Are we there yet? While all the companies seem to be working on some phase-like AF system to add to contrast, I don't get the feeling they're very close to the revolution yet.

 

I think the problem is to expect Canon 1D or Nikon D3/4 level of tracking performances from tiny mirrorless cameras. To be completely fair, the 40D was, IMHO, quite poor at tracking (still better much than an OM-D though) and judging by how many cameras still rely on "canon like diamond shaped full of gaps AF zones" or "nikon like only in the center super dense array of zones", I think mirrorless cameras are going to get to this level or are possibly there already. 

 

What is misleading too is that Contrast AF has almost enabled full area scanning while phase will rely on a smaller amount of spots, IMHO.

 

The X100S has had positive -very early- reports so far and weren't the Nikon's J/V1 said to be good at tracking ?
