Dynamic Range
As you can see from the Dynamic Range chart, the E-M5 Mark II does well in our Applied Imaging tests, registering an impressive 12.5EV at ISO 100. It holds up OK to ISO 400 but thereafter drops off quite quickly, indicating that shadow noise will becomes increasingly visible. At ISO 1600 we still see a respectable 9.2 EV, and ISO 3200 gives a just-about-acceptable 8.1 EV. But the top three ISO settings all show very low figures, suggesting that detail will be swamped by noise, especially in the shadow regions.
