last week-end I got to shoot with the D4s for the first time.
I've been shooting pool pictures in tournaments all around to world for ten years now and I have to say this camera really has it all for the low-light.
The AF was much better both at locking on and at tracking subjects (using matrix metering and 3D tracking) with my two main lenses (70-200 and 200-400). I was surprised by the iso rendering coming from D3s and D4. This is really one step ahead of D3s, and I think with the D4 it wasn't the case. I process my images in Lightroom 5 and the rendering was really cool.
I've made a post on my facebook page here:https://www.facebook.com/media/set/?set=a.494153284017884.1073741832.432919643474582&type=3
