Comparing the Specifications of the Olympus E-M10 Mark IV, III, and II

Olympus recently announced a new version of its OM-D, E-M10 camera, the E-M10 Mark IV

For its size, the E-M10s are a very functional camera.  I often use my E-M10 Mark II as a second camera on my nature photography shoots as the E-M10 fits in my jacket or vest pocket.  This is very handy if I’m photographing birds with my E-M1 III and 300 f/4 and I want to take a macro or landscape photograph.

It’s also great if you are going on an outing (dinner, shopping, farm market, etc.) where you can just slide the camera and a small lens like the Olympus 14-42 EZ lens in to your pocket.

Here are some of the biggest upgrades and feature enhancements of the E-M10 Mark IV over the Mark III and Mark II.

  • Upgrade to the TruePIC VIII processor
  • Upgrade from 17MP to 20MP
  • .5 stop improvement in image stabilization
  • Improved Continuous AF using the algorithm from higher end OM-D models
  • A new panning Panorama scene mode (much like the iPhone)
  • USB Charging
