Tamron 17-28mm F/2.8 Di III RXD – Verdict

Until now, Sony full-frame mirrorless users looking for a compact wideangle zoom have had one obvious option, the Sony 16-35mm f/4. But with the 17-28mm f/2.8, Tamron has delivered an exceptionally strong alternative. Like its 28-75mm sibling, this is a very likeable lens that combines impressive sharpness with a fast maximum aperture in a compact, lightweight, weather-resistant design. Landscape photographers in particular should appreciate its finely judged combination of strengths.

Tamron’s 17-28mm f/2.8 is a really excellent lens

Indeed given the excellence of its optical quality, the only real question mark comes over its limited zoom range. This is a lens that really needs to be paired with a 24mm or 28mm standard zoom for everyday shooting, whereas some photographers might be just about happy carrying the Sony 16-35mm f/4 on its own.

But in every other respect, the Tamron 17-28mm f/2.8 is an excellent alternative that offers fantastic value for money. Let’s hope the firm can produce Canon RF and Nikon Z-mount versions for those firms’ full-frame mirrorless cameras sooner rather than later.
