For a recent outback trip I got an FZ1000 as a walk-around camera as the same old story applies to me as well, the Pentax K3 and tele lenses are getting to be a burden. And I was blown away by the speed of the AF on the Lumix. A smudge in the sky in the viewfinder would get an almost instant lock, while the DSLR would very often hunt and the shot get lost. So I'm looking to move to an MFT kit assuming Panasonic or Olympus can perform as well in this format. Reasonable assumption? Panasonic are offering CDAF with Depth from Defocus - the same as on the FZ1000 I believe. The 4K photo modes are attractive - I can live with 8MP files - but one review I read said that its CAF wasn't up to the 30 FPS rate when tracking birds. Of course the new EM1 has all the fruit salad for good tracking CAF. So it's the obvious choice, when it comes out? What does the brains trust think?
