A month after the first reports came out that a number of RF 70–200mm F2.8 lenses were having issues with front-focusing, Canon has released a firmware update to address the issue.
As promised two weeks ago, firmware version 1.0.6 fixes the issue wherein certain units would focus in front of the active AF point, especially at longer focal lengths. The firmware changelog reads:
‘Fixed a phenomenon when performing AF shooting to capture a subject at close-range with the focus distance approximately set to the Tele-end (200mm), the image may become slightly front-focused.’
Firmware version 1.0.6 is available to download for both macOS and Windows computers. If your lens already has firmware version 1.0.6 installed, there’s no need to update. You can check your lens’ firmware in your camera’s menu system.
