I have used the Nikon 105 f/4 Macro since film only days. Got the Sigma 105 f/2.8 a few years ago, and later, got the Sigma 180 f/2.8, because I was so pleased with the results I was getting with the Sigma 105. The Sigma 180 allowed me to have more space between 'shy' subjects and camera, plus, the lens had a tripod mount on the barrel. (very useful). Have been pleased with the quality of images with Sigma lenses.
