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 NEX-F3 test data on DxO MarkGreat image quality; Above-average battery life for a mirrorless camera; Makes light work of shooting self-portraits; Very versatile video mode for a camera of this class.
Built-in flash is weak and uneven; Grip feels cramped due to low shutter button position; Bundled kit lens turns in a mediocre performance, and body isn't sold without the lens.
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.
