Sony is in New York City, where it just announced another Cyber-shot RX10-branded camera.

Called the RX10 IV, it packs the "world’s fastest" AF lock speed of just 0.03sec, according to Sony, as well as offers 24fps continuous shooting with full AF/AE tracking for up to 249 frames. Other features include a 24-600mmiv F2.4-F4 ZEISS Vario-Sonnar T lens for a wide focal range, an OLED viewfinder, and a 315-point phase-detection AF system that'll give other interchangeable lens cameras a run for their money.

It uses Sony's 1.0-type 20.1-megapixe Exmor RS CMOS stacked image sensor with DRAM chip, as well as Sony’s Bionz X image processor and front-end LSI. The new RX10 IV can be used for 4K (QFHD 3840 x 2160) movie recording. In 4K mode, Sony said the RX10 IV "utilises full pixel readout without pixel binning, capturing approximately 1.7x more information than is required for 4K movie output".

You have the option of shooting at either 24p or 30p in 4K mode (100 Mbps), or in frame rates of up to 120p in Full HD mode. Super slow motion video recording is also available, with 1000fps, 500fps, and 250fps options. And finally, the RX10 IV is dust and moisture resistant, and it is Wi-Fi, NFC, and Bluetooth compatible. If any of that interests you, the camera will be available from October.

It has a price tag of £1,800/$1,700.
