Hello everyone, So I really would like to get a macro lens. I was looking at Nikon's 60mm and 105mm lenses. I think I would rather go with the 105, so that I can also use it as a telephoto lens if need be. However, the 105 nikon is around $900-$1000. On the other hand, the sigma 105mm macro lens is about $500. I am curious to know the differences in picture quality between these two lenses. Can anyone comment or explain the differences? Also, am I correct in thinking that a macro lens such as the 105 can also be used as a telephoto lens, for landscape/nature shots?
