I had my first session using the 1D X Mark II today. I've been using 1Ds Mark III and 1Ds Mark II cameras for years, so most of the controls were exactly where I expected them. I was using the 85L 1.2 lens on it and only saw one out-of-focus image from the 200 or so I took, which is incredible...simply incredible. I've lost so many images over the years to that lens simply not finding crisp focus on a 1Ds Mark III. It was refreshing to see eyelashes every single time (except for the one).
One thing I'm going to have to figure out is how to set the metering to only sample a tiny bit of the frame. I was having a little trouble getting the exposure right from time to time when I'd have 3 different light sources, and the camera wanted to talk about the brightest one, regardless of whether it was on the face or not. I'll have to actually open the manual.
All-in-all, I was giddy to use it, which I really haven't been about any camera since I got my first 1Ds Mark II. Everything else has been a "good tool", but this was something a little different.
