Class sharpness, excellent workmanship.

I photograph a lot of macros, with intermediate rings and lens attachments. As a macro lens I had hitherto always the Tamron 90 / 2.8 on a Pentax in Einatz. Last year I then took a change of system to Nikon. Since I was looking for a new macro lens. I had to test by acquaintances the opportunity the Tamron and the Nikkor 105. After I had made a lot of test shots, the decision was made in favor of the Sigma.

+ Best picture quality of all three lenses (and therefore buying decision)
+ High-quality workmanship
+ Best Value for money

The other writers criticized here loud Bildstabi I can not confirm. He can be heard, but definitely not overly loud or annoying. The AF is actually slightly slower than the Nikkor, but faster than the Tamron. But that you can live well. For me, at every lens alone the best picture quality buying decision, all possible drawbacks I take it gladly accept. Who benefits from a lens that is better in other details, but in the image quality can not keep up? At the end only the image counts.

But I can recommend this shard no questions. Clearly there are 5 star.
