I am working on a couple of articles related to the new Nikon Df camera (see the announcement / overview and pre-order options) and I decided to post a size comparison between Nikon’s most current line of full-frame DSLR cameras. Starting from the left, we have the flagship Nikon D4, then the Nikon D800, followed by the Nikon D610 and finally, the new Nikon Df (click on the image for a much larger version):
As you can see, the Nikon Df has a similar size as the Nikon D600 / D610 in terms of height. When looked at the top, it is thinner due to a smaller grip and less protruding pentaprism / flash area. Weight-wise, it is about 50 grams lighter.
