I got it wrong yesterday but I am pretty sure I got it right today 🙂
Amazon Germany has the Walimex Pro 8mm f/3.5 Fish-Eye II lens for EF-S mount as Blitzangebot (Gold Box Deal) on sale at $269. The deal will go online at 14:30 Berlin time; Prime members can access the deal at 14:00. You can order the lens also from other EU countries.
Please note that the lens is for Canon’s APS-C DSLRs, the mount type is EF-S. The price will only be disclosed when the deal goes live.
I guess you can expect a price of €299. Regular price for this lens is €349.
