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.

Q test data on DxO Mark S100 test data on DxO MarkThe first genuinely compact--almost pocket-friendly--compact system camera, paired with equally small, interchangeable lenses. Great ergonomics for the size, and it feels like a real camera, not a computer with a lens.
Very restrictive lens selection at launch. All but two current lenses have severe limitations in functionality. Performance is sluggish, and image quality trails large-sensor cameras by some distance.
Slimmer than past models; 12-megapixel resolution sensor improves on image quality across ISO range; Video includes 1080p, autofocus, and zoom during recording; HDR mode works well.
Costs $30 more; Slight buzz when zooming while recording video; Grip isn't as useful as it could be; Slow autofocus.
