In the 5D3 in AI Servo AF mode, I would like to confirm if the AF configuration tool (tracking sensitivity, accel/decel tracking, AF point auto switching) is active in the 61-point AF area auto selection? This is not clearly stated in the manual and AF guide. Thanks in advance.

Canon has issued an advisory on the issue

To Users of the EF200mm f/2L IS USM and EF800mm f/5.6L IS USM Lenses with the Canon EOS 5D Mark III Digital SLR Camera.

Thank you for using Canon products.

We have confirmed that when the EF200mm f/2L IS USM and some units of the EF800mm f/5.6L IS USM lenses are used with the Canon EOS 5D Mark III Digital SLR Camera, the Lenses may emit an abnormal noise.

The Canon EOS 5D Mark III Digital SLR Camera does not need to be repaired as a result of this phenomenon.

The support measures for this phenomenon have been decided and they are as described below.

If either of the Lenses is attached to the camera with the Image Stabilizer switch on the Lenses set to ON, the Image Stabilizer will synchronize with the autofocusing (AF) function and an abnormal noise may occur. This abnormal noise does not affect captured images.
This phenomenon only occurs when the camera is used with either of the Lenses, and does not occur when the camera is used with other lenses.

Affected Products
EF200mm f/2L IS USM Lens
EF800mm f/5.6L IS USM Lens

*This phenomenon does not occur with cameras other than the EOS 5D Mark III.

*If the fifth and sixth digit of the six-digit alphanumeric number that is imprinted on the lens mount of the above EF lenses is of any of the following numbers, the lens is affected.

    EF200mm f/2L IS USM: If the fifth and sixth digit is 00, 01, or 02.
    EF800mm f/5.6L IS USM:If the fifth and sixth digit is 00, 01, 02, 03, 04, 05, or 06.

The Lenses affected by this phenomenon will be inspected and repaired free of charge beginning May 21, 2012.  If you own one of the affected Lenses, please contact our Customer Support Center.

This information is for residents of the United States and Puerto Rico only. If you do not reside in the USA or Puerto Rico, please contact the Canon Customer Support Center in your region.

EOS Bodies / 5D3 automatic LCD brightness working?
« on: April 11, 2012, 12:11:18 PM »
It seems that when the light sensor for the auto LCD brightness control is blocked or unblocked from ambient light, the LCD brightness remains the same. I am wondering if I have a dud or are there any other 5D3 owners seeing the same thing? Thanks

EOS Bodies / No Quick Menu in 5D3?
« on: April 07, 2012, 02:47:09 PM »
In my 5D2, I use the "set" button to access a quick menu for setting up a shot (aperture, iso, shutter speed, af mode, exposure mode, etc). Is there a way to set this up in 5D3? I can't find it in the manual. Thanks

EOS Bodies / Canon 5D3E?
« on: April 05, 2012, 11:43:48 AM »
It will be nice if Canon could come up with a 5D3E. A less stronger AA filter will increase the sharpness and level of detail in still shots, while sharpening videos as well. Moire and false color only affects a very small number of still shots and video footages, but should the majority of still shots/video footages not affected by moire/false color suffer for the sake of a stronger AA filter? What do you guys think?

EOS Bodies / Anti-aliasing filter in 1DX
« on: April 03, 2012, 10:07:19 PM »
Will the 1DX have a strong anti-aliasing filter (optical low-pass filter) as in the 5D3? Is there any indication of this?

EOS Bodies / 1DX sample RAW images

Hi, are there samples of RAW images from the 1DX available for download anywhere? Thanks

EOS Bodies / FEL in 5D3 and 1DX
« on: March 14, 2012, 08:49:47 PM »
Is the FEL (Flash Exposure Lock) linked to all the focussing points in the 5D3 and 1DX in manual exposure mode? Thanks

My question is whether my light modifiers for the 580EX2 (e.g. stofen diffuser, Rayflash ring light, etc) will also fit the flash head of the 600EX? Thanks!
