Together with launching a new member of the Alpha series, the revolutionary MILC Sony Alpha a7R II, the Japanese giant Sony pushed back the frontier in its RX series as well by introducing superb Sony RX100 IV and Sony RX10 II, which add a new dimension to the world of prosumer compacts with their video characteristics.
Just a little more than a year after the popular Sony RX100 III was introduced, a successor arrives - Sony DSC-RX100 IV. This tiny prosumer will preserve the reputation of the Sony RX100 models, which has been earned by packing a large sensor into a small camera body, bearing in mind that the new model is equipped with Sony’s next generation sensor - a 20.1MP 1"-type Exmor RS CMOS sensor. The label Exmor RS indicates that the sensor is stacked, which is to say that it features such design that its photosensitive regions are separated into different layers from the supporting circuitry, thus allowing more space for the light sensitive portion of each pixel. Moreover, there is a DRAM memory chip, which in combination with the sensor brings high speed of processing information - more than 5x faster readout of image data in relation to the predecessor. This combination of the said sensor and chip, along with a BIONZ X processor, brings astonishing results when shooting fast-moving subjects, as well as magnificent 16 fps continuous shooting.
With such an internal structure, speed is one of the chief virtues of the new RX100 IV, so such fast readout of image data on the part of the sensor brings very great speed of the shutter (1/32000s) without unwanted vibrations (Anti-Distortion Shutter), which enables this prosumer compact to catch crystal clear images with a wide open aperture, even in low light and even when a subject is moving uncontrollably fast (there is also an upgraded Fast Intelligent AF system, which detects a moving subject in as little as 0.09 seconds with remarkable accuracy). This configuration also brings super slow motion video, at up to 40x slower than the standard rate, but not in 4K, yet at 960 fps, 480 fps, or 240 fps.
4K resolution (3840 x 2160 at 30 fps) is available in the standard video mode, and it is the same as in the case of the Sony a7R II. What is also the same like in the case of this Alpha interchangeable-lens camera, there is no pixel binning, so all the fine details of 4K video are captured with minimum moire and 'jaggies'. Video recording takes place through the use of the XAVC S codec, at a bit rate of 100 Mbps during 4K recording and 50 Mbps during Full HD shooting. However, 4K video shooting is limited to only 5 minutes per film.
The Sony RX100 IV kept the same ZEISS® Vario-Sonnar T* 24-70mm f/1.8-2.8 lens as the Sony RX100 III, and the overall appearance of the camera did not change much. Framing is carried out through a tilting 3" 1,228,800-dot WhiteMagic TFT LCD screen, or a pop-up 2,359,296-dot electronic XGA OLED Tru-Finder with 0.59x magnification. Above all, the RX100 IV boasts built-in Wi-Fi with NFC, which brings easy connection to smart devices, and fast transfer of data.
As far as the other innovation from the RX line-up, Sony DSC-RX10 II, is concerned, it is significantly enhanced in relation to the predecessor Sony RX10, which was announced more than a year and a half ago, and it has a number of features in common with the Sony RX100 IV. Like the RX100 IV, the RX10 II is equipped with a revolutionary stacked 20.2MP 1"-type Exmor RS CMOS, with photosensitive regions separated into different layers from the supporting circuitry, thus allowing more space for the light sensitive portion of each pixel. Once again, there are a DRAM memory chip and BIONZ X processor, which in combination with the sensor bring high speed of processing information (more than 5x faster readout of image data in relation to the predecessor), but the continuous shooting rate is now slightly lower in comparison to the RX100 IV - 14 fps.
The shutter is also Anti-Distortion Shutter with the speed of 1/32000s, once again we have an upgraded Fast Intelligent AF system, which detects a moving subject in as little as 0.09 seconds with remarkable accuracy, as well as super slow motion video, at up to 40x slower than the standard rate, but not in 4K, yet at 960 fps, 480 fps, or 240 fps.
The Sony RX10 II sports the same video mode as the new Sony RX100 IV and Sony A7R II (3840 x 2160 at 30 fps), and once again there is no pixel binning, so all the fine details of 4K video are captured with minimum moire and 'jaggies'. Video recording also takes place through the use of the XAVC S codec (the same as in the case of the Sony RX10), at a bit rate of 100 Mbps during 4K recording and 50 Mbps during Full HD shooting. However, what places the professionally styled RX10 II above the pocket-friendly RX100 IV is the length of 4K video - up to 29 minutes, in relation to only 5 in the case of the RX100 IV.
Like the RX100 IV, the Sony RX10 II, too, is characterized by very similar design in relation to its predecessor, and it is equipped with the same lens as the RX10 - ZEISS® Vario-Sonnar T* 24-200mm f/2.8 - which is to a certain degree better than the RX100 IV. The LCD screen and viewfinder are also the same like on the RX100 IV (only the viewfinder is now not pop-up, and its magnification is somewhat greater - 0.70x), there is also built-in Wi-Fi with NFC for fast data transfer to compatible devices, while what distinguishes the RX10 II is the fact that it is environmentally sealed, and resistant to dust and moisture.
The ultra-fast Sony RX100 IV and Sony RX10 II will come onto the market next month, priced at $1000 and $1300, respectively. Pre-sales for each model start on June 17th.
