Canon UK Response to MkIII

Here is the response I received from Canon UK having questioned the LCD display and the focus issues.........

"Dear Customer,

Thank you for your recent enquiry regarding your Canon product.

Thank you for your enquiry on and about the 1d mark 3. There has been much talk about the camera in the AI servo mode and the camera locking on to its subject and getting right frame after frame.

From the responses given by Canon professionals using the camera and our own idea about how the camera works we would like to suggest the following things you might like to try to improve you’re the focus shot rate you are receiving.

Please note these are suggestions to improve your camera setting to possibly achieve better focus results.

Much of the way a photographer uses the camera and what they are used to doing is instinctive and this Canon can’ t change as this is user operation of the camera, however we have provided tools for your customer to enhances the way they can take pictures with the camera and set up the camera you your saved preferences under a user defined.

When the camera is set to AI Servo, we can suggest that you might want to change the following setting. Please try the following suggestions to see if the results you are seeking do improve.


Please press menu> Under the camera tools section move the top dial to the 8th icon.

Here you will need to go down to C.FN III : Focus drive. Press "Set" here you are able to change the focus drive of the camera to speed up or slow down. On our camera here we have set this to "Fast"

Please press the picture styles button on the back of the camera next to the

"Func." Button. Here you are presented with the many picture styles to use with the camera.

Scroll down to User defined 1, press INFO we have found that should you turn up the "Sharpness" of the camera and the "Contrast" there seems to be improvement of the cameras accuracy to lock on to the subject.


Please move to Custom function III: Auto Focus/Drive adjustment - AF Micro Adjustment. Here you will be bale to push or pull you final focus adjustment, should you find that the your camera or lenses are either from or rear focusing then you will be able to pull this focusing to achieve the best focusing results.

Another thing we have noticed her eon the canon UK help desk in our own tests here with this camera system is that the when a single focus point is selected if the focus point is not on a solid colour or tone then the focus will flicker between two different focus points.

If you are using the Ai focus, you could possibly have situations were the focus will not be confirmed, this is effect that is not different to any other of our camera systems you can could possibly see that when using high speed shooing may flag up these results more. In the advice 2. above suggests above where selecting sharpens and contrast should help to determine the edge of the subject and either drop the subject in focus or out or focus.

Much of the advice given above is subject the Canon UK Technical Help Desk tests and are recommendations to try but not fool proof answers to your problems.

However should you find that you are having issues with the camera and the way it is working then we can only suggest that you my want to get the unit serviced at the Canon UK service centre.

Should you want to talk this though with the Help Desk team then please call the Canon UK help desk on 08705143723 and ask for your call to be escalated to the Canon UK helpdesk team Please also provide the reference number 3866765.

This information is not Canons own suggestions and we are not responsible for the results what are stated. this is not Canon information but mealy their own advise and what they are finding with the 1d mark III.

With regards to the LCD sharpness once the user has zoomed in to its fullest zoom there are two things are being looked at here.

The first being the sharpness of the LCD you are viewing the second the amount of zoom that is you are looking at on the LCD monitor compared to the actual file resolution.

After making some tests if you fully zoom in to the centre of the picture we feel that you are looking further then 1.1 and indeed are looking at a very close view of the image and perhaps this means that you are looking at the out side of the pixels on the file, which is further than the normally suggested, to clarify focus.

Much in the same way you view images on a monitor with Photoshop we can consider that Photoshop it is very good to view a final image at 100% as anything else is an interpretation of the final file data.

At this kind of zoomed view the very edges of the pixels will look blurred when in combination with an LCD. It is possible that this could be the problem that you are seeing.

Canon can only suggest that we have made great improvements in this area in the last few years and are strived to improved this all the time however the issues faced are LCD resolution, and the interoperated resolution of the shot file.

We can only suggest the viewed image is an interpolation of the original file, and is used as a guide for exposure and focus checking however, to truly make sure of the exact focus we can only recommend that you view the images on your own system computer system and if need in a printed form.

Should you believe there is an issue with the cameras LCD or the Cameras processing then we advise that you send the camera in to the Canon Service centre for a complete check up.

Yours sincerely,

Canon Support Centre"
