11. Summary

Pros:

  • solid, sealed casing,
  • excellent image quality in the frame centre,
  • sensible image quality on the edge of the APS-C/DX sensor,
  • lack of problems with longitudinal chromatic aberration,
  • slight lateral chromatic aberration,
  • moderate astigmatism,
  • low vignetting on the APS-C/DX sensor,
  • excellent performance against bright light,
  • silent and accurate autofocus,
  • 5-year warranty period,
  • good price-performance ratio.

Cons:

  • too weak resolution on the edge of full frame,
  • huge vignetting on full frame,
  • noticeable problems with coma correction.
Despite a big difference in price when compared to the Tamron SPAF 28–75mm f/2.8 XRDiLD Aspherical (IF) MACRO I think the Tamron 28–75mm f/2.8 DiIIIRXD will be able to repeat the market success of that older lens designed for reflex cameras. It has very good optical properties – especially an excellent image quality in the frame centre and practically across the whole focal range. At the same time the new Tamron remains cheaper than products of Sony and Zeiss, offering a similar focal range. You can say even more: it is a dozen or so percent cheaper than the slower Vario-Tessar T* FE 24-70 mm f/4 ZA OSS.

The Sony company keep older models of their full frame mirrorless cameras on the market for a long time so their prices have been falling to levels acceptable for amateur photographers. Such amateurs might become interesting in supplying their bodies with reasonably priced lenses. The Tamron 28–75mm f/2.8 DiIIIRXD fits that scenario pretty well so I suppose it might be very successful and its owners – very happy with the results it provides.
