Digital Camera World Verdict

Designed for Sony’s APS-C format, E-mount mirrorless cameras, the Tamron 11-20mm delivers an extensively wide-angle zoom range, equivalent to 16.5-30mm in full-frame terms. It combines this with a relatively fast and constant f/2.8 aperture, further extending the versatility of the lens. Build quality and handling are very good. The lens features weather-seals and comes with a bayonet-fit petal-shaped hood. Autofocus is fast and virtually silent and image quality is highly impressive, although there’s no optical image stabilizer and the Tamron is pretty pricey.

The Tamron 11-20mm F/2.8 Di III-A RXD is billed as the world’s first 11-20mm f/2.8 zoom lens. That’s certainly true in the context of Sony E-mount APS-C format mirrorless cameras but Tokina launched its AT-X 11-20 F2.8 PRO DX with an identical zoom range and aperture rating for DSLRs a year earlier, back in the summer of 2020. Either way, The Tamron lens is significantly smaller and more lightweight, weighing just 335g and having a 67mm filter attachment thread, compared with 560g and 82mm for the Tokina.

The zoom range is equivalent to 16.5-30mm in full-frame terms, great for landscape and architectural photography. The lightweight construction is similarly ideal if you’re trekking into the hills or pounding the streets in search of these kinds of shots. The fast f/2.8 aperture (at least for a zoom lens) also makes the Tamron useful for shooting interiors or freezing action in low lighting conditions, as well as for astrophotography.
