The Sigma AF 105mm f/2.8 EX macro DG is an excellent lens without any significant optical flaws. The resolution figures are excellent and neither distortions nor CAs nor vignetting is something to worry about. Similar to the Tamron or Tokina counterpart it is basically as good as the much higher priced Micro-Nikkor (the classic one, not the VR). The build quality feels very good although the implementation of the Dual-Focus mechanism isn’t really perfect. Regarding all the excellent lens alternatives in this segment it is quite difficult to select a favorite … but the good news is that there isn’t really a wrong choice. READ FULL REVIEW
