Digital Camera World Verdict

The Tamron 17-70mm delivers a sizeable sweep of wide-angle to short telephoto focal lengths, all with an f/2.8 aperture. That’s quick for lens with such a large zoom range, making it an attractive proposition for APS-C format Sony E and Fujifilm X mount cameras. It also adds optical image stabilization and delivers good performance with very pleasing image quality, while featuring a tough yet lightweight and weather-resistant construction. All in all, it’s a very good buy at the price.

Mount the Tamron 17-70mm F/2.8 Di III-A VC RXD on an APS-C format Sony E-mount mirrorless body and has an effective zoom range of 25.5-105mm. That’s very similar to using the highly popular Sony FE 24-105mm f/4 G OSS on a full-frame camera, but with the added bonus that the Tamron’s constant aperture rating is a full f/stop faster. Naturally, you get the same effective zoom range with the Fujifilm X-mount version of the lens.
