Re: Is the OMD-EM1 a replacement for the E5 or the OMD-EM5?

It's all subjective and relative. The E-M1 can focus well with Four Thirds lenses in very low light - dark enough for the view through an E-5's optical reflex viewfinder to be very dim indeed. But, yes, my experience is that the an E-5 will continue to focus after the E-M1 gives up as the light gets dimmer. Is it a deal-breaker? - not at all. Micro Four Thirds lenses on the EM-1 focus in even darker light than an E-5. You also have the benefit of the EVF which works well after an optical finder becomes useless so you can manually focus in ridiculously dark conditions with the E-M1.

Is Olympus confident that the E-M1 is better than the E5 for BIF and panning at say motor cycle racing?
Olympus in Japan tell me that their own field tests indicate the E-M1 is better than an E-5 in C-AF for applications like BIF. I am not a BIF expert but Andy Elliot, who is, and uses an E-5, is so far impressed with his limited time on my own E-M1 using his lenses. Panning and motorcycle racing - I haven't tried this and some are not optimistic because of the EVF freezing in C-AF mode, but Olympus tells me that this is not so different from optical viewfinder blanking as the mirror flaps. We'll find out the truth as more people use the camera for things like panning.

There is little firm data to support whether there is a real improvement for C-AF on M4/3 lenses, particularly with the lack of cross-type PDAF points.
Of this there is absolutely no doubt - C-AF with Micro Four Thirds lenses until now was pretty hopeless unless the subject was fairly still in the frame. BIF, for example was almost impossible. PDAF in C-AF mode with MFT lenses is hugely superior.

The lack of cross type AF points is only a problem if you are focusing on regular horizontal detail, like venetian blinds. It is not a problem if you have amorphous details and that's mostly what you have with nature photography, for example.

Is anyone prepared to say if the E-M1 is anywhere near as good as an entry level DSLR, or comparable to say a D7100, for BIF or action photography in general?
The word I had from Akira Watanabe at Olympus in Japan is that their field tests showed the C-AF performance was similar to a Nikon D7100.
