Tamron 20-40mm f/2.8 Di III VXD Sony E-Mount Camcorder Lens

Compact full-frame zoom for Sony E-mount

The Tamron 20-40mm f/2.8 Di III VXD is a fast-aperture standard zoom built for Sony E-mount full-frame mirrorless cameras. It covers a 20-40mm focal range with a constant f/2.8 aperture across the zoom. The optical design uses 12 elements in 11 groups to deliver high image quality in a compact, lightweight body. The VXD linear motor provides fast, precise autofocus performance.

Macro capability and utility software extend use

At the wide end the lens focuses down to 0.17 m (6.7 in) for a maximum magnification ratio of 1:3.8, enabling close-up work beyond typical standard zooms. TAMRON Lens Utility software allows owners to customise the focus ring function and apply firmware updates directly from a computer. These features add creative flexibility for both stills and video without extra accessories.

Suits creators needing a light.

This lens fits photographers and videographers who want a constant f/2.8 aperture from ultra-wide to normal focal lengths in a small package. The close-focusing ability helps with detail shots and wide-background self-portraits. Buyers who need telephoto reach, longer macro working distances, or a wider maximum aperture should look at other options.
