Auto Focus not reliable

Summary: I have not been happy with the auto focus. I have used this lens with both a cannon T3 and a cannon 70D. The problem is it will no come into focus. I have contacted sigma asking if there is anything that can be done about this. I have not yet gotten a reply.
Summary: I would have loved it had the lens been the lens I ordered. It was a Nikon lens in a Sony box and it didn't fit my camera. I was truly disappointed. I had been watching the lens and it got to the price I could purchase it and then it wasn't the right lens.
Excerpt: I bought this Sigma 50-500 lens to use with my Nikon D7000. My Nikon 18-300 mm lens has consistently out shot the 50-500 lens even using it on a tripod. I have noticed I have to constantly adjust the D7000 fine tune from +3 to -13. I am currently trying to find my options right now..
Cons: Blurry Focus, Heavy, Inconsistent auto focus, Poor in Low Light, Slow Focus
Summary: I was really excited when I received this lens. I had rented one a few months ago and really liked it. After only using it a few times the autofocus quit working. Totally disappointed. I returned it.
Summary: Likes: Lens controls all work well and integrate properly with my Sony SLT-77. Autofocus works well and would even track flying birds. Dislikes: Every photo had soft focus at 500mm. I tried OS on/off, Sony steadyshot on/off, handheld, monopod, high quality tripod.
Summary: I purchased the lens with an intent to use it as a prime lens on my bird outings. One trip convinced me to rethink that and to use it only when set up with a tripod. This is a monster, carry this around for more than just a moment and your arm will ache.
Excerpt: I bought this lens two years ago and have used it heavily and also have some experience with other people who have bought the canon 100-400mm and direct comparison by borrowing their 100-400s. I use this lens for nature photography/birds and found some fairly serious issues with this lens.
Cons: Blurry Focus, Difficult to Clean, Lens Creep, Poor in Low Light, Poor Sharpness 250mm, Weak Casing
Excerpt: I shoot mostly nature and bird pics but also do some sporting events like college baseball. I admit the images are good but that's about all I can say after owning one for five months. Two months after I bought it the autofocus quit working.
Pros: Consistent Output
Cons: Fragile, Heavy, Poor in Low Light, Weak Casing
Summary: I loved my new lens. Everything was working well until about a week ago. I picked up the camera, turned it on and NOTHING! Moved the lens to a different camera body, still nothing. Tried a different lens on the original body and it worked fine. So disappointed!
Summary: I got this lens from an AD, not from Amazon. I fails totally to focus when zoomed beyond 200 mm. It will hunt for a long time and, either give up, or misfocus. I used it with my 400D. And for now i have used it for noting but shots of the moon using manual focus.
