EOS-1D Mark II - AF recall preparation

1DMkIIIBack at the beginning of March we wrote about Canon's latest plan for further improving the AF performance of it's EOS-1D and EOS-1Ds Mark III cameras. Now and for the second time the blabpictures EOS-1D Mark III is going back for rework on it's AF. Previously it's had the mirror box fix, though not that it seems to have needed the work, it's always been able to nail focus on the subjects it's been given. There has been some feedback on dpreview, fredmiranda and many other forums that this latest AF fix makes the camera pretty much what most users expected from the start. As the camera we have is one of those from the first few months of production it's wise to send it in and see if they can make it even better for free. Would be important to have proof of the fix if you were ever to sell it.

After reading a few other forum posts on the topics we created a short checklist of things to do before sending a camera in for rework, though it's also a good idea to do this before any service.
  • Write down your camera body serial number - make sure you get your camera back
  • Back-up the camera to a memory card
  • Remove all the other accessories the service team don't need and can lose; strap, eyecup, battery etc.
  • Make sure the body cap is securely fitting to prevent the ingress of dust and stuff in the shipping process
These items may seem like sense, but how do you backup the camera? Canon EOS-1D Mark III models have function to store a snapshot of your camera configuration on a memory card. You can put up to 10 different named files on a card, and the snapshots take up very little space. With this backup of the camera if service need to fully reset your camera then when it comes back you simply load in the backup and your camera is set-up just as it was when you entrusted it to service. Most people think this only backs up the custom functions, but in fact just about everything is saved, the power off time, the owners name, the display preferences pretty much everything except the time and date! 

Backup EOS-1D Mark III / EOS-1Ds Mark III
Hit menu and move the to the third yellow tools menu and the first item is Save/load settings on media. Press the SET button and then Save and Load are displayed, hit SET again with Save selected.  You are prompted for a filename or can choose the cameras own choice "CAMSET01.CSD". I select my own filenames, but they must have eight characters. I chose "BLAB_1D3.CSD" and then saved the file. Now don't format the card while the camera is away and when it comes back go through the process and Load the settings back in to the camera.

One tip here is to use a small old SD card for saving your camera configuration on. Then copy the card to your computer, maybe upload your settings to somewhere online, and put the little memory card in your camera bag. Now if you have the misfortune to get a breakdown any loan camera you pick up can be set-up just how you like it in a matter of seconds and you won't need an instruction manual to do it!

AF Microadjustment C.Fn III-7
One thing that many people are reporting is that their AF micro adjustments t are reset to zero as part of the service work. Your back up will keep your old settings. Many people are now saying the AF micro adjustment of their camera is zero for all their lenses so you might need to reset these to zero after loading your back up; just set C.Fn III-7 to 0:Disable.

Any readers with experience of the recall and some comments about their camera performance post recall please post in the comments.

Breaking news.... EOS-1D/Ds Mark III AF updates

It's been rumbling along for a while, but as if to prove that Canon will continue developing products in response to user feedback, they have today quietly announced some updates to the EOS-1D and EOS-1Ds Mark III models. You'd expect that two years down the line a company would stop developing and just get on with whatever they're doing next, but Canon do seemingly feel the pain of their photographers, some of whom have been having issues with the cameras. 

I say they've announced them quietly, because they haven't seemingly told anyone about it yet. We just picked it up by chance looking through the support pages of the Canon UK website.

So, if you have an EOS-1D Mark III or EOS-1Ds Mark III, you want to read this.
There are two parts to it and you should read both as they will be of interest. 
First up is a heading entitled "Announcement regarding AF accuracy in EOS-1D Mark III and EOS-1Ds Mark III cameras". This talks about AF accuracy when any AF point other than the central point is used. Canon are offering free AF accuracy checks and alignment for affected products. To help further they have also produced a web page with some extra information on getting the very best out of the AF systems in the EOS-1D Mark III when shooting in AI Servo focus mode. This gives tips on setting the camera for different situations to ensure you get the very best performance possible. It also includes a section on Canon's AF performance philosophy so you can understand what they are aiming for. 

The second part is about abnormal mirror operation and Err99 on the EOS-1D Mark III and EOS-1Ds Mark III. Canon are offering free repair to any affected products and have also produced an updated firmware (1.2.5 for EOS-1D Mark III and 1.1.4 for EOS-1Ds Mark III) that gives more information when error codes appear so that better support can be given. 

More info on the firmware updates (applies to both models):

The following improvements have been incorporated.

1. Corrects a phenomenon associated with image display during Live View shooting. Corrects a phenomenon in which a displayed image becomes pitch-black if it is zoomed in during Live View shooting.
2. Improves reliability of USB communication. Corrects a phenomenon in which "busy" may continue to appear on the camera, if the USB cable is disconnected during USB communication.
3. Changes the error indications that are displayed on the camera. In previous firmware, if an error is detected "Err 99" is displayed on the camera in most cases.
Firmware Update Version 1.1.4/1.2.5 further specify the error indications as follows:

10 Malfunctions related to files have been detected.(*1)
20 Malfunctions related to the mechanical have been detected.
30 Malfunctions related to the shutter have been detected.
40 Malfunctions related to the power source have been detected.
50 Malfunctions related to the electric control have been detected.
70 Malfunctions related to images have been detected.
80 Malfunctions related to the electric control or images have been detected.
99 Malfunctions related to the mechanical charge mechanism have been detected.
*1: Err 10 is only displayed on the EOS-1Ds Mark III and other error numbers are shared.

If malfunctions in the camera are detected, "Err XX" will be displayed. A two-digit number that corresponds to the malfunctions detected by the camera will be displayed in the "XX" section of the error number. Other than the error numbers listed above, there are other numbers such as "01". In that case, provide appropriate handling and servicing by following the details displayed on the LCD monitor of the camera.
If an error code appears frequently, the camera is malfunctioning; therefore, note down the error number and contact our service center.
The changes in the display of error indications only apply to the EOS-1D Mark III and EOS-1Ds Mark III. The above error numbers and details do not apply to models other than the specified models.

Have you got one of these cameras? If so, let us know how it goes and what you think of the new information.
