I purchased this lens to use with my Sony A57 (16.1 megapixel APS-C, 1.5x crop). I have three other Tamron SP lenses (A16, A005 and B01) and chose them because I felt their image quality was as good, maybe even better than the comparable Sony or Sigma lenses.

solid build; good fit & finish; very sharp at f/2.8-f/3.1 and tack sharp at f/3.5-f/16; no lateral chromatic aberration; no distortion; IF; quiet af; no front/back focus issues; smooth focus ring; moisture resistant; 6 yr warranty

a-mount connector a bit loose; sharpness declines after f/16; minor bokeh fringing from f/2.8-f/7.1; minor vignetting from f/2.8-f/3.5; lens flair; Sony version lacks VC; AF slower than expected; no case/pouch

As you might expect from a 90mm macro lens from Tamron, the optical performance of this lens is excellent. The lens delivers superb sharpness and contrast plus distortion, chromatic aberrations and falloff are kept in check also.
