Excerpt: The Sigma 50 EX has excellent image quality. Sharpness wide open is reasonable, becoming very good at f/2, and outstanding at f/2.8 and beyond.Vignetting is minimized for such a fast lens. Bokeh is best in class for f/1.4 lenses.Phase detect autofocus is an issue though and I don't believe it is tied to my camera body. Shoot near MFD and the lens will front focus. Shoot from maybe 5-15 feet with proper AFMA and the lens will focus properly.

Summary: I too wanted to love it. Chronic front focusing straight out of the gate. Love the build and the feel. But I didn't want to spend $50 shipping it in to fix a focus problem on a brand-new lens. And no, I did not have the multi point focus setting on. I never do. But it front focused about 1 inch, enough to not get the sharpness on the eyes that I'm looking for. The bokeh is really amazing, much better than the Canon version which I now own.
Summary: Well, I had high hopes for this lens. After reading countless reviews, I decided to get this lens rather than the Nikkor 50mm 1.4g. I read the horror stories about auto-focus issues thinking, "Oh, surely I won't get a bad copy of the lens. It'll be fine." I wish this were the case. My first copy of the lens was extremely front-focusing. Awful. I tried everything from single-point focus to trying a different camera entirely with no success.
Summary: This lens in THEORY is amazing. But in practice its just didn't live up. The lens had focus issues. It wasn't me. I'm no noob to the world of cameras and autofocus too. My other lenses focus just fine and I'm not a Nikon fan boy, I usually look for the best lens at the best price. Ended up returning the lens.
Excerpt: I wanted to love this lens. I have been in the market for a new 50 for a while and had the canon version at one point and sold it, and then regreted it. The first copy of this lens front focused so bad that I could not micro adjust it enough, and the second copy just would not focus on anything…BH is always great however so this review does not reflect their service. Simply on the lens.
Summary: I got this lens along with two Nikon lenses (35mm 1.8 and 85mm 1.8). I don't know if I got a defective one but the auto focus was fast but it would not lock onto subject well... It was also louder than the Nikon lenses. I suppose I learned a lesson and will not be be buying any off brand lenses anymore... When the auto focus got it right or I manually focused the images came out very nice.
Summary: After going back and forth with the "should I's" about getting a 50mm 1.4, I own the Nikon 1.8 and I love it but wanted to try out the 1.4, I decided on the Sigma based mainly on the price. It seemed just as good as the Nikon version on paper but boy was I wrong. I've had the lens for 1 week and all my test shots are really soft. I also tried calibrating with no success. Returning today but I'm not soured on the lens and have requested a replacement.
Excerpt: I really wanted to like this lens, it's beautiful on the camera. The build quality is definitely a step above the canon 50mm 1.4. The problem is that each shot you take with AF is a complete gamble. Depending on the distance from the object you are trying to focus on it experiences different problems. Relatively close and it front focuses, get a bit farther away and it back focuses. A problem that focus adjusting your camera wont solve.
2 tries, no luck. You should know what you might be getting into

Summary: I purchased this lens as an upgrade to my 50mm Canon 1.8 which I have had since the beginning and absolutely love. I purchased it having read the reviews and knowing about people getting a bad copy with focus issues. I thought I would take my chances and hope I get lucky. My first one arrived and I was immediately impressed with the design and the heft compared to my cheapo 50. Also the opening on this lens is massive compared to the canon.
