Tamron announced the 12-20mm F2.8, model A084, on July 15, 2026, for full-frame Sony E and Nikon Z cameras. Its combination of a 12mm wide end and an F2.8 maximum aperture across the zoom range is the central specification for photographers considering it for nightscapes.

The handling details differ slightly by mount. Tamron lists the Sony version at 570g and 119.3mm long, while the Nikon version is 585g and 121.3mm. The lens also has a built-in rear filter holder and a non-removable hood. Those are useful details to check when comparing a filter arrangement and packed dimensions with an existing kit. The specifications list the same 12mm to 20mm range for both mounts.

Tamron says its optical design corrects sagittal coma flare and reduces peripheral blur and colour fringing. Those statements explain the company’s pitch to astrophotographers; they do not constitute an independent assessment of stars at the frame edges. This report covers the announcement and specifications, rather than a field test.

The release scheduled the Sony version for July 30 and the Nikon version for August 27, 2026. These are the dates recorded in the original announcement, not a check of present stock. Current availability needs separate confirmation before a purchase.
