From Canon USA
It has been confirmed that auto-focusing may not function at f/8 aperture on some Canon EOS-1D X Digital SLR Cameras with firmware Ver. 1.1.1. We offer our most sincere apologies to customers using this product who have been inconvenienced by this issue. The support measures for this phenomenon are described below.
Firmware Ver. 1.1.1 enabled the center AF point to autofocus when the camera is used with lens/extender combinations whose combined maximum aperture is f/8. On some of the cameras with firmware Ver. 1.1.1, auto-focusing does not function at f/8 aperture. *This phenomenon does not occur with a camera which firmware has been updated by a user, or by Canon service center.
Canon EOS-1D X Digital SLR Cameras with the sixth digit from the left in the body number (serial number) is 4 or 5 are affected.
Example: Body No. xxxxx4xxxxxx or xxxxx5xxxxxx
*Even if the sixth digit from the left in the body number (serial number) is 4 or 5, the following cameras are not affected units.
*Look for a white dot in the battery compartment
Overwriting the firmware activates auto-focusing at f/8 aperture. To accomplish this, please download the firmware Ver. 1.1.1 available for download from Canon Web site, and overwrite the firmware of the camera.
Red AF Point Illumination…..
…. sort of.
Canon did a great thing and listened to the wishes of their customers, and spent some considerable time changing the way the AF point illumination worked on the EOS-1D X in AI Servo. Instead of a solid red illumination like the EOS-1D Mark IV, we now get a blinking AF point. Why does it blink instead of being solid? It probably has something to do with metering. While the blinking AF point is a new thing for all of us, I think we’ll get used to it in no time. I may actually take this camera over the 1D4 for lowlight shooting and birding.
My preferred new settings for the EOS-1D X
Menu > AF5 > AF Status in viewfinder > Show outside of frame
I do this because the blinking “AF” graphic in the viewfinder is quite distracting
Menu > AF5 > VF Display illumination > Enable: On > Q > Illuminated: Normal
I found the “Brighter” setting to be a bit distracting this AM while shooting some avian creatures. I will probably add this setting to “My Menu”, just in case there’s a situation where the brighter point is needed.
I haven’t had the chance to try it out yet, I have an EF 800 f/5.6L IS at home, however there are no teleconverters here. I hope to get out this evening in the yard and do some shooting with a 1.4x TC.
EF70-300 f/4-5.6L IS supported with a teleconverter?
f/8 support with the EF 70-300 f/4-5.6L IS! Yes, Canon has put this lens on the list of lenses that are supported now. As most of you know, mounting a TC to the EF 70-300 f/4-5.6L IS is mostly not possible. However, if you zoom the lens to about 250mm, the rear element retracts enough inside the lens to mount a 1.4TC. I would only recommend doing this as a last resort. If I did put a 1.4TC on the 70-300L, I would put it right to 300mm and not move it from there. I’ll give that a go tonight and see how it goes. As most of you know, I love the EF 70-300 f/4-5.6L IS.
What about my EOS 5D Mark III?
It may not be as simple as just updating the firmware in the same way. If you remember the story about getting f/8 to work on the EOS-1D X with a Kenko teleconverter, Arthur Morris was unable to make the EOS 5D Mark III do the same thing with the exact same teleconverter. The fact that Canon hasn’t updated both cameras at the same time tells me there are indeed differences in the AF systems. I am reminded only the EOS-1 line has ever had f/8 autofocus, so it may not be something that gets added to the 5D Mark III anyway.
The red AF points in AI Servo mode, I’d wager we’ll be seeing it in the EOS 5D Mark III in the near future.
EOS-1D X Firmware 1.1.1 Available for Download
To support the needs of wedding, portrait, sports, wildlife, and theatrical performance photographers working in low light, AF points in the EOS-1D X’s viewfinder can now be illuminated in red with a half-press of the shutter in AI Servo AF mode, for easy viewing of the selected point. Illumination is intermittent, not continuous, and does not interfere with metering accuracy. Two brightness levels are available for the most suitable level of illumination in dark settings and illumination is fully compatible with the range of focus points and focus zone selection options on the EOS-1D X.
For best results, the following additional menu settings are suggested when using AF Point Illumination in AI Servo AF mode with Firmware Ver. 1.1.1:
- AF Point Display During Focus should be set to the first option, Selected (constant). This setting will allow the camera to display the selected focusing point while the shutter button is pressed halfway.
- Optionally, AI Servo 1st Image Priority can be set to Focus Priority to ensure that focus is achieved before the shutter is released.
- If you wish to recompose the image after focusing in AI Servo AF, use the EOS-1D X Custom Control menu to change the setting for half-press of the shutter button from “Metering and AF Start” to “Metering Start.” This will allow you to control focusing with the AF-ON button. Once you are satisfied with the focus, lift your thumb off the AF-ON button, recompose and shoot.
Crosstype AF Available for Maximum Apertures as Small as f/8
Ideal for wildlife photographers and others who often use Canon EF super-telephoto lenses with extenders, the new firmware allows cross-type autofocusing with the center AF point when the maximum aperture becomes as small as f/8. This new feature greatly expands the range of EF lens/extender combinations that support autofocus when used with the EOS-1D X. Please refer to the list of compatible lenses below.
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 appear small in the viewfinder 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.

We knew more would come eventually, but when?
I’m told new stock should start hitting retailers sometime this month and next month, it may not be enough to clear the preorder backlog though.
