Tamron has announced the 12-20mm F2.8 (Model A084), a fast ultra-wide zoom for Sony E-mount and Nikon Z full-frame mirrorless. The number that matters is the wide end: 12mm on a full-frame sensor is a 122-degree diagonal field of view, and holding F2.8 across the whole range puts this lens directly at astrophotography and cramped-interior work. What makes the announcement worth a second look is the packaging. At 119.3mm long and 570g on the Sony mount, this is not the usual full-frame ultra-wide brick.

Tamron has confirmed a July 2, 2026 launch for the 17-70mm F/2.8 Di III-A VC RXD (Model B070) in Nikon Z and Canon RF mounts, bringing one of its most popular APS-C zooms to two systems that previously had no equivalent. The lens has been a fixture on Sony E and Fujifilm X bodies for years; the news here is the mounts, not the optics. For Canon shooters in particular, the wording in the release matters as much as the spec sheet.
