Digital Camera World Verdict

There’s an f/2.8 sized hole in the ‘affordable’ range of Sony own-brand lenses for its full-frame E-mount cameras. That’s neatly filled by the Tamron 28-75mm f/2.8 Di III RXD lens, which delivers fabulous image quality, has great handling characteristics, and is comfortably compact and lightweight. It’s tailor-made for Sony’s mirrorless full-frame bodies and is hard to beat, at any price.

The Tamron 28-75mm f/2.8 Di III RXD is a welcome addition to the Sony mount lens market. This is because, while the Sony FE 28-70mm f/3.5-5.6 OSS is a top-seller, it’s widely bundled as a kit lens with A7-series cameras. It’s certainly small and lightweight but the aperture shrinks to a disappointing f/5.6 at the long end of the zoom range, and it delivers lacklustre sharpness away from the central region of the frame. If you want to step up to an own-brand Sony standard zoom with a fast and constant f/2.8 aperture, you’ll need to invest in the mighty FE 24-70mm f/2.8 G Master, which costs around £1,800/$2,200 and weighs nearly a kilogram, negating the advantage of a slimline, lightweight mirrorless camera. That sets the stage perfectly for this class act from Tamron.
