I preview the Nikon D850. The D850 is supposed to be fully announced on August 15th or 16th but we never everything about it besides the price. The D850 packs the D5 processor, 46 megapixels with full 4K video. 153 af points, built in focus stacking for macro photography, dual memory card slots and much more. It also does 8K timelapse but is that just a gimmick? Is the Nikon D850 exciting or just a waste for Nikon's 100th anniversary? Does it seem like it beats the Canon 5D Mark IV or the Sony A7R II, A99 II?
