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.
Improved 20.1-megapixel resolution; Impressive image quality, especially for its price; Fast and decisive autofocus (in most conditions); Very good battery life; Good video quality (Full HD 1080p, though it doesn't support 60p frame rate).
Plastic lens mount; Slower burst mode speeds and shallower buffer than A57; LCD no longer fully articulating; Mediocre kit lens; Electronic instead of an optical viewfinder may be a turnoff for some.
