11-20mm f/2.8 Di III-A RXD

The Tamron 11-20mm f/2.8 Di III-A RXD is the best ultra-wide zoom available for Sony APS-C cameras — delivering a constant f/2.8 aperture across a 16.5–30mm full-frame equivalent range, in a compact and affordable package. Sharp from corner to corner even at 11mm, with quiet RXD AF and moisture resistance, it is the natural wide zoom companion for the Sony A6700.
