Having fallen in love with my 50mm I am looking to add a another prime to my collection. Currently I am considering this
Sigma 105 2.8 or an older used
AF Micro-Nikkor 105mm f/2.8D . Primarily I will be using these to photograph live performances, but will also be used on the side for macro work. I am a big fan of Nikkor glass, and would like to know if anyone has used the Sigma 105. It would be nice to have a brand new lens, but sticking with native glass is my personal preference.
