I understand that if you are talking about a VERY limited run, or the first batch or whatever, but man that doesn't make any more sense beyond the first week or two of release since Amazon has such a huge marketshare, and they obviously carry Tamron lenses. Of course there could be some behind the scenes dealings... hard to believe the unseen hand of market economics suddenly stopped working
Guess we will know in a few days haha
Yup. My personal (completely uninformed) guess is that Tamron's pre-orders from other retailers already covered every unit Tamron could make, and with higher margins than they would get from Amazon. I'm sure once the initial surge from early adopters buying from Adorama, B&H, Hunts, etc is over, Amazon will have them.
