Tamron 20-40mm f/2.8 Di III VXD Sony E camera lens bundle with 67mm UV filter and microfiber cleaning cloth

Compact wide-to-standard zoom

The Tamron 20-40mm f/2.8 Di III VXD is a full-frame Sony E-mount lens that covers an ultra-wide 20mm through a standard 40mm focal range. Its constant f/2.8 aperture and lightweight construction suit photographers who want a single lens for landscapes, cityscapes and environmental portraits without carrying multiple primes. The bundle adds a 67mm UV filter and a microfiber cleaning cloth for immediate protection and maintenance.

Sony E-mount AF practical limits

Autofocus is driven by Tamron's VXD linear motor, which delivers quiet, high-speed focusing for both stills and video on compatible Sony mirrorless bodies. The lens communicates fully with the camera's focus system, but performance will vary with the specific body's AF algorithms and firmware. Manual focus override is electronic, so the focus ring response depends on the camera's implementation rather than a direct mechanical link.

Close-focus capacity and magnification headroom

At the 20mm wide end the lens focuses down to a 6.7" minimum object distance, achieving a maximum magnification ratio of 1:3.8 for wide-angle macro work. This allows detailed close-ups of small subjects with expansive background context. Magnification decreases through the zoom range, so the 1:3.8 figure represents the closest working capability; tighter macro ratios require a dedicated macro optic.
