DISAPPOINTING QUALITY CONTROL
9 November 2012
Summary: Purchased lens as an upgrade to Nikon's latest 105mm Micro-Nikkor with image stabilization and Nano crystal coating when I traded my D300 for the new D800 full-frame. The professional reviewers I read unanimously reported the lens as delivering exceptional image quality with the only detractions being the hefty weight and a significant cost increase over its non-stabilized predecessor.
Summary: I'm returning my lens for an exchange -- I'll update this review after I get the new lens. There are 3 major flaws that make my copy of the lens unusable. This is with the Nikon mount on a D800. 1. Focus "drift": Inconsistently, after attaining focus, the focus would drift slightly making the target out of focus. 2. AF malfunction: Sometimes the AF works great. Other times it does not work at all.
Summary: I purchased this lens about a week ago. I have not had the opportunity to shoot many pictures with it but from the first time I tried it the Auto Focus failed to work with the shutter button. It does focus (fairly accurately) with the AF button on my Canon 40D. I contacted Sigma and after 4 days they had not given me an answer. I wrote again and the reply I got was that maybe because the 40D was a new Canon model the engineers had not taken some adjustments into account.
Dieses Objektiv hätte eigentlich fünf Sterne verdient. Funktionier ader nicht immer deshalb nur drei.

Summary: Av und Manuel Einstellung blockiert manchmal. Objetiv Schelle lösen und gerade so festschrauben das es sich nicht von selbst dreht dann klapts für ne Weile. Habe jetz schon das zweite das die selbe Macke hatt.
