Bryan Peterson posted this on his Facebook page, claiming to be from a reliable French “inside” friend:
“Two new Nikon’s-The D800, at 20MP, full frame, retail price of $2495.00 and Nikon DX-4, full frame at 19-20MP with a retail price of $5,000.00 and both will be announced by late September 2011!”
I am not sure what to think about this rumors – 19-20MP is a rather unusual size for a full frame sensor and the $5000 price tag of the D4 (I assume the DX-4 was a typo) means that it will be cheaper than the D3s (currently priced at $5200). I expect the new full frame DSLRs from Nikon to have a higher price tag than their predecessors.
Bryan Peterson has several published photography books.
