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
Exceptionally detailed and uniquely beautiful image quality at low ISOs; Fast, sharp 28mm-equivalent lens; Simple, straightforward controls match camera's simple, straightforward (street photography) goals.
Fixed-focal-length lens; Image quality deteriorates significantly at ISO 800 and above; Overall sluggish performer; Falls short when capturing JPEGs; Terrible VGA-only video quality; Very poor battery life; No built-in flash.
Excellent 5-axis sensor-shift image stabilization; Sensor-shift IS brings stabilization to nearly any lens; Much-improved ergonomics and top-deck control layout; 'Mark II' maintains same impressive image quality, dynamic range and high ISO performance; XAVC S 50Mbps video format; Faster start-up time; Hybrid AF performs well with good continuous AF.
(Similar to A7): Loud shutter (but electronic first-curtain helps); Battery life could be better; Low-light AF still not as good as most DSLRs; High ISO JPEGs look over-processed; Slow buffer clearing; Limited selection of native Sony FE lenses (but it's getting better).
