I was working softball games yesterday and heard a camera doing multiple exposures. It sounded not like Nikon or Canon. It was a D4s. I asked the guy if he thought is was "better" than D4. He had upgraded D3 to D4s, so there was no info to compare.
Also, I had to switch to 21 points of focus because I was missing my players on 9 points. I was shooting pass the subject and getting focus on fences befind them. It's just getting older and having dirty glasses.
