Maximum effective ISO is an estimate of the highest sensitivity at which a camera can capture excellent quality photos.
Cameras with higher effective ISO will be better choices for indoor photography, night shooting, and indoor sports photography, especially if you intend to make large prints.

NX300 test data on DxO Mark NX20 test data on DxO MarkHigh quality images with lots of detail; Excellent graphical user interface is fun to use; Smart implementation of WiFi makes it relatively easy to share photos wirelessly.
Designed so much like a DSLR you may wonder why you shouldn't get a DSLR instead; Some performance issues, particularly slow buffer clearing and shot-to-shot speed; Initial WiFi set-up can be confusing.
Stylish "retro modern" design in two color schemes; attractive 3.3-inch AMOLED tilting touchscreen; new APS-C CMOS sensor with on-chip phase detection AF; better image quality, particularly in low light at high ISOs; faster all-around performance; improved Wi-Fi connectivity.
Camera feels more plasticky than expected when you pick it up; slower shot-to-speeds compared to rivals; poor buffer depth with raw files; aggressive anti-noise processing destroys detail in high ISO shots; display smudges easily and is rather dim; no EVF support.
