I know there is another thread going re flash on an OMD but I have a different question and didn't want to semi-hijack the other thread.

I use flash a lot - quite often outdoors in bright light. My one "complaint" about the OMD in terms of possibly buying one is that it has no on-board flash. However, my use of the EP3 and its flash demonstrates that the Oly/EP3 flash software/firmware is nowhere close to Nikon's DSLRs as far as the ability to virtually automatically deliver excellent flash/avail light balance.

So SINCE the EP3s flash work is one of the weak points IMO, I was wondering if anyone here can offer an opinion comparing the Nikon DSLR flash implementation with the OMD/add-on flash. IOW, does anyone who routinely uses flash feels the OMD matches their previous experience with Nikon DSLRs as far as the balance/appearance/ease of use when using flash?
