For the E-M5, you are better off increasing ISO in camera than increasing in post, subject to a few conditions. See for example http://forums.dpreview.com/forums/thread/3352455 From what I've read, this would not be true for current Nikon DSLRs.
I don't see where you got that idea. Look:
http://www.sensorgen.info/OlympusOM-D_E-M5.html
Shooting at ISO=800 vs. ISO=400 you lose a full 0.60 EV in Dynamic Range while at the same time losing a full 1.04 EV in available highlight headroom. At that point, why would one bother (simply to be able to increase Shutter Speed by 0.88 "stop") ?
Knowing this seems more valuable for an E-M5 user than knowing whether "exposure" includes ISO.
Why is it better to know how to decrease Dynamic Range than to increase Signal/Noise Ratio ?
I like technical information, both for its own sake and to aid in taking pictures. Problems arise when technical info is used to play gotcha games.
I think when other people know more than oneself, they should be gratefully thanked for assisting.
