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.
Shoot beyond human vision.
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 motion, super-high-speed 1/32000 sec. Anti-Distortion Shutter, and handy 4K movies. Now explore infinite imaging freedom beyond imagination.
1.0-type stacked CMOS sensor with DRAM chip
Heart of super-high-speed shooting
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.
Stacked structure with DRAM chip (memory) attached
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 caused by the rolling shutter phenomenon.
Free your imagination.
View life anew at 40x super slow motion.
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 motion 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.
