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.

T3i test data on DxO Mark GF5 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
Excellent image quality; Good grip; Full HD video recording; Swiveling LCD; Very fast autofocus; HDMI output.
Slow frame rate for sports shooting; Tendency to overexpose in bright sunlight; Live View AF is slow; No microfocus adjustment.
Small body pairs nicely with compact, retractable Power Zoom lens. Extremely fast autofocus. Worthwhile improvements in image quality. Touchscreen overlays can now be hidden.
LCD panel is prone to fingerprint smudges. Weak flash, and no hot shoe. Modest burst performance, and very limited buffer for raw shooting. Noise levels and dynamic range still lag competition.
