Sony Cyber-shot DSC-RX100 IV Review – Image Quality: Dynamic Range

Dynamic Range

The RX100 IV’s produces a very similar dynamic range to the RX100 III in our Applied Imaging tests. At ISO 100, it offers a very respectable 12.4EV range, providing plenty of scope to extract shadow detail from raw files. Pushing up to ISO 1600 sees the dynamic range drop below 9EV, but it manages to stay above a respectable 8EV at ISO 3200. Pushing up to ISO 6400 and 12,800 sees the figure drop to 7.2EV and 6.6EV respectively as illustrated in our dynamic range chart.
