What Buyers Say

Tamron Di III-A 17-70mm F/2.8 Di III-A VC RXD

85 out of 100 high confidence 62 reviews

The Tamron 17-70mm f/2.8 Di III-A VC RXD lens is widely praised for its sharpness, versatile zoom range, constant aperture, and effective stabilization, making it an excellent all-around lens for APS-C cameras. Users appreciate its solid build quality and value for money, though many note it is noticeably heavier and larger than typical kit lenses, which can feel unbalanced on smaller camera bodies. A few reviewers mention minor issues like chromatic aberration at the longer end and noise from the aperture blades at certain settings, but overall sentiment is very positive.

Pros
  • sharp image quality across zoom range
  • constant f/2.8 aperture
  • effective image stabilization
  • fast and quiet autofocus
  • versatile 17-70mm focal range
Cons
  • heavy and large for APS-C body
  • chromatic aberration at 50-70mm
  • aperture blade noise above f/5.6
  • short zoom throw initially stiff
  • no aperture ring on Fuji version
