OT: NIKON enters the video battle field.

Arrr, I see Craig, makes sense – thanks for the anwser. I guerss that’s what the spec means when it talks about ‘crop mode’ for video. In this mode I guess it’s only using the central 1920×1080 of it’s sensor.

The problem is that you need more than 1920×1080 pixels to pull a decent picture from just one sensor (the SONY EX has 3 x 1980/1080 CMOS).
The more you crop, the less you lose the advantages of a big sensor. A certain cropping would help, but in the end all is about processing power and good algorithms for quality real time downscaling.

I think you’re the biggest thing about the D4 is the clean uncompressed HDMI (10bit as well?) as there is nothing else save anyone using Nikon glass that’s revolutionary about the specs. I imagine at somewhere like Atomos there’s a huge sigh of relief, as nikon has broken the unwritten cartel to deliberate cripple of the hdmi by the camera manufacturers (as they are camcorder manufacturers), I think this makes it a lot more difficult for canon (on 5dmk3) not to have a clean hdmi out, likewise the GH3 (although fair play for at least allowing the hacking to go unhindered), and Sony as well. I’d expect clean hdmi to be the norm within 18mths, and further convergence and hybridisation of DSLR & camcorders.
Now I only need prices to come down on SSDs! For 6 ninjas.

Lets see what happens.
The four companies are japanese, so nobody know how things may und up.

The ugly
The downsampling of the sensor is similar to the Nikon J1, a $499 mirrorless camera. According to Nikon, “subsampling is only along each horizontal video line; there’s no sub-sampling between video lines. ” Frankly this is bloody ridiculous. I’ve seen the results of this on the J1 and it isn’t pretty – sheering on fine diagonal patterns and very soft detail. I expect better from a pro DSLR. With that in mind don’t expect resolution on the D4 to beat the GH2 or Canon 1DX with DIGIC 5.
