The Tamron 17-35mm f/2.8-4 Di OSD, which leaked out earlier this week is likely going to be officially announced by Monday, August 6, 2018 at the latest, and according to Nokishita, you will be able to preorder this new lens then.
Pricing on the lens is 78,300 yen including tax, which roughly converts to $700 USD. We’d expect this lens to come in at about $499 USD before tax for American buyers.
The Nikon version is slated to start shipping on September 4, 2018, there is no word on when the Canon version will begin shipping.
Tamron has had a string of good value lenses over the last couple of years, and we’d expect the 17-35mm f/2.8-4 Di OSD to continue the streak.
