Live Composite Mode - allows visual gradual build up of image with multiple exposures as is used in astrophotography - this is similar to Live BULB mode but multiple exposures rather than just one long exposure
adds a cut-down version of the '2×2' control system which is used to great effect on the E-M1
improved HD video:
24Mbps 30p instead of 20Mbps but the
image stabiliser is not as effective and no ability to add an external stereo mic as no accessory port
intervalometer:
nice optional grip (ECG-1) a must have for using larger lenses, it also centres the tripod, and that is all I really need for the E-M5 so very happy with this compromise, and it is even better than the one on the E-M5 in that there is a quick release latch to get access to the battery compartment instead of having to unscrew the whole grip.
