Featuring the world’s fastest AF acquisition time of 0.03 seconds and up to 24 fps continuous shooting with full AF/AE tracking, a 315 point phase-detection AF system as well as an exceptionally versatile 24-600mm F2.4-F4 ZEISS Vario Sonnar T* lens, the new RX10 IV delivers an unmatched combination of mobility and speed for imaging enthusiasts and professionals looking for the ultimate ‘all-in-one’ solution.  World’s Fastest AF acquisition speed of 0.03 sec.The RX10IV features the world’s fastest AF acquisition time thanks to its 1″ Exmor RS stacked back illuminated CMOS sensor w/ DRAM and fast Hybrid AF system that combines the respective advantages of 315 phase-detection AF points – covering approximately 65% of the sensor – and contrast-detection AF to ultimately enable the camera to lock focus in as little as 0.03 seconds . Subjects can be tracked and captured with precise detail and clarity within the extensive 24-600mm range. Incredible Exmor RS stacked CMOS sensorThis large 1″ (1.0-type) back illuminated Exmor RS stacked image sensor with DRAM chip not only enhances efficiency and speed of A/D conversion through its stacked structure due to more circuit sections; it also realizes super-fast readout speed – thanks to a DRAM chip integrated into the sensor structure. Together with the BIONZ X processing engine and front-end LSI, it allows for stunning 20.1-megapixels at up to 24fps continuous shooting up to 249 frames with AF/AE tracking, blazingly fast shu…
