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.

Cameras 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
Good (modern, not retro!) looks and solid build; f/1.4 Schneider-Kreuznach lens starting at a wide 24mm equivalent with excellent low-light capabilities; Advanced photographic controls and RAW capture; 3-inch, articulated AMOLED monitor.
Limited telephoto reach; Inconsistent and disappointing JPEG images; Some corner blurring at both wide and tele; Noise suppression too strong at ISO 800 and above, robbing detail.
Fast lens; Sharp lens; Rock-solid image stabilization; Fast autofocus and shutter lag; Level gauge.
Sluggish startup; Battery life lower; Switches can change accidentally; Slow buffer clearing.
