE
Sony – Jun 11, 2015 08:00 BST
New Compact RX100 IV and High-Zoom RX10 II models boast world’s first stacked 1.0 type CMOS sensor with a DRAM memory chip, 40x super slow motion capture, 4K video shooting, high-speed anti-distortion shutter and more.
Sony has today announced two of the most advanced, versatile Cyber-shot cameras ever to come to market, the compact RX100 IV (model DSC-RX100M4) and high-zoom RX10 II (model DSC-RX10M2) cameras.
The two new models both feature the world’s first 1.0 type stacked Exmor RS CMOS sensor[i] with advanced signal processing and an attached DRAM memory chip. The high speed signal processing and DRAM memory chip work together to enable more than fives times faster readout of image data[ii] and are responsible for a variety of standout features that have previously been available in only a select few professional-level video cameras. These impressive capabilities include 40 times super slow motion video capture at up to 1000fps,[iii],[iv] an ultra-fast anti-distortion shutter with a maximum speed of 1/32,000 second, high resolution 4K movie shooting[v] and more.
Up to 40 times super slow motion shooting
A first for Sony consumer cameras, the new RX100 IV and RX10 II both have the ability to record super slow-motion video at up to 40 times slower than the standard rate, allowing users to capture and replay fleeting moments of action with incredible detail, resolution and clarity.
Prior to shooting, users will have the ability to choose among 1,000fps, 500fps and 250fps frame rates and among 50p and 25p[vi] playback formats, to optimise the recording to fit the speed of the moving subject, 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 two to four 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 1000fps and 25p would take about 80 seconds to play back.
High speed shutter, high speed shooting
The impressive speed and power of the 1.0 type stacked Exmor RS CMOS sensor with an attached DRAM chip allows the new RX100 IV and RX10 II to perform exceptionally well while capturing fast-moving subjects.
Specifically, its 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 (maximum speed of 1/32000 second), which allow the new cameras to capture sharp, crystal clear images with a wide open aperture at brightness levels up to EV19[vii]. It also minimises the ‘rolling shutter’ effect commonly experienced with fast moving subjects. This allows photographers and videographers to capture beautiful content with sharply focused subjects and defocused backgrounds under some of the most difficult, bright lighting conditions.
High precision direct 4K movie recording
The new RX100 IV and RX10 II models are the first Cyber-shot cameras to offer the advantages of 4K (QFHD 3840×2160) movie recording. The cameras utilise 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 Europe), 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, and more.
Both cameras also have advanced dual video recording functionality, allowing shooters to capture 16.8 MP still images during 4K video recording in any of 11 different composition patterns simply by pressing the shutter button.
Versatility in design, high speed AF
The new RX100 IV maintains the compact, pocket-sized design of the RX100 family, and has a ZEISS® Vario-Sonnar T* 24-70mm (35mm equivalent) F1.8-F2.8 lens, while the new RX10 II maintains the same body design as the original RX10 and has a ZEISS® Vario-Sonnar T* 24-200mm (35mm equivalent) F2.8 lens.
Each of the cameras is equipped with a new high-contrast XGA OLED Tru-Finder™ with approximately 2.35 million dots of resolution, ensuring true-to-life image preview and playback functionality. The RX100 IV maintains the convenient retractable EVF with ZEISS® T* coating from the RX100 III model that debuted last year.
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[viii]. Sony’s proprietary AF algorithm allows them to recognise 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. Learn more at www.sony.net/pmca.
Aesthetically, both of the new models feature a variety of customisable controls and buttons to fit any shooter’s style. The RX10 II adds dust and moisture resistance too.
A new stylish soft carrying case for model LCS-RXG has also been introduced. Made of quality natural leather and available in brown and black, it is an ideal complement to the sleek designs of all the RX100 series cameras including the new RX100 IV model.
