They only sell to Australian customers as far as I know, but they are linked to a distributor which provides to many online grey sellers (as I am moving into the retail business, I won't name names). I have never had any issues with them and was also one of the first to get a 5D Mark III due to their fast turnaround and shipping.
I know of someone who purchased and received one last week, so they had stock at least as late as that.
yes. there's stock in HK of 5D3 bodies (and kits) and grey market never got short of these. We will be receiving some units next week so I will be able to check serials, but I am nearly sure that cameras will be affected. My HK guy said they just don't care and they are too busy to check. As a matter of fact it will take a while to clear the market from "defective"
units. I don't really think that Canon recalled them. Their policy will likely be "if customer complains we will offer a "fix".
