This has been a total joy to own. Its simply the very best you can buy. Detractors are usually people who cant afford it or sour faced Canon owners who have second best. You DO need 36mp, what depressed me about the D200 is taking a full length portait and zooming in on the head afterwards to find lack of detail in areas, now I know every eyelash is there crisp and well defined. Also you can print from part of the picture and know you have enough pixels. I dont know why you would buy a D600, the price difference is not that great now and google D600 dust issues there have been problems Nikon hasnt come clean over, no such problems with the D800. Only wish I'd ignored the reviews and gone for the D800E, theres always that thought that it would be even better. The only minus about this camera is it could feel better in the hand, the grip is too 'boney' my D200 actually feels nicer to hold. Go and get one if you can you will have the best. ONE WARNING this camera requires top technique to get the results, that means tripod where possible, higher shutter speeds than you usually would, the best lenses, understanding depth of field. If youre just going to wave it around like a compact you wont get the very best results the 36mp show up the slightest fault in your technique. Nikon even released a booklet in the US about strict technique with the D800 to prevent owners returning them for less than perfect images due to user failings.
