Lens Tip published its full Tamron 17-50mm f/4 Di III VXD review and they have an interesting point of view. While I agree with Lens Tip that Tamron should be commended for its unique designs I do think that Tamron could have come in at a slightly better price point considering the compromises on full frame cameras. You can read the full review here or check out an excerpt below:

Pros:

  • good image quality in the frame centre across the whole focal length range,
  • decent image quality on the edge of the APS-C sensor,
  • negligible longitudinal chromatic aberration,
  • sensible correction of coma,
  • silent, quick, and accurate autofocus,
  • moderate vignetting on the APS-C sensor,
  • proper performance against bright light,
  • acceptable price/performance ratio,
  • negligible focus breathing.

Cons:

  • monstrous vignetting on full frame at 17 mm focal length,
  • weak image quality on the edge of full frame at 50 mm,
  • huge distortion at wide angles of view turning sometimes into moustache distortion,
  • some problems with spherical aberration.
