Just watched Philip's half hour review of the D800 5D III and the D4. The 5D III is too soft, the D800 isn't very good in full frame and the high megapixel means that the ISO really suffers with noise and the D4 really sucks for video... That was what I got out of it... So all three very nearly have what it takes but each one misses the mark ina  big way! I'm sure the 5D III will have a firmware update to sort out the softness soon... Until then I'll keep with my 5D III but the D800 does look a great piece of kit too... 



If you're very brave, you can fix the softness yourself.....

Not for those of a nervous disposition!!

I fixed the softness! If you process the files using lightroom at the moment they come out pretty soft. Once I'd micro adjusted my lenses and started using DPP to do the RAW conversion the softness was not an issue. There were numerous threads about this on the canon rumours site.

I'd also be interested to know if there's any significant improvements to the video capabilities?
(Not too worried about stereo, as I'd never use on board sound, other than as a guide track).

The 5DIII video is a signficant improvement over the 5D2 although some thinks after 4 years we should see more.
Canon got rid of the aliasing and moire, better compression no longer uses line skipping the 5D2 had and improved bitrate at 95mbs up from 12mbs. Jello has been reduced by half and low light improved by about 2 stops.
The video resolution is a little soft compare to the D800 because of the strong optical low pass filter though removing that brings sharpness up to D800 level and improve details on stills too. However it takes on sharpening very well in post. Unfortunately the OLP filter is part of the sensor cleaning mechanism the video resolution cannot be improved through firmware so the only option without removing it altogether are Canon change to a weaker OLP.

I think they are talking about the 5DIII video.
Regarding stills the 5DIII has no softness issue only that some RAW converters like lightroom and the earlier version of DPP that came with the camera had a bug when handling RAW. The latest version of DPP fixed that.

Yes that's right. The point that Philip Bloom made and most will agree with is that for a 3K camera it really is bad that that it can't be sharp out of the camera. It's time consuming sharpenning video afterwards.

Here is another review about video
http://www.youtube.com/watch?v=opyNMck9Jhk

I would have like to see D800 HDMI out sample processed.
Neither this or the Bloom's review mention when shooting video fullframe or FX mode the video on the D800 is actually cropped close to APS-H so this might be a deal breaker for some expecting FF coverage.

How did you find this out? That completely effects the depth of field and makes shooting with a 50mm lens a 75mm lens ? Or am i missing something? That doesnt seem right??? The canon still comes up trumps but the nikons full hdmi out could be very useful... If it worked! It didnt on the above review!

It's not that bad. According to the DPreview article, the video is cropped to 91% of the usual horizontal frame (so your 50mm becomes 55mm).

Probably done to make the numbers of lines an even multiple of 1080, and facilitate line-skipping.

D800 FX video mode is 91% crop (think of it as a 1.1 crop, APS-H is 1.254 rounded up to 1.3 crop in most publications). Might be their way of handling down sampling.
HDMI out Prores 422 affects colour space but not sure who well it handle post with higher bitrate, ie sharpening, etc, during grading but it does not appear it can do anything with aliasing. Atomos Ninja is a compatable recording device but that add another £600-800 while others are more expensive.

That all makes sense. I read it as an APS-C sensor to begin with. The reality is I guess that both cameras are very capable of doing the job but it's easy to lose sight that these cameras are primarily photo cameras, the video camera comes in to play afterwards. The D800 is Nikons first real attempt at competing with Canon for video and they haven't done a bad job. For me to consider swapping back to Nikon though, they will have to overtake Canon which I don't think they have done yet.

I just wish they would sort the HDMI lead issue out on the cameras, make it a full HDMI lead and find a way of keeping it in their as that's a feature that in the field sucks.
