Well, order in Germany then. I still hope that the dealers here will learn at some point to offer fair introductory prices. Then maybe more people would pre-order.
You can find the lens here: Tamron AF 70-180mm F/2.8 Di III VXD G2 Sony FE (Sony E, full frame) Currently we do not have a confirmed delivery date. You can pre-order it or activate the notification function.
The price is already very low. It has never been much lower. At the beginning, the part cost an overpriced 1700 Stutz: https://www.toppreise.ch/preisvergleich/Objektive/TAMRON-70-180mm-F-2-8-Di-III-VXD-for-Sony-A056SF-p610780
On black Friday, there is a high probability that there will also be a Tamron promotion here or elsewhere.
The 810 grams are no problem at all for the bayonet.
@Haachamachama What is the "standard" landscape photography focal length? I'd be really interested to know.
Your calculation is wrong. When you add it on B&H you need to add as well the taxes. So there is a price about
Subtotal:$1,199.00
Shipping starting from $29.49
Duties & Taxes $226.90
Total$1,455.39
This is dollar. So after converting to CHF you have about 1411.- CHF. To this price you have to add the MWST in CH which will add another 7.7% to the price, including shipping -> 108.- CHF. So you get a total price of 1519.- CHF. Then post will charge you another custom fee about 15.- I remember -> 1534.- Yes it's still cheaper if you order it there. But personally I prefer to buy it locally and I don't have to be worried about after sale services. And I think this slight price difference is acceptable.
