Review Excerpt

  • Extremely fast autofocus; Pop-up flash and AF-assist lamp; Full HD recording; wisely limited focus for touchscreen; excellent print quality results; removable grip.

  • Larger than some competitors (see E-PL3 if you prefer a smaller camera); strong noise suppression; touchscreen easily activated by mistake; list of options is overwhelming; shoulder strap D-rings are noisy.
