Sony RX10 IV confirmed

Sony has expanded its RX10 line of superzoom compacts with the flagship RX10 IV.

The RX10 IV arrives almost a year-and-a-half after the RX10 III. Sony claims the camera has the world's fastest AF time of 0.03sec (among fixed-lens cameras equipped with 1in sensors).

Sony RX10 IV specs

  • 20.1MP 1in sensor
  • BIONZ X processing engine
  • 24-600mm f/2.4-4 lens
  • 315-point phase-detect, 25-point contrast-detect AF system
  • 24fps burst shooting with AE/AF tracking (for up to 249 images)
  • 3in, 1.44million-dot tilting screen
  • 2.35million-dot OLED viewfinder
  • Electronic shutter up to 1/32,000sec
  • Dust- and moisture-resistant body
  • Wi-Fi, NFC and Bluetooth

The new camera features an AF system that combines 315 phase-detect AF points with 25 contrast-detect points, and this covers around 65% of the frame.

With this, Sony claims the camera is able to continue to focus on moving subjects and maintain auto-exposure, even when shooting at 24fps.

Sony also credits this to High-density Tracking AF Technology, something it has also included in its previous A6300 and A6500 compact system cameras. A range of additional focusing technologies, such as Touchpad AF and Eye AF, are also on hand, as is a focus-limit switch on the lens barrel.

The RX10 IV also sports a 24-600mm f/2.4-4 lens, which appears to be the very same optic as on the previous RX10 III, and this has Sony's Optical Steadyshot system built into it. 

The camera also uses a 1in-type 20.1 MP Exmor RS CMOS stacked image sensor with its own DRAM chip, and a BIONZ X image processor with a front-end LSI.

As we expect from Sony, the camera offers 4K video recording. Like the RX100 V, it manages to record at a 4K UHD (3840 x 2160pixel) resolution without pixel binning.

The camera also offers an anti-distortion electronic shutter that allows it to shoot silently at shutter speeds up to 1/32,000sec. 

Other features include a 3in tilting LCD screen, a high-resolution OLED viewfinder and the Wi-Fi, NFC and Bluetooth triplet of wireless technologies. 

Sony RX10 IV price and release date

The Sony RX10 IV will be available for £1800 in the UK and $2000 in the US, and it will be available from October.
