Summary: I bought this lens with high hopes. Within 20 minutes I wanted to return it. Within 2 hours I had already gotten everything together to ship it back. The auto focus is absolute crap, I have a canon lens 50mm that cost $100 that focuses a million times better than this lens. It roams and roams and roams without focusing, during the roaming it jerks. It jerks so hard that it actually shakes my entire camera. I even have a $400 sigma that has never done this!
Summary: I ordered this lens because of the overall rating of the reviewers. I was aware of Sigma lens quality control issues, but wanted to try my luck. The first lens I received had pretty smooth auto-focusing. Given enough contrast and light, the lens seemed to focus well. However, I tried out the lens with the downloaded focustestchart, and found that this lens had back focusing problems which got progressively worse when the F-number was increased.
Excerpt: I have had to return this lens 4 times now to Adorama because they continue sending me copies that consistently back focus. This is a significant problems on a F1.4 lens where the depth of field is already paper thin. To the lens' credit, it is very sharp stopped down to 5.6 or so, when the back focusing issues are not as apparent.Adorama's customer support has been horrible and inconsistent with half the customer service agents assuring me that they would inspect the...

Summary: After 4 attempts now, I have given up on this lens. All of my copies with different serial number batches were plagued by back-focusing issues. The first copy was horrendous, focus was off by 2 feet shooting at a distance of just 15 feet. The other copies were still bad, but the focus seems to be off by about half as much. I am using these on a Nikon D90 where I have never had any focusing problems with any of my other 8 lenses, so i am hesitant to blame the camera.
Summary: Short version: I wouldn't buy a Sigma 85mm... I believe they underestimated the huge demand for the lens, and as a result, I think their quality-control couldn't keep-up. If you buy this lens, you have (IMO) a better-than-even chance that it will be at-least partially defective. Either it won't focus reliably, or it will front-focus or back-focus (all the time), OR worse still, it might be in the 10% that (to my recent experience) don't work at-all when you put it on...
Excerpt: Received my Sigma and was excited to do some senior pics. I chose it over the Canon due to much research about clarity and bokeh. I own, or have owned many L series Canon gear and thought this would stack up to them. One minute after I opened the package and put the lens on I knew I had a bad copy. I thought to myself " I thought I bought a lens, not a machine gun". The Sigma would not autfocus ..
Pros: Easily Interchangeable, Nice Bokeh, Sharp, Strong Construction
