As rumored before, Nikon D820 will be announced in late this month to early next month. A source told us today that D820 will have a brand new full frame sensor megapixel at 46.5MP. This is same as what rumored before. And the official announcement date will be on July 25th, 2017. As we all know, July 25 is the date of Nikon’s 100th Anniversary, seems D820 will be announced on that day.
