I have been doing a few tests with the 1DX mark ii and I have to say that the DPAF is unreal. I set up a shot in almost darkness (where I had issues seeing myself) to test out the noise at ISO 51000. I was able to achieve focus with the center focus point (the most sensitive one) fairly easily, but at at times it did hunt a little. However, when I switched to live view not only did the still life become easier to see with the exposure simulated screen, I was able to focus anywhere instantly, and I mean instantly and accurately. To get an idea of how dark it was, a shot that was still a little underexposed was ISO 51,000 f/2.8 and 1/30, much darker than I will ever experience at a wedding. I am blown away at how crazy fast and accurate this DPAF is. I wish I could find a way to use it more in my shooting style. Anyone else finding the same thing?
