Sony RX100 IV and Sony RX10 II

Sony recently launched the Sony RX100 IV and the Sony RX10 II to the Cyber-shot RX family series and I had the opportunity to have a look and a short hands on experience with the new functions and capabilities of the Sony RX100 IV and Sony RX10 II.

I would like to share with my readers and followers more information and details of the new Sony RX100 IV and Sony RX10 II from the press release by Sony –

The two new models feature the world’s first 1.0 type stacked Exmor RS™ CMOS sensor[1] 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 five times the readout rate of image data[2] and are responsible for a variety of standout features that have previously only been available in selected professional-level video cameras. These impressive capabilities include 40x super slow motion video capture at up to 960fps[3], an ultra-fast Anti-Distortion Shutter with a maximum speed of 1/32000 second, high-resolution 4K movie shooting[4] and more.

RX Series Lineup

“Utilising Sony’s decades of expertise in digital imaging, we’ve made it possible for everyday customers to enjoy a professional imaging experience with the new RX100 IV and RX10 II cameras. With the power of the world’s first 1.0-type Stacked CMOS sensor packed into a compact, portable body, these new cameras bring the excitement and creativity of high frame rate shooting, 4K recording and a variety of other pro-quality features to a whole new audience.” said Kimio Maki, Senior General Manager of Digital Imaging Business Group for Sony Corporation.

Dai Tanaka, General Manager, Digital Imaging Division, Sony Electronics Asia Pacific added, “The new RX100 IV and RX10 II models make a strong statement for Sony, as they break through all existing boundaries of compact cameras, and will allow professionals, hobbyists and enthusiasts to capture images and videos that they never before thought were possible.”

Up to 40x 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 videos of up to 40x 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 960/1000fps, 480/500fps and 240/250fps frame rates and among 60p/50p, 30p/25p and 24p playback formats4 to optimise the recording to fit the speed of the moving subject. They also have the option to use the movie record button as a ‘start trigger’ to begin recording once the 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[5] before the movie button is pressed, enabling shooters to capture the decisive moment with much more consistency and accuracy.

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. In particular, its fast processing capability results in continuous speeds of up to 16fps on the RX100 IV, and up to 14fps 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 allows the new cameras to capture sharp, crystal clear images with a wide open aperture at brightness levels up to EV19[6]. 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.

RX100 IV

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 recording5. 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 the use of the XAVC S codec, which records video at a high data rate of 100Mbps during 4K recording and 50Mbps during full HD shooting5.

The capacity for shooting 4K differs slightly on each of the two cameras, as the more professionally-styled RX10 II can shoot 4K videos at extended lengths of up to 29 minutes, while the more casual, pocket-friendly RX100 IV can shoot 4K clips of up to approximately five minutes in length. Furthermore, professional caliber 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-megapixel 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 has the same body design as the original RX10 and feature a ZEISS® Vario-Sonnar T* 24-200mm (35mm equivalent) F2.8 lens.

Each of the camera 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 continues to have the convenient retractable EVF with ZEISS® T* coating from the RX100 III model that debuted last year.

Both 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[7]. 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 has the ability to access Sony’s growing range of PlayMemories Camera Applications. More information can be found here:

Aesthetically, both of the new models feature a variety of customisable controls and buttons to fit the style of any shooters. The RX10 II further adds dust and moisture resistance.

A new stylish soft carrying case, LCS-RXG has also been introduced. Made of quality natural leather and available in brown and black colors, it is an ideal complement to the sleek designs of all the RX100 series cameras including the new RX100 IV model.
