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
Excellent image quality for its class; Very good optical performance from the bright f/2-2.8 4x lens; Quick autofocus, even in very low light; Fast burst modes; EVF fixes the flaws of optical viewfinder in X20; Tilting high-res LCD screen; Excellent feel in the hands; Very good battery life.
Top shutter speed is only 1/1000s when lens is wide open; No built-in ND filter; 28mm eq. may not be wide enough for some; Shallow buffer depths; Default NR processing a bit heavy-handed.
Very good image quality; Great performance in most respects; Bright zoom lens with good macro performance; Photographer-friendly body easily fits in a coat pocket or small bag; Roomy, high-res built-in viewfinder; Decent battery life
Won't fit in a pants pocket; Relatively low resolution by modern standards; Zoom lens has only a modest telephoto; Soft corners at wide or tele positions; Aperture dial is too easily bumped; Bundled flash is fairly weak
