Two things mate -
a) great to see you also have great taste in new cameras :-)
b) my experiments with the exr side of things do not seem to show a huge difference - am I missing something? ... or is it more subtle to the eye?
If you are finding success with exr mode, could you perhaps post 2 pics, 1-with exr, 1- without and let me see the difference
I'll do the same with something from my end too
