Just now i am testing the Nikon D4, i have shoot some soccer with that body and one 200-400/4 VR II lens.
Normally i am shooting in RAW only, and do all my editing in my computer.
Since i wanted to test how good Jpeg-files the D4 can produce, i shoot in RAW only.
But all the photos in this is "post has been converted in the camera.
Using only the tools to straighten and "trim" (crop) the images.
Which uses the cameras "Jpeg-motor" to create Jpeg-files.
The only post processing whatsoever, is that i resized the images with Lightroom.
