Medium format vs. full frame sensor,cameralabs tested both the camera, the winner is Phase One IQ160 but the result of Nikon D800 look very impressive, the Nikon D800 look just one step behind the Phase One IQ160 Monster Camera.
Camera / shot settings
Phase One with a Schneider LS 80mm f2.8 lens and Nikon D800 with a Nikkor 24-70mm f2.8, set to 70mm. Both bodies were then set to their base sensitivities of 50 ISO for the IQ160 and 100 ISO for the D800, and both lenses set to f8.
Nikon issued a firmware update for locking-up issue and other minor problems, see our previous post – Nikon D800 and D4 problems
D800 Firmware Update – version 1.01(Modifications enabled in this version)
When a still image was captured while viewing existing images in playback mode, the monitor turned off, the memory card access lamp glowed steadily, and, in some rare cases, the camera ceased to respond to operations. This issue has been resolved.
When the Wireless Transmitter WT-4 was used with certain settings applied, RAW images were also transferred when Wireless transmitter>Transfer settings>Send file as was set to JPEG only. This issue has been resolved.
A dark shadow sometimes appeared at the bottom edge of images captured with Active D-Lighting set to any option other than Off with Image area set to 5:4 (30×24). This issue has been resolved.
D4 Firmware Update – version 1.01(Modifications enabled in this version)
When a still image was captured while viewing existing images in playback mode, the monitor turned off, the memory card access lamp glowed steadily, and, in some rare cases, the camera ceased to respond to operations. This issue has been resolved.
When network functions were used with certain settings applied, RAW images were also transferred when Network>Send file as was set to JPEG only. This issue has been resolved.
When an option that utilized the main command dial was selected for Custom Setting f15: Playback zoom, and an image was zoomed in or out with playback with certain settings applied, shooting shutter speed, aperture, and exposure compensation settings were sometimes changed. This issue has been resolved.
Now after 5D mark III light leak problem its time for Nikon D800 & D4, Nikon identified a small unit of Nikon D800 and D4 can lock up and become unresponsive, you can prevent this if you disable the highlight and RGB histogram displays of the camera.
In a statement to PDN Online, Nikon Said
Nikon has received reports of a small number of D4/D800 users who are experiencing ‘locking up’ issues, where the camera becomes unresponsive until the battery is removed and reinserted,
Nikon’s statement reads. “Nikon is investigating a permanent solution to this issue and will update users accordingly. To immediately resolve this issue, users can turn off both the ‘Highlights’ and ‘RGB Histogram’ display options in the ‘Playback Display Options’ sub-menu found in the ‘Playback’ menu.
Nikon also verified a small “run” of Nikon D800 is suffering from a viewfinder problem,
the viewfinder show out of focus problem identified by fstoppers , the camera did focus properly the scene still looked a bit out of focus through the viewfinder, In a reply to this problem Nikon said “a run” of D800s have an issue with viewfinder alignment.
DxOMark published the result of Canon 5D Mark III sensor, the overall score of 5D mark III sensor is 81, before jumping to any decision please remember that the test score of DxOMark is based on Sensor RAW output, the low-light score of Canon 5D Mark III is 2293 ISO, Canon EOS 5D Mark III nearly ½ Stop better in low light conditions compared to Canon 5D Mark II (1,815 ISO).
The dynamic range score is almost same as 5D Mark II, the 5D mark III shows its improved performance behavior at high ISO test only.
Canon 5D Mark III vs Nikon D800
On sensor war Nikon D800 is a clear winner, the overall score, dynamic range, portrait color depth and low-light score is better than the Canon 5D Mark III.
A video Test done by Joe Marine, Nikon D800 sensor captures more light compared to 5D Mark II and 5D Mark III under low or High ISO settings, but both 5D Mark II and 5D Mark III have less noise at high ISO with bit flat details due to in-camera noise reduction filters.
Nikon D800 performance is excellent up to ISO 1600 the sensor captures more details compared to its competitors
At High ISO Both 5D mark III and II have less noise,
Personally I will prefer 5D mark III or II for video, Which camera do you prefer? – Nikon OR Canon – Share your thoughts with us

This is a shootout of the new Nikon D800 and Canon 5D mkIII DSLRs, with a focus on the video quality in particular. More more detailed info, you can read my write-up of the tests at www.crisislab.com.
More and more news is coming about Nikon D800, We are Starting from Image comparison to Video,
Image Test
dslrmagazine Done a 30MP+ test with Leica S2, the Hasselblad H4D-40 and the Sigma SD1 Merrill, Only Hasselblad H4D-40 giving out similar image quality to D800 at base ISO, in overall image comparison test Nikon D800 performance was outstanding
Nikon D800 video have more details compared to Nikon D4
Latest artcile published at EOSHD suprised us, “$3000 Nikon D800 thrashes flagship $6000 Nikon D4 for video” and yes its true,
The 35mm full frame sensor of the Nikon D4 is unbelievably soft at video, Nikon paid no serious attention at the sensor architecture design stage to video. Nikon D800 has a Sony CMOS Full frame sensor which has double the resolution for half the money than the D4.
Latest test at DxOMark shows us Nikon D800 overall score is the best sensor score ever measured at DxOMark Lab and Nikon D3s is still the undisputed king of low light photography.
the Nikon D4 gives perfect 1080p in crop mode but the full sensor image is soundly beaten by the consumer level Nikon D800.
