The Tamron 16-50mm f/2.8 A (Model B091) is a new constant-aperture standard zoom for APS-C mirrorless cameras that costs $529 to $549 at launch. The Sony E and Canon RF versions go on sale October 29, 2026, followed by Nikon Z on November 19 and Fujifilm X on December 17.
Tamron announced the lens on October 14. It's notable for arriving on four mounts at once and for being unusually light for an f/2.8 zoom, at about 305 grams. Tamron is also the subject of a bigger corporate story this year; see Sony's bid for Tamron.

Who is the Tamron 16-50mm f/2.8 for?
It's built as an everyday "go-to" zoom: wide enough at 16mm for landscapes, architecture and group shots, long enough at 50mm for casual portraits. Tamron also highlights video use.
The draw for Canon and Nikon APS-C shooters is especially big, because both systems have had few fast, affordable third-party standard zooms. Fujifilm users get it last, in December.
What are the trade-offs?
- No optical stabilization: rely on in-body IBIS, if your camera has it.
- Depth of field: f/2.8 on APS-C gives roughly the background blur of f/4 on full frame at the same framing, as Fstoppers notes.
- Shorter reach: it stops at a 75mm equivalent, so you'll need a telephoto for distant subjects.
How does it compare with Tamron's 17-70mm f/2.8?
The older 17-70mm f/2.8 Di III-A VC RXD reaches further and has optical stabilization, but it's larger and heavier. The new 16-50mm trades reach for a wider start, lighter weight and a smaller 55mm filter thread.
