Tamron 16-50mm f/2.8 Brings a Constant-Aperture Standard Zoom to APS-C From $529
The 305g lens covers 24-75mm equivalent at a fixed f/2.8, arrives first for Sony E and Canon RF on October 29, and reaches Fujifilm X only in December.
Tamron has announced a small, fast standard zoom for APS-C mirrorless cameras. The 16-50mm F2.8 A (Model B091) was announced on October 14, with Sony E and Canon RF versions arriving on October 29 at $529 and $549 (PetaPixel, DPReview press release).
The headline specs
The lens holds f/2.8 across its whole range from a 16mm wide end. On Sony E, Nikon Z and Fujifilm X bodies that equals roughly 24-75mm in full-frame terms, and Canon's larger crop factor gives 25.6-80mm. Tamron lists 14 elements in 10 groups, a minimum aperture of f/16 and seven circular aperture blades. The filter thread is 55mm on every version.
Close focus is 0.15m at the wide end and 0.29m at 50mm, with maximum magnification of 1:4.5 and 1:4.8 respectively. Length runs from 77.6mm on Canon to 81.6mm on Nikon.

Autofocus, build and video
Focusing uses Tamron's VXD linear motor, which the company describes as fast, precise and quiet. The lens has simple splash-proof construction, a fluorine coating and a metal barrel, and ships with a flower-shaped hood. Tamron does not list optical image stabilisation, so shooters on bodies without in-body stabilisation should check what their camera offers.
Support for the TAMRON Lens Utility software depends on the mount: Sony E and Nikon Z are supported, Canon RF gets firmware updates only, and Fujifilm X is not compatible.
Where it fits
A constant f/2.8 on APS-C is useful for events, portraits and indoor video, because most kit zooms narrow their maximum aperture toward the long end. Tamron has published MTF charts for 16mm and 50mm, but independent sharpness tests do not exist yet, and distortion and vignetting correction will depend on each camera's built-in profiles. Without optical stabilisation, handheld video relies on the camera body.
What to watch next
Reviews when Sony E and Canon RF units ship on October 29, especially corner sharpness at 16mm and focus breathing in video, and prices outside North America.
