Now, it’s easier to capture more stunning stills and movies at every opportunity. The new RX10 IV is much more than a solid, smart all-in-one compact — it packs enough groundbreaking innovations for even professionals to marvel at, from ultra-fast AF system of its kind, to legendary optics throughout its 25x zoom range, to extraordinarily precise, powerful image processing, and more.
24-600mm11 F2.4-4 large-aperture optical zoom lens
This 25x optical zoom lens features remarkable 24-600mm11 extra-wide-angle-to-ultra-telephoto range plus macro capability, AA (advanced aspherical) and ED (Extra-low Dispersion) glass elements, ZEISS® T* Coating, and large F2.4-4 aperture. These help the camera to provide high optical performance for high resolution and beautiful bokeh.
Exmor RS™ CMOS sensor for speed
315-point focal-plane phase-detection AF provides for extraordinarily fast, precise autofocusing and tracking. Furthermore, the 20.1 MP (effective) 1.0-type stacked CMOS image sensor with DRAM chip enables up to 960 fps12 super-slow-motion shooting13 and up to 1/32000 sec. super-high-speed anti-distortion shutter.
High-speed BIONZ X image processing engine
Achieving higher-speed processing performance than its predecessor, the new BIONZ X image processing engine is remarkably reliable at capturing fast-moving subjects and continuous shooting of up to 24fps14. Its newly developed image-processing algorithm lets you capture high-quality images with less noise all across the sensitivity range while maintaining natural details.
Wide high-density 315-AF-point coverage
The world’s most focal-plane phase-detection AF points (315) cover approx. 65% of the entire image area of the RX10 IV’s new image sensor. This makes AF coverage widespread and dense enough to quickly capture subjects, such as small or fast-moving ones that are otherwise difficult to focus on, throughout the image area.

High-density Tracking AF Technology
Tracking performance is highly reliable, as the RX10 IV is the first Cyber-shot camera with High-density Tracking AF Technology that activates AF points to cover the area around a subject with outstanding precision and stability.

Super slow motion13 up to 40x slower than natural motion
The stacked CMOS sensor enables shooting at an extra-high frame rate up to 960fps12 (40x slower than natural motion) for extended maximum durations (up to 4 seconds in Quality Priority mode and up to 7 seconds in Shoot Time Priority mode) all the way up to ultra-telephoto range. As a result, you can capture exceptionally clear, smooth close-ups of faraway action in super slow motion detail.
One-touch remote/ One-touch sharing
One-touch remote makes your smartphone or tablet a viewfinder/remote control. One-touch sharing transfers photos/videos to your device for SNS sharing. Just install a PlayMemories Mobile app via Wi-Fi to your NFC-enabled Android device, then touch the device to the camera to connect them. No NFC? No problem, as new QR code compatibility can also pair the devices.
