Nikon's upcoming D800 has been seen in the field for the first time through a new leak Saturday night. The full-frame camera should be smaller and lighter than the D700 but, as Nikon Rumors heard earlier, will have the highest-ever resolution for a Nikon DSLR. At 36 megapixels, the 7360x4912 shots (confirmed by EXIF data) will compete with those from even modern medium format cameras for sheer image size.
