As to moving subjects you need to be more specific. Moving as in a sprinter charging the camera is one thing. Your kid or dog running around the room or yard is another. Having shot both I actually now find m43 to be much better for shallow DoF shooting of kids. As much as I\'ve personally mocked face-detect over the years now for shallow DoF I\'m finding face detect AF on the E-M5 to have a way higher keeper rate than any PDAF C-AF system. The E-M5 system detects the eyes and you can even select for left, right or closest eye for focus. It seems like a gimmick until you use it compared to a PDAF system with fixed AF sensors. Of course a skilled shooter with either system is going to do way better than a spray and pray shooter on either.
Right now the CDAF systems on the m43 cameras are faster in S-AF than all the Canon DSLRs and their kit lenses and even trumping some of the USM L lenses simply because everything is up against the mass of the focus group these days and the m43 lenses are designed with very low mass groups (like the STM lenses from Canon are doing). Which is shocking given how wickedly bad CDAF was in the not very distant past.
I was going to write the exact same thing. Last year some friends asked me to shoot some baby photos. I took a 5DM3, D800, and a OM-D. I was expecting to use the situation to compare the AF performance of the 5DM3/D800 but after 10 shots with each I realized neither body could AF fast enough for this not-so-fast moving baby. Lighting was f/1.4 1/160 ISO 3200 mixed tungsten and both DSLRs took 3-4 seconds to lock every time. I took out the OM-D with the Pany 25mm f/1.4 and it locked focus within 1 second every shot. And even though it was close-quarter shooting I could still get adequate DOF on the OM-D @ f/1.4 whereas I\'d have to stop down to f/2.8 to get the same DOF on the FF bodies, meaning in this situation the FF sensors provided zero advantage over the OM-D in terms of noise.
To everyone who hasn\'t tried a current-generation Olympus or Panaonsic m4/3, I think you\'re doing yourself a disservice. Many think these cameras are compromises in AF performance when in fact they\'re better than DSLRs in some situations.
How fast the AF is (at least with the 5D3) depends mostly on what lens you use.
And you could get both thin DOF and larger DOF with the DSLR cameras. But with the Pany you couldn\'t choose...........
