Description — Tamron 20-40mm f/2.8
The Tamron 20-40mm F/2.8 Di III VXD is a full-frame zoom lens for Sony E-mount mirrorless cameras, spanning a 20mm to 40mm focal length range with a constant f/2.8 maximum aperture. Its wide-angle coverage makes it a practical choice for landscapes, architecture, interiors, and environmental shooting, while the consistent f/2.8 aperture ensures predictable exposure and depth-of-field control across the zoom range. Weighing only 365g, it is a genuinely compact option for a fast full-frame zoom, well suited to photographers who travel light or shoot on the go.
The lens accepts 67mm filters and supports both autofocus and manual focus operation. It is worth noting that the lens offers no image stabilization, so handheld performance in low light will depend on the stabilization capabilities of the paired camera body. Designed as a zoom lens for the mirrorless camera system, the Tamron 20-40mm F/2.8 represents a compact wide-angle zoom choice for Sony full-frame shooters.
