I just fell into a D4 deal and am trying out the camera. I've been through the settings to match it up to my D810 and D3s backup. The SOOC JPGs look sharper, contrastier, more vibrant than what I am used to seeing, maybe a little too much so. I'm planning to calm it down a little. Also, the ISO seems to run around a 1/2 stop lower to get the same histogram. Color rendition seems more like the D3s, the D810 looks a little yellow by comparison when the cameras are set the same.. Other than the joy(?)pads and size/weight, there is a lot to like with the D4. Results so far are the most different looking Nikon JPGs that I have seen in a while, just wondering if this is unusual or common. Any setup tweaks that really work for those of you familiar with the D4 would be appreciated. Going to look at the NEF's now.
