The world of superspeed shooting
Welcome to the awesome new world of super-speed shooting. Super slow motion — once primarily on pro cams. Thrilling fast-action images captured without distortion. Freedom to shoot in bright lighting conditions as never before. Enter the hidden realm of 1/32000-second imagination. Wonders await you.
Super potential. Super reality.
Inside the compact RX100 IV is the world's first1 memory-attached 1.0-type stacked CMOS sensor — a remarkable advance in image shooting possibilities. Use it to reveal the wonders of up to 40x super slow motion2, super-high-speed 1/32000 sec. Anti-Distortion Shutter, and handy 4K movies. Now explore infinite imaging freedom beyond imagination.
World's first1 1.0-type stacked CMOS sensor with DRAM chip
Image sensor breakthrough brings you cutting-edge new functions — including up to 40x super slow motion2 and Anti-Distortion Shutter — that used to be available only with pro-use gear.
Newly developed image sensor design
Stacked under  the pixel area,  Hi-speed signal processing circuit of the new Exmor RS CMOS sensor is extended, and  DRAM chip (memory) is attached to buffer huge image data.
Thanks to the stacked structure and quickly buffering  DRAM chip (memory), the new Exmor RS CMOS sensor realises over 5x faster readout speed4 than conventional models.
Minimised image distortion
Sensor's high readout speed — which enables the Anti-Distortion Shutter — greatly reduces image distortion (photo ) caused by the rolling shutter phenomenon (photo ).
View life anew at 40x super slow motion2.
Catch what unfolds unseen before you. Once primarily on pro cams, extremely high-frame-rate (HFR) movie recording of up to 960fps5 produces super slow motion2 of momentary movements invisible to human eyes. This feature has various settings to suit active subjects, so you can make pro-style movies of a "hidden" universe of movement all around you.
A world of wonder shot at 1/32000 sec.
The super-fast Anti-Distortion Shutter of up to 1/32000 sec. allows you to capture extremely fast motion without image distortion caused by rolling shutter.
1/32000 sec. super-high-speed shutter
The super-fast Anti-Distortion Shutter achieves wide-range shooting coverage up to EV196. You can shoot photos in extremely bright conditions, even with defocused backgrounds.
Up to 16fps7 continuous shooting without blackout
Despite high 20.1 MP8 count, the camera allows fast readout for continuous shooting up to 16fps7 without blackout — catching decisive moments in motion without missing some action.
Give your creative powers free rein.
Enjoy clip 4K — super-real 4K9, 10, 11 movie feature for casual 4K shooting of up to 5 minutes. Pro-grade XAVC S codec10 ensures beautiful footage with high bitrate recording.
Indispensable feature for serious photographers
Retractable XGA OLED Tru-Finder is a standout feature in a camera of this size. Treated with ZEISS® T* Coating, this EVF provides corner-to-corner clear viewing.
Essential gear for unforgettable pictures.
Rather than weighing you down with extras, the new pocket-size RX100 IV gives you the pro-class essentials you need at hand. You're equipped for go-anywhere freedom to capture marvellous moments in memorable images.
