World’s Fastest1 AF acquisition speed of 0.03 sec. 2

The RX10IV features the world’s fastest1 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 seconds2. Subjects can be tracked and captured with precise detail and clarity within the extensive 24-600mm3 range.

Incredible Exmor RS stacked CMOS sensor

This 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 24fps4 continuous shooting up to 249 frames5 with AF/AE tracking, blazingly fast shutter speed of up to 1/32000 sec., breathtaking 4k6 movie and super slow-motion HFR7 (High Frame Rate) movie clip recording of up to 960fps (40x), not to mention remarkable low-light low-noise capability.

ZEISS Vario-Sonnar T* 24-600mm3 ultra-zoom lens

The astonishing 24-600mm3 ZEISS Vario-Sonnar T* lens features a large maximum aperture of F2.4-F4.0, helping it achieve outstanding image quality throughout the entire ultra-telephoto zoom range. Eight ED (extra-low dispersion) glass elements including two ED aspherical and one Super ED lenses compensate for the chromatic aberration while the ZEISS T* Coating helps reduce flare and ghosting. This incredible lens also features built-in Optical SteadyShot image stabilization and a minimum focusing distance of 2.36 ft. with 0.49x maximum magnification for tele-macro photography.

24 fps4 up to 249 frames5 with AF/AE tracking

Designed to allow for high resolution, continuous shooting at high frame rates, the RX10 IV features a BIONZ X image processing engine with front-end LSI that achieves high-speed continuous shooting of 20.1-megapixel images at up to 24 fps4 with full AF/AE tracking, and an impressive buffer limit of up to 249 images5. With the significant improvements in processing power for the RX10 IV, EVF display lag during continuous shooting has been substantially reduced, allowing you to capture the decisive moment with ultimate confidence. Also, for convenience during image playback, continuously shot images can be displayed in groups instead of individual shots.

4K6 movie w/ direct pixel readout, no pixel binning and fast AF

RX10 IV offers the advantages of 4K6 (QFHD 3840 x 2160) movie recording, with its Fast Hybrid AF system, realizing fast and accurate focusing speed and AF tracking for video. In 4K6 mode, the new RX10 IV utilizes full pixel readout without pixel binning, capturing approximately 1.7x more information than is required for 4K6 movie output ensuring that all the finest details are captured accurately. Utilizing the XAVC S9 codec to record video at a high data rates, users have the option of shooting at either 24p or 30p in 4K6 mode up to 100mpbs, or in frame rates of up to 120p in Full HD mode.

Super-speed Anti-Distortion Shutter

The super-speed Anti-Distortion Shutter has a maximum shutter speed of up to 1/32000 second, which minimizes the “rolling shutter” effect commonly experienced with fast moving subjects. This blazingly fast shutter speed also allows the camera to capture sharp, crystal clear images with a wide open aperture in bright conditions. Shooting at wide aperture with fast shutter speed allows photographers and videographers to capture beautiful content with sharply focused subjects and defocused backgrounds under some of the most difficult, bright lighting conditions.

High-density Tracking AF technology.

For the first time on a RX-series camera, advanced high-density tracking AF technology - which had only been previously available in a select few of Sony’s acclaimed line of α interchangeable lens cameras - concentrates AF points around a subject to improve tracking and focus accuracy, allowing even the most unpredictable subjects including fast-moving athletes and birds in flight to be captured with ease.

Optical SteadyShot image stabilization

The built-in Optical SteadyShot image stabilization helps to reduce image blur caused from camera shake, equivalent to approximate 4.5 stops shutter speed improvement, which is especially handy at high magnification when the lens is fully extended to 600mm, but equally as good throughout the entire zoom range.

Tele-macro up to 600mm3 as close as 2.36 ft.

With a minimum focusing distance of 2.36 ft (72 cm) and 0.49x maximum magnification at a fully extended 600mm3, the ZEISS Vario-Sonnar T* 24-600mm3 F2.4-F4.0 lens is capable of producing amazingly detailed tele-macro images.

Super slow-motion movie HFR7 (High frame rate)

See the unseen with super slow-motion HFR7 (High Frame Rate). The RX10 IV can capture super slow motion movie clips at up to 40x slower than real time. You can chose from 960fps, 480fps or 240fps4 capture rates to playback at 1920 x 1080, in either 60p, 30p or 24p. Choose between 'quality priority' (4 sec. recording) and 'shoot time priority' (7 sec. recording). There’s also an option to set 'start trigger', 'end trigger' or 'end trigger half”'which will start capturing movie before, after or before and after you press the movie rec. button so you can time those split-second moments perfectly.

Designed for a pro-video workflow

The RX10 IV has a variety of including Picture Profile, S-Log3/S-Gamut3, Gamma Display Assist, Proxy recording, Time Code / User Bit and more, as well as input for external microphone via MI (multi-interface) shoe or mic jack and output for headphone monitoring. Focus and exposure can be monitored for fine control with peaking function and zebra respectfully. You also have the choice of region setting between NTSC and PAL movie frame rates.
