4. Nikon D400
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.
Nikon D800 is coming with and without low-pass filter according to Digicam.info, Both the model will have same core specification, the model with low-pass filter name is Nikon D800 and model without low-pass filter name is Nikon D800E.
Translated from google
Readers, courtesy of information on the Nikon D800.
Nikon’s new digital SLR model with a low-pass filter is a D800, which called for models with non-D800E.
D800 and D800E are different and only the presence of low-pass filter, and other specifications are exactly the same.
Canon 1D X vs Nikon D4 Specification comparison review, read more details below Buy Nikon D4 from Amazon Buy Canon 1D X from Amazon Nikon D4 with More shooting modes: With Canon 1D X you can use Canon EF lenses only, but with Nikon D4 you can use DX and FX lenses, Nikon D4 offers four image area options: FX format (36.0 x 23.9 mm), 5:4 crop (29.9 x 23.9 mm), 1.2x crop (29.9 x 19.9 mm) and DX format (23.4 x 15.5 mm). The camera also offers three image area options for Full HD video thereby tripling its potential for moviemaking.
About the Sensor: Nikon D4 features 16.2 megapixels Full frame (36 x 23.9 mm) CMOS Sensor and Canon 1D X 18.1 megapixels Full frame (36 x 24 mm) CMOS Sensor , the EOS-1DX’s photodiodes are 21% larger than those in the 1Ds Mark III.

AF Points compatible with Apertures
Canon 1D X is disappointing to many extender users.AF is unavailable on the EOS-1D X when lenses with a maximum aperture of f/8 are used.
In Nikon D4 11 focus points are fully functional when lenses with a maximum aperture of f/8 are used. Five central focus points and three points to the left and right of them in the middle line are compatible with f/8. This enables very precise focus acquisition with sports photography and the like when super-telephoto NIKKOR lenses are used with a teleconverter (2.0x) at a combined aperture value of f/8.
F8 Lens: adding a 1.4x extender to an f/5.6 max aperture lens results in an f/8 max aperture lens or adding a 2x extender to an f/4 max aperture lens results in an f/8 max aperture lens.
AF Engine: Canon 1D X AF system uses dedicated Digic 4 processor , EOS-1D X’s comes with 61-point Area AF system that includes 41 cross-type sensors and 5 dual-cross type AF points for extra precision.
Nikon D4 features same (old) AF engine used in D3 DSLR – Multi-CAM 3500FX autofocus sensor handles 51 AF points, aligns its 15 cross-type sensors in the central viewfinder area to detect contrast in both vertical and horizontal lines for better AF performance.
Predictive tracking: Both features Predictive tracking Canon 1D X Predictive tracking is better, read the details below
Nikon D3 / D4 AF Engine Multi-CAM 3500FX capable of maintaining accurate focus even on a high-speed subject such as an F1 racing car traveling in excess of 300km/h.
However, simple predictive tracking AF does not provide maximum focusing performance for a subject that abruptly changes direction moving at high speed or a subject with low contrast moving randomly. To focus accurately on such a subject, the AF system must accumulate data of the locus of the subject’s movement using multiple focus areas so that appropriate judgment can be made.
Canon 1D X offers six presets for different shooting situations, Each of these presets can be adjusted for ‘Tracking sensitivity’
For faster predictive focus measurements so that the EOS-1D X can begin predictive tracking as soon as a subject begins to move.
Canon EOS-1D X AF mode presets, defined by subject behavior:
1. Versatile multi purpose
4. Subjects that accelerate or decelerate quickly
2. Continue shooting, ignore obstructions
5. Erratic Subject Movement
3. Instantly refocus suddenly with obstructions
6. Subjects that change speed and move erratically
Six preset Case studies
There are six AF ‘Case studies’ preset within the EOS-1D X
Case 1 is for general purpose shooting that provides accurate and fast focus across a wide range of shooting situations.
Case 2 is designed for situations where the subject may move away from the AF point momentarily.
Case 3 allows you to instantly focus on subjects that enter the AF point area.
Case 4 is designed for subjects that change speed or direction rapidly.
Case 5 is designed for use with automatic AF point selection, Zone AF and AF Point expansion and subjects that move erratically, up and down or left and right.
Case 6 is for subjects that change speed abruptly and move erratically. Like ‘Case 5’ it is used with Automatic AF point selection, Zone AF and AF Point Expansion.

Both Canon 1DX and Nikon D4 captures Full HD movie @ 30, 25, 24 fps, but with Nikon you get more options such use of expandable ISO range in video shooting and you can record 1,920 x 1,080/30p Full HD and HD movies in three formats that are FX-, DX-based and 1,920 x 1,080 crop movie format.
Storage: 1DX coming with two slots of high-speed UDMA 7 Compact Flash cards, D4 also comes with two slots one for UDMA 7 and the other slot for the new XDC card format.
Price: Nikon D4 cost $800 less than the Canon 1D X.
Conclusion: Canon 1DX have more advance core specification than the Nikon D4, But Nikon D4 is more versatile and Canon 1D X have some limitations.
Canon 1 DX offers more advance AF system, Canon used dedicated DIGIC IV processor as AF engine and Dual DIGIC5+ image processor for image processing, you also get two extra stops of Standard ISO range.
But, AF is unavailable on the EOS-1D X when lenses with a maximum aperture of f/8 are used. (ex adding a 1.4x extender to an f/5.6 max aperture lens results in an f/8 max aperture)
Nikon D4 used same AF engine as used D3 and only single core Expeed 3 processor is used for processing images, But Nikon D4 is more versatile, It offers crop mode still and video shooting and you canon use FX and DX lenses in D4. No F8 issue, In Nikon D4 11 focus points are fully functional when lenses with a maximum aperture of f/8 are used. Nikon D4 offers iPad and iPhone wireless shooting capability, you also get a new slot for new memory card format (XQD).
