Just few days ago Nikon Australia published the news, Nikon D4 and D800 DSLR cameras have become the first DSLRs to pass the BBC Test OR known as the European Broadcast Union test,. Later on Petapixel also published the victory news but the thephoblographer move towards further investigation and they have published the article on October 5, “Did the Nikon D800 Really Pass the BBC Video Test?”
But take a look at the results very carefully….The end of the D800′s PDF clearly states, “This camera cannot be recommended for serious programme-making.” …see the full article (here),
After reading it Andy Quested (Head of Technology BBC HD & 3D) replied
Dear all. The cameras did not “pass” and the BBC is not and will not be using them for HD programmes.
Here are the sections from the test report
Nikon D4
10 Conclusion
The camera has very limited controls when in video mode, but has reasonable connectivity, allowing full resolution external monitoring and recording. Sound facilities are sparse, the internal microphone is adequate for note-taking or guide sound, and the microphone connector is a 3.5mm jack offering only un-balanced input.
The test procedures were as described and recommended by the EBU, in Tech 3335 (http://tech.ebu.ch/docs/tech/t…. Video performance is quite good at 1080p, much less so at 720p.
However, even though the sensor has 16.8 million photo-sites, it achieves only about 1,355×764, only a little better than 1,280×720.
Noise levels are very low, and the camera could be acceptable with ISO settings up to 6,400. Coloured spatial aliasing is present, and is clearly visible even on the camera’s LCD display (921k pixels, about 1,176×784). In theory, meticulous control of the shooting style can minimise this, by using only motivated
pans together with fairly short depth of field, such that detail out of the focused plane is always soft and therefore can never provoke aliasing. Exposure range is, potentially, as high as 13 stops, although this will be limited by the acceptability of the noise levels near black.
Nikon 800
The test procedures were as described and recommended by the EBU, in Tech 3335 (http://tech.ebu.ch/docs/tech/t…. Video performance is not really acceptable at 1080p, much less so at 720p. Even though the sensor has 36.8 million photo-sites, it achieves only about 1,355×764, little
better than 1,280×720.
The first High ISO test was done by Xerodigital and Now its time for (non-english website) focus-numerique, during the test 1DX performance was better than the D4, Canon images are usable up to IS 12800, Nikon D4 is limited to ISO 6400. The scene is illuminated at 200 lux, the Canon EOS-1D was at 1/4 s, f / 5.6 & ISO 100.

You can also compare images from the Canon 1D X with those of the Nikon D4 16 MP. So who is the winner of this clash of the titans? Overall, the Canon to the housing pro Nikon with better grain content (it is almost invisible at ISO 6400). D4 is already showing its limits to ISO 6400, sensitive to the 1D X which seems to be very comfortable. In 12800, the red mark still dominates its rival will not return the head to ISO 25600.
Take a look at quick comparison review between Sony A99 and Nikon D600.
Image sensor: both camera uses Same Full-frame sensor with same resolution.
ISO: The Standard ISO range of Sony A99 is 100-6400 expandable up to 25600, Nikon D600 have bit better, lower ISO range can be pushed to ISO 50.
AF Type: Both camera uses advance AF system but Nikon have more AF point.
Nikon D600 Hybrid AF system: Nikon D600 uses both phase and contrast detection method, for phase detection it uses Nikon Multi-CAM 4800 auto-focus sensor module with TTL phase detection, fine-tuning, 39 focus points (including 9 cross-type sensors).
Sony A99 Hybrid AF system, it uses Two phase contrast sensors, a 19-point sensor above the translucent mirror and a 102-point focal plane phase detection sensor, work together to deliver greatly improved subject tracking performance and increased precision. phase-detect focus is also available in video mode.
AF Working Range: Sony A99 have better AF working range with EV -2 sensitivity for improved performance and focus in low light.
In Camera IS: Sony A99 features Sony’s SteadyShot technology for image stabilization within the camera.
Top Continuous Shooting Speed: Sony A99 @ 6fps, Sony A99 is more fast compared to Nikon D600.
Video mode: Sony A99 is clear winner, you get Full HD @ 60fps and (Hybrid) Phase detect AF system for Continuous AF during Video mode.
Display:Sony A99 have fully Fully articulated 3″ TFT LCD with 1,229,000 Screen dots and Nikon D600 have Fixed LCD 3.2″ TFT liquid-crystal color LCD with 920,000 Screen dots.
Viewfinder: Nikon D600 features optical viewfinder.
Other features:
GPS: Sony A99 features in camera GPS, Optional in Nikon.
WiFi – Optional for Nikon, Sony Missing it.
HDR etc., Both camera offers in camera High Dynamic Range (HDR) capture. Sony Also features Multi Frame NR, Hand-Held Twilight and clear zoom technology.
Price Factor: Sony A99 is will cost you approx $800 more than Nikon D600
Conclusion: Nikon D600 is affordable and recommended for Still Photographers, but if you shoot Video + Still buy Sony A99.
