Nikon’s newest flagship professional camera, the D4, gets a premature release ahead of tomorrow’s slated official drop. Immune to the megapixels war, a 16MP sensor will allow for ISO ranges between 100 – 12,800 (expandable to 50 – 204,800). Other details including a 51 point autofocus system, 100% viewfinder coverage, 910,000 point metering system and 1080p video recording.
