I have an update to the previously reported Nikon D600 specifications (new/updated specs are on top, marked in bold).

I also have two corrections to make - the D600 will have a built-in AF motor and it will not have built-in GPS.

There are also rumors that Nikon has invited some European resellers for a meeting in Casablanca on 28 May, 2012. I am not sure if this is related to the D600.

New/updated Nikon D600 specifications:

24.7MP full frame sensor

Weight: 760g (850g with battery and memory cards), the D800 weights 900g

3.2" LCD with 921K dot with ambient sensor control

HDMI output

Video compression: H264/MPEG-4

Full HD with 30p, 25p, 24p, HD with 60p, 50p, 30p, 25p

Viewfinder coverage: 100% for FX , 97% for Dx

The Nikon D600 will have built-in AF motor

The body most probably will be weather sealed

The D600 may not have built-in GPS as initially reported

ISO range: 100-6400 (with Lo-1 ISO 50 and Hi-2 ISO 25,600)

39 AF points (with an option of 11 AF points), 9 cross-type AF points

AF face detection

Exposure compensation: ±5 EV (same as the D800)

The D600 will probably use the EN-EL15 rechargeable Li-ion battery
