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
Handsome retro styling; Very good image quality and dynamic range, with competitive high ISO performance; Lightning fast autofocusing; Excellent burst speeds (nearly 10fps at full res); Top shutter speed of 1/8000 second; Sharp, bright 17mm f/1.8 kit lens; 3-inch tilting touchscreen LCD with 1.04M dots of resolution.
Heavier than some mirrorless models; Weak flash; Below average battery life; No built-in viewfinder (but EVF available in a kit or for separate purchase); A bit pricey compared to the similar E-M5, which offers a built-in EVF and weather sealing at about the same price.
Huge bang for the buck; Great image quality; Excellent high ISO performance; Fast autofocus; Good burst frame rate with deep buffer; Pentaprism viewfinder; Twin control dials; Articulated LCD; Comprehensive weather-sealing and freeze-proofing; Unbelievable wealth of rare to unique (yet very useful) features
Wi-Fi wireless communication is slow, clumsy and unintuitive; Video autofocus is prone to hunting or racking focus; Slow buffer clearing; Rather heavy for an entry-level DSLR; Autofocus and metering systems are a bit dated; Below average battery life
