From Canon Singapore
Perhaps some good news, though I would still not treat this as 100% until we see the official response to the “light leak issue”.
From Ong Khiaw Seng from Canon Singapore
With reference to your question on whether Canon Singapore will recall the EOS 5D MK III due to the light leak issue, we wish to inform you that we will not. However we will contact you later this month to rectify this issue. Please leave us your contact number for our Service team to contact you.
Here's hoping the above remains true.
