Tamron’s 17-70mm F2.8 III-A VC RXD is a lightweight zoom for Sony APS-C E-mount shooters. Equivalent to a 25-105mm F4 in full-frame terms, this lens handles nicely on a6000-series cameras and offers great versatility for daylight shooting. Fast to focus, it also produces nice, sharp images across the frame and focal length.
Please note that Tamron only appears to ‘bake in’ chromatic aberration correction into files shot with this lens. As such, distortion correction (and vignetting, for that matter) is the responsibility of the end-user. As you’ll see in this gallery, you will need to correct for some fair degree of visually distracting barrel and pincushion distortion on the wide and mid- to tele- ends of the zoom ranges, respectively.
