The specs of Nikon D4s have been announced

http://www.nikon.com/news/2014/0225_dslr_01.htm


"The D4S offers selection from three image area* options that respond to imaging intent—FX-based movie format, DX-based movie format, and 1920 x 1080 crop. With recording at a setting of 1920 x 1080 crop, 1920 x 1080p full-HD movies are generated without resizing for stunningly sharp movies rich in detail."

Very curious to see the hdmi out recorded to an external device.
 
They remark quite strongly that the sensor is faster, so the softness+aliasing+moire of the D4 should be gone... or maybe it's just marketing speak, we'll see. Looking at the specs, HDMI out seems to be... on par with the D5300 (man, I'd be so glad if I could put a speedbooster in front of that one).

Hi Samuel, what do you think about HD movies not being resized but a crop of the sensor? Doesn't that mean there will be no binning nor line skipping?

Obviously I'm not Samuel, but the 2,7 x crop of the old D4 was never criticized for softness.


Found this in Voldemort's castle: "... but as I'm sitting here at the press conference, there are a few interesting tidbits, like ProRes support, 42MBps at 50/60 FPS... "

it may use different sensor readout modes for each crop --> we need to see actual footage

in principle, 2.7x should be completely clean (1:1 crop), the others depend on the implementation
 
Nikon is getting alot better with video with every new body they release, so this should be very good for a 1080p compressed codec. Thus it will probably be the first really good full frame offering from Nikon, and I can only dream about the ISO performance this camera will have.

My guess: In a year we will have Nikon full frame 4K.
 
that and a log mode preserving all the DR from the sensor, and it's as good as RAW --> works for me too
just dreaming, I'm afraid...

I don't think they did the numbers right

their facts are:
* colorcheckr white spot is clipped at f/2.8 but not clipped at f/4
* colorcheckr black spot has some detail at f/22 if you push the image in post by two stops
* the difference between white and black spots in the colorcheckr is around 5 stops

to me, that means 11 stops of DR (6+5), but they add the two stops that they pushed the image in post and get a result of 13

they even talk about using "multiple exposures", which may mean stills, not video (they are very similar on Canon DSLRs, but very different in the shadows in Nikon DSLRs; I made this mistake the first time I used a Nikon DSLR for video)


edit: the good part is that they explain their methodology in detail, and they have tested other cameras too: here
 
From Nikon website
[h=2]Professional-worthy 1080/60p Full HD video with comprehensive operability, rich, noise-free color from ISO 200 to 25600, and an incredibly sharp 1920 x 1080 crop format[/h]Sounds like the best format is super 16 frame size
 
LOL from Nikon, so you get the best format of a full frame camera at 16mm, it is a bit stupid. In the end I don't care too much because I prefer the apsc format for video and the D5300 hopefully D7100 is much more affordable range. But it would have been nice for the Nikon personal image to see something a bit better.
 
Yep, D4s is as bad as D4. Damn it. Our hopes are gone now...

On the artistic side, however, that video is really really good.
