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.
You can learn more at our glossary entry.

NX1 test data on DxO Mark A33 test data on DxO MarkCameras with longer battery life can take more photos before exhausting their batteries.
Special note: The measurement standard for battery life stipulates that if a camera has an internal flash, it must be used for 50% of photos taken. For this reason, comparisons of one camera with an internal flash to another without will not be comparable
Very good, high-resolution image quality; Excellent high ISO performance with RAW files; Very good dynamic range; Blazing fast 15fps full-res burst mode; Deep buffer; Great build quality & comfortable ergonomics; Lots of physical controls; Great battery life; Fast single-shot AF.
Continuous AF performance still not as robust as competing DSLRs; Aggressive JPEG noise reduction at high ISOs; JPEG colors and saturation less pleasing at higher ISOs; H.265 video codec can be difficult to work with.
