Sony Cyber-shot DSC-RX100 IV sensor review: Performance stacked in favorBy Kevin Carter - Wednesday August 26 2015 Sensor Review
As the fourth generation of this popular yet premium-priced series of compacts, the RX100 IV has a new “stacked” one-inch-type 20-Mpix Exmor RS BSI sensor as well as some advanced video features, including UHD video and a 960 fps slow-motion recording option. Read on to find out how well the sensor performs in this new upgraded model.
Specifications and Features
Sony’s RX100 series of premium-quality compacts for enthusiasts has proven hugely popular and garnered worldwide acclaim. The RX100 IV is the fourth iteration, and like the model it replaces, has a stabilized Zeiss Vario Sonnar T* 24-70mm (equivalent) f1.8-2.8 zoom and pop-up EVF, but in place of the 1.44m-dot res screen, it has a new 2.35m-dot OLED.
Although the pixel count remains unchanged and the image sensor utilizes the now commonplace back-side illumination, the RX100 IV uses what Sony is calling a “stacked CMOS” design. This new design incorporates recent advances in the supporting electronics with, for instance, on-chip DRAM and shorter-length circuitry, resulting in a physically closer buffer and allowing such features as high bit-rate (up to 100 Mbps), UHD video (albeit with five-minute max clips), and 960 fps slow-motion recording.
Like its predecessor, the RX100 IV has a 3.0-inch, 1.03m-dot multi-angle (tilting) LCD, and built-in Wi-Fi connectivity with NFC.
The Sony RX100 IV measures 4.0 x 2.4 x 1.6” / 10.2 x 6.1 x 4.1cm and weighs 10.51 oz / 298g, body only. It is available now at around $950 (USD).
