Too noisy as a video lens

Excerpt: I thought I had heard great things about this lens, but perhaps it was a different Sigma lens. This one was too noisy for use with my 70d for video. It's a nice range, but that was my primary reason for getting it. I didn't test it too much with video, but I'll wait for the next version from Sigma, or look into other offerings.
Summary: This was my first non- Nikkor lens. I had done considerable research before I bought this lens. Everybody loved it, and I had hoped that it would enrich my photography experience. Unfortunately, my copy had an autofocus problem. It would focus behind the intended focal point. I did several tripod tests, because I really wanted to love this lens. Alas, it would not focus on the intended focal point on my D7000. I had to return it. No problems there from Amazon.
Summary: Units would not focus -- continuously hunted for focus, and if they did lock focus, it was in an out-of-focus condition. Tried on multiple camera bodies, also took to my local camera store. The store clerks and most of the on-line forums agreed this is usually a symptom of the lens having suffered a drop or other hard impact. I can't blame Sigma -- I've used their lens in the past and been pleased.
Excerpt: I purchased this Sigma as an alternative to a 16-35 f2.8 from Canon as I was able to buy lots more products for the same money (bags, cards etc). I mainly use the Sigma at night parties/events but gradually the focusing was very much hit and miss. I couple the sigma with a 7D and a 580ex II but when I go to take photos of people they have to wait sometimes over ten seconds for it to take a photo and when it does take, it is usually out of focus.
Excerpt: The good: it is light weight. The bad: it is not as sharp as it should be for a 2.8 lens. The ugly: the fact that I was anticipating a great lens from the reviews. Will stick with Nikon from here on out. Just got a Nikon 24-70mm f/2.8 and its everything it was promised to be. Excellent lens.
Excerpt: I really wanted to like this lens. I have Canon 17-40 f4 L, but got this for the extra stop. The lens arrived with spots, the focus ring was very hard. The image quality okay. I decided to return it.
Summary: I bought this camera used from Adorama. I thought this was a safe option because I assumed Adorama checked their used items really well. Well I was wrong. My copy of this lens does focus from the center going out to the right edge of the photography. I sent it to Sigma to have it supposedly fixed and they told me that it must be my camera because they couldn't find anything wrong with the lens.
Summary: Got this lens after lots of research suggested it to be better than the tamron and as good as the canon 17-55. Build quality seems good but AF leaves a lot to be desired. I found pictures to be less sharp than I had expected so I used my camera's AF microadjustment setting to correct it. Turned out at focal length of 50mm and 2.8 aperture I had to set microadjustment to -14 which I thought was a bit excessive.
Summary: I bought this lens to take photos of our newborn baby. I rented it beforehand along with another I wanted to try, and chose this one based on fast relatively quiet AF, adjustable zoom, fast enough aperture, and OS. My rental copy was perfect. no front or back focus issues on my D7000. However, I bought a copy from Amazon Warehouse, and it was defective out of the box. AF hunted and hunted, and was loud compared to my rental copy.
Excerpt: The copy I have bought last week has a AF calibration problem within the focal lengths of 17-28 mm. And it also performs some weird AF operation. So it is packed up and goes back tomorrow. AF sometimes fails when it's run from infinity to a close up subject. It focuses somewhere in between and confirms the AF. So it is not hunting or failing to focus. It does focus but not on the subject in the scene. I tried so many times and it did the same.
