Dear Business Partner,
Re: EOS-1D Mark III – Quality Issue
We would like to make you aware that we have concluded that there is a quality issue with some EOS-1D
Mark III units in the market. The problem can be linked to the adjustment of the AF Sub Mirror, and we
believe that this affects only a minority of units in the market at this time.
The phenomenon resulting from this problem (especially in high temperature) is that the optimal focus
point is uncertain in AI servo mode, or that the tracking performance of AI Servo is not accurate.
Regarding the products that have been sold to consumers, we are currently preparing a resolution for this
issue and will inform you of further detailed information and required steps through our official website at
the end of October or the beginning of November. Canon will accept these units for repair, but we will not
be offering an exchange or return.
In order to ensure that the customer experience is not damaged, and as a responsible company, Canon has
decided to stop the shipment of all EOS-1D Mark III. We would therefore like to collect all unsold EOS-1D
