Summary: This lens did not meet my expectations of being better than my kit lens, Nikon 18-55mm. It was very slow to focus and many pictures came out blurry. I expected it to do better in lower light situations like indoors. Also the color in the pictures was off.
Summary: BEWARE THIS LENS ITS JUNK. FIRST OF ALL ITS SUPPOSED TO BE AN F/2.8 LENS WHICH MEANS IT SHOULD BE FAST AND GOOD FOR PORTRAITS. WELL ITS FOCUSING IS LOUSY AND ITS NOT FAST. ADORAMA SAYS ITS NEW BUT THEY SHIPPED IT TO ME IN SOME REGULAR BOX WITH MANUALS WHICH AM NOT EVEN SURE BELONGS TO THE CAMERA.
Summary: I've tried three copies of this lens. Two from Amazon. Both have significant front focus problems between 30-50mm focal length. It makes the close up "macro" functionality useless. Portraits at f/2.8 are useless because nothing looks like it's in focus.
The Faulty lens Sigma 18-50 F2.8 EX DC HSM Macro Lens

Summary: I bought this lens last week and I received today. Generally, Sigma lens has good optical function and good price. But If you get good condition brand new sigma lens, that will be great. Bye the way, it is very hard that you can get that condition brand new lens.
Summary: Well, I was excited about the review comparrisons between this, the Canon EF-S 17-85mm, and the Tameron equivalent. It was supposed to be very high sharpness, and nice bokeh compared to canon and just better all around than Tameron.
Summary: I liked the photos I took with this lens. THe macro is just fantastic. After a week I started having problems when the camera would not fire and the display would show F-- . The lens metal connectors were not sitting right on the camera connectors.
Summary: I got my copy a couple weeks back. Whenever I used the autofocus feature, the photos look quite blurry comparing to my 50mm/1.8 prime lens. Amazon has been very good in its customer service and sent me another copy right away, without charging me.
Summary: Die Lieferung ging schnell , verpackt war die Ware auch toll und äußerlich sah es nicht gebraucht aus. Was die Qualität der Fotos angeht, muss ich sagen bin ich maßlos enttäuscht. Wenn man scharfe Bilder machen will, kann man Sigma vergessen.
