Sony RX100 IV and RX10 II Boast Stacked Sensors and 4K Video
![]()
In addition to unleashing the monster that is the a7R II, Sony today also announced two new cameras for its Cyber-shot RX lineup. The RX100 IV and RX10 II are new followup cameras that feature fresh technological innovations; both cameras boast stacked 1-inch sensors and 4K video recording.



Both cameras offer 40x super slow motion video capture. Users can choose frame rates of 960 (at 1280×800), 480 (at 720p), and 240 fps (at 1080p). A “start trigger” feature lets you start a video 2 to 4 seconds before you actually press the trigger, capturing a moment that just happened as a slow motion video (2 seconds at 960fps takes 80 seconds to play back at 24fps).
The stacked sensor also allows for a rapid continuous shooting speed of 16fps on the RX100 IV and 14fps on the RX10 II. The high-speed anti-distortion shutter enables sharp photos while shooting wide open and minimizes the rolling shutter effect other cameras are plagued by.
There’s a high-speed autofocus system in both cameras that uses contrast detection to lock onto moving subjects in as little as 0.09 seconds.



The front of the RX100 IV has a 24-70mm (35mm equiv.) f/1.8-2.8 lens, while the RX10 II has a 24-200mm (35mm equiv.) f/2.8 lens. Both cameras feature a 2.35-million-dot electronic OLED viewfinder (the RX100 IV has a pop-up viewfinder).
For video recording, the cameras can shoot 4K video. The pro-oriented RX 10 II can capture 29 minutes at a time, while the consumer-oriented RX100 IV is limited to about 5 minutes for each clip. Both cameras offer Picture Profile, S-Log2/S-Gamut, and photo capture during 4K recording.
Finally, both cameras offer Wi-Fi and NFC connectivity for wireless data transfers.
The RX100 IV and RX10 II will be available starting in July 2015 for $1,000 and $1,300, respectively.
