Tamron 11-20mm f/2.8 Di III-A RXD - Sony E, Fujifilm X Mount

The Tamron 11-20mm f/2.8 Di III-A RXD is a fast, ultra-wide-angle zoom lens for APS-C mirrorless cameras, offering a 16.5-30mm equivalent field of view. Its constant f/2.8 aperture makes it well-suited for low-light architecture, interior, and landscape photography. The lens is remarkably compact and lightweight for its speed, featuring moisture-resistant construction and a Fluorine coating on the front element to repel water and oils. When inspecting a used copy, check for smooth movement of the zoom ring and ensure the autofocus is responsive and silent. SDS verifies that the lens is optically centred, as wide-angle zooms are sensitive to internal alignment issues. Inspect the mounting plate for wear and ensure the electrical contacts are clean. Check that the lens hood attaches securely and that the glass is free from fungus or internal haze.
