When canon announced 1D X many wildlife photographer get disappointed, since AF was unavailable on the EOS-1D X when lenses with a maximum aperture of f/8 are used.
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.
Now with the recent Firmware update you can use lenses with F8 aperture, see more details below.
Pres Release
LAKE SUCCESS, N.Y., October 17, 2012 – Canon U.S.A., Inc., a leader in digital imaging solutions, today announced a new firmware update in response to user requests which further enhances the capabilities of Canon’s flagship EOS-1D X Digital SLR camera. The EOS-1D X will now be capable of AF point illumination during AI Servo AF and cross-type AF for maximum apertures as small as f/8. The new firmware update is available now at no charge from the Canon U.S.A. website and can be downloaded by end users or through Canon Factory Service Centers.
AF Point Illumination During AI Servo AF
To support the needs of wedding, portrait, sports, wildlife, and theatrical performance photographers working in low light, the new firmware allows AF points in the EOS-1D X’s viewfinder to be illuminated in red when the shutter button is pressed halfway during AI Servo AF, for easy viewing of the selected point. This valuable feature will enhance the photographers’ ability to aim the camera accurately in low-light conditions, and when photographing dark subjects. To preserve exposure-metering accuracy, illumination is intermittent, not continuous. Three choices will be selectable from the menu system – Non-illuminated, Illuminated (Normal) and Illuminated (Brighter).
Cross-Type AF Support at f/8
The EOS-1D X is equipped with an innovative 61-point High Density Reticular AF System featuring up to 41 cross-type AF points, depending on the lens in use. The cross-type AF points recognize a wide variety of subject matter, making them highly desirable for maximum autofocus performance. Until now, cross-type AF on the EOS-1D X has been limited to EF lenses and lens/extender combinations with a maximum aperture of f/5.6 or larger. The new firmware allows cross-type autofocusing with the center AF point even when the maximum aperture of a Canon EF lens/extender combination becomes as small as f/8. Ideal for wildlife photographers and others who often use EF super-telephoto lenses with extenders, this new feature greatly expands the range of EF lens/extender combinations that support autofocus when used with the EOS-1D X.
If AF point expansion is selected with an f/8 maximum aperture lens/extender combination, the four AF points surrounding the center point will act as AF Assist points. This option effectively expands the size of the AF detection area to enhance autofocus performance with subjects that are small in the frame and difficult to track, such as small animals and birds in flight. AF points above and below the center will be sensitive to vertical contrast, while points to the left and right will be sensitive to horizontal contrast.
The DxO Mark Score of Canon 1DX is not confirmed yet but take a look at Canon 1Dx vs 5D Mark III High ISO images comparison, the Canon 1Dx images showing better color and more details at High ISO compared to 5D Mark III.
If the lighting conditions you’re shooting in doesn’t require an ISO over 3200, both cameras will deliver almost identical quality images. However, if you need to shoot with an ISO 6400 and above (especially at 12,800 and above), the Canon EOS-1D X will deliver a superior, cleaner image. This does not mean the Canon EOS 5D Mark III cannot render deliverable images at ISO 12,800, it just means that the Canon EOS-1D X controls the noise in the shadow area much better in a high ISO. See it for yourself in the images below.
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.

Finally first comparison between the Nikon D4 and the Canon EOS 1D X is now available, Matt head of xerodigital tested both Canon 1D X and Nikon D4 side by side, based on test result the overall performance of 1D X is really impressive.
Camera / shot setting: Images captured at RAW mode, processed in Lightroom 4, sharpening and noise reduction set to zero.
Main points of the review
ISO performance: Nikon D4 seemed to have cleaner highlights, while the Canon 1Dx appeared to have better contrast and possibly cleaner shadows. In the end, if we have to award a point here and pick a winner, it’s the Nikon D4 – by a hair
AF in Low-light: During the low-light Test condition Nikon D4 performed better, focuses bit quickly than Nikon D4.
AF Speed: The Canon 1Dx ABSOLUTELY DESTROYED the Nikon D4 in the AF speed test. Canon 1D X is three times faster than the Nikon D4.
Autofocus Consistency: Winner Canon 1D X
Shadow recovery: Winner Nikon D4
AFTER A DECADE OF SHOOTING PROFESSIONALLY WITH NIKON CAMERAS, MATT IS THINKING OF SWITCHING TO CANON…
A head to head comparison between the two flagship cameras. In the end, a decision is made!
Canon Officially Confirmed that Canon 1DX and 24-70mm F2.8L II USM lens is delayed,
