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
Head-turning (funky, but cool) design and solid build; 8x optical zoom lens with 28-224m-equivalent reach; Built-in Wi-Fi for easy image sharing (Facebook Ready version posts directly to the social site); Full HD 1080p video at 24fps.
Unintuitive (almost clumsy) physical controls; Inconsistent exposure and decision-making in Auto mode; Image quality not that much better than good smartphone cameras; Poor battery life (just 200 shots); Only uses microSD cards; Weak LED flash.
