Tamron 17-28mm f/2.8 Di III RXD

A wide lens in more ways than one, the Tamron 17-28mm f/2.8 Di III RXD for Sony E-mount mirrorless cameras is a cracker

Digital Camera World Verdict

Cheap at half the price, the Tamron 17-28mm f/2.8 Di III RXD ultra-wide zoom with a wide f/2.8 constant aperture goes up against the likes of Sony’s G Master 16-35mm. It’s smaller, more lightweight, and beautifully balanced on an A7 or A9 camera body. However, it’s certainly not light on all-round performance and image quality, really punching above its weight. You need a good reason not to stick with own-brand Sony lenses, and the Tamron 17-28mm is exactly that.

Photographers with Sony A7 or A9 cameras who want an ultra-wide zoom will feel a natural pull towards the Sony Vario-Tessar T* FE 16-35mm F4 ZA OSS, which sells for just north of £/$1,000. For around twice the price, there’s the more exotic Sony FE 16-35mm f/2.8 G Master, which has a faster aperture rating but is comparatively big and heavy, weighing in at 680g. However, the Tamron 17-28mm f/2.8 Di III RXD matches the G Master with a constant-aperture f/2.8 design, but in a more compact and lightweight package, and at a much more affordable price.
