This Lens Is Not Sharp

Summary: I tried two copies of this lens and was very disappointed, it was not sharp on the edges or corners when shot wide open at any focal length. I would not recommend this lens for professional use.
Summary: Buy this if you want BLURRY, OUT-OF-FOCUS, and NOT SHARP pictures! Maybe I got a dud but I HATED this lens. I probably got 20% of my pictures in focus. Used with a Nikon D5100 and tried all variations of settings, lightings, environments. I'm not the best photog but I'm certainly educated enough and know when I have a crappy lens... that was this one. Just awful. Best part of this transaction: Amazon refunding my money.
Excerpt: I have the Sigma 70-200 f/2.8 and have had no issues with it for the 7 years I've used it, so I had no hesitation in picking up this Sigma 24-70 f/2.8 - but after receiving it, I only got 57 photos out of the lens before the lens stopped focusing (it would not focus in either the auto or manual focus modes). I have to give the lens I received a rating of 1 star (I know Sigma makes quality stuff - I just happened to not have received one of the quality ones that worked).
Excerpt: The lens felt solid and balanced well with my D7000 but I could not get good results with my D7000. The focus was hit and miss but mainly miss. I contacted Sigma directly after I returned the first lens to Adorama but they weren't much help. I sent the tech several photos as examples but he said he thought it must be the camera.
Excerpt: Big disappointment! I tested this lens both indoors as well as outdoors and could not get a sharp image at any range or aperture. My first time buying a non-L lens and will be my last. Maybe I got a really bad copy but I am not taking a chance in getting another one. Will need to dig deeper into my pocket to get a Canon "L" lens instead.
Excerpt: I purchased this lens earlier this year along with the 70-200mm. Primary usage was for portraits (people and pets) and for event photography like wedding receptions and parties. Compared to the more expensive Nikon, the 24-70 is not as sharp although to the average viewer, it is not barely noticeable. For the $$$, I was satisfied with its performance. More concerning was what happened this past Saturday while shooting an event. The zoom ring stuck between 24 and 35mm.
Excerpt: See "Front Focus" by Rick on 3/2/10. I had the same problems, but sigma told me to use a ruler at 45 degrees and send them the lens and pictures. I did and still have the same problem. I don't have time to try to to do exchanges. I am hoping I can send it back and buy the more expensive Nikon. If you buy the lens, test it out on a ruler about 1 meter away, wide open, and at different ranges.
Pros: Durable, Easily Interchangeable, Rugged, Strong Construction
Excerpt: I purchased this lens along with a Nikkor 70-200mm F/2.8. I decided to purchase the Sigma because I own the Bigma, a superb lens for the money and to save some money on this large purchase. I took some shots at wide open aperture F/2.8 at 70mm the same day I received the lens to give it the acid test. I notice the images were not very sharp. So I took close-ups at full aperture and noticed more than softness, in my opinion slightly out of focus.
Excerpt: I wish I could give this lens no stars. Let me take you through the initial two months of ownership of this "so-called Professional" lens. I purchased the lens on September 29th and clicked it on my d700, aimed at my daughter and pressed the af-on button....nothing. I take the lens off the camera, click it back on again, aim and once again nothing. I call Sigma, they say i have to send it back to the repair facility and it takes 3-4 weeks to be returned to me.
Summary: i really wanted to like this lens. I had just upgraded to the d700 and need a full frame normal zoom. I was hoping to find a lower priced alternative to the Nikon 24-70. I had read some outstanding reviews and had high expectations. Got the first one, major focus issues that couldn't even be corrected with AF fine tune. Sent it back. Second copy, seemed to focus alright except it front focused at 70mm.
