Today Sigma Japan launched a teaser for a new November 16 announcement. I am 100% sure this is related to the new Sigma 70-200mm f/2.8 (listed here at BH) . So they will “only” announce the full specs and pricing. According to my source this lens will go on sale on December 7 for €1699. That’s €200 more than the Tamron 70-180mm f/2.8 .
