Two defective units (now three!!)

Frank, Amazon

  • Summary: I bought this for my Nikon D7000 and specifically so I could photograph an upcoming indoor sports event my sons would be in. The first one arrived. Build quality seemed good. However, it would not autofocus - it would just hunt forever and never lock on. I exchanged it for another one which arrived the day before the event. It did exactly the same thing. Lighting levels were irrelevant, neither indoors nor bright outdoor sunlight would allow it to lock on.

Rolled the dice, but no luck...

  • Summary: The Sigma lens unit that I received does not auto-focus at all. As mentioned in many other 1-star reviews, the lens will hunt and hunt, sometimes for several seconds and stop out of focus, and other times would hunt endlessly. Both phase detect and contrast detect modes suffered from this defect on my Nikon D90. Manual focus works great, producing very sharp and clear images. The camera body used to test the lens works fine with two (2) other Nikon branded lenses.

Another defective copy

Amazon Customer, Amazon
16 November 2012
  • Summary: I knew about the quality control issues with this lens, but I took my chances and bought one hoping for a good copy. I received this lens yesterday and tried it all day with my Canon 7D. Unfortunately, this was another defective copy. The lens could not autofocus in any light condition, even outdoors in the sun. It hunts for a longtime, and then when it's done, still produces out of focus images.

Bought and returned the same day

Chris, Amazon

  • Summary: I ordered this item yesterday after going back and forth as to get this or the Nikon 17-55. This lens has some mixed reviews but I figured "why not?" Well, after paying the extra money for next day shipping, I attached it to my camera, focused on a subject and.....wait, no I didn't. Because this lens does not focus. It hunts...and hunts...and hunts. I could not get it to focus on a subject unless there was TONS of light in the room.

Would not focus

AV Tom, B&H Photo
23 June 2012
  • Excerpt: The specs and reviews looked good. Would not auto focus on my D7000. Continuous hunting back and forth. Boxed it up and returned it. No more Sigma lenses for me. Bought the Nikon 17-55 f2.8 instead. Twice the price of the Sigma but worth every penny. I gave the Sigma the lowest score. I give B&H a 5 for their easy return policy.
  • Pros: None
  • Cons: Would not focus

Poor quality, worse customer service

WXM, Amazon
25 February 2012
  • Summary: I was debating between this lens and Canon 17-55mm and decide to go with this one because of the price. My first mistake! The lens has some loose parts kind of noise from the begin. It is my first third party lens and I don't know what to expect as normal and have a couple of friends look at it, could not see obvious problem as it functions well. Decide to go along with it for the time being since it is covered under warranty. My second mistake!

No Quality Control

Mr. Family man, B&H Photo
20 March 2011
  • Excerpt: Looks Great nice specs. Pictures look great if taken real close up. Used with D-60. It is supposedly compatible with. No other info to say otherwise. [...]. I wish Sigma had some clear info. on incompatibility. I bought this for my father in-law. He sent the pictures and all were soft on anything off center only clear close up. Everything else was blurry and way off focus. For the money I don't see any advantages.
  • Pros: Strong Construction
  • Cons: Blurry Focus

Listed as Pentax - but actually selling a Nikon fit.

  • Summary: Listing is clearly for a Pentax lens, but when it arrived, they are actually selling Nikon-fit lenses, so returned for refund.

hält nicht was es verspricht

GWT, Amazon
25 November 2013
  • Summary: Das erste Objektiv war schlicht unscharf über den gesamten Bereich. Das zweite Objektiv hat eine leichte Fehlfokussierung. Bei beiden Objektiven wechselt in Verbindung mit meiner Kamera (Canon 60d) der AWB ständig. Die Haptik ist sehr gut, der Kontrast auch und die Farben angenehm ausgewogen. Kaum Flares und chromatische Aberationen.
