Nikon Japan issued a notice confirming that the Nikon D5 camera and accessories will start shipping on March 26th, 2016.
I received some information that the D5 will ship with the rumored firmware update that will allow 4k video recording for 29 minuted and 59 seconds.
Here is the full list of new products expected on March 26th:
I expect the first Nikon D5 shipment to include free Sony 32GB XQD memory card and reader.
Amazon currently lists the D5 shipping date as March 24th.
The Nikon D500 is expected to start shipping at the end of April.
