Beautiful lens but not very sharp.

Excerpt: I bought it to replace my canon 1.8 metal mount from 90´, however is not as sharp and the autofocus is not that accurate as that old lens. The lens is beautiful, it feels solid and professional. The image quality is very good in the center and very bad in the corners of full frame. A lot of chromatic aberration. The big front element does its work very good because there is almost nothing of vignetting.
Excerpt: I received the lens from B&H in a well protected package. The lens took great pictures; however, it suffers from front focusing. Thank fully new lens' have warranties. I sent the lens to Sigma for calibration. They have calibrated the lens and it is on its way back. The whole process took only 2 weeks.
Pros: Durable, Nice Bokeh, Rugged, Strong Construction
Excerpt: I love everything about this lens aside from it's AF. If my subject is close to the camera, the AF front focuses. If the subject is further away, it back focuses. Unfortunately the AF is very unreliable at f/1.4, but aside from that, this lens is PERFECT. The bokeh is so absurdly smooth and nice looking, and the lens is sufficiently sharp.
Pros: Nice Bokeh, Strong Construction
Cons: Af Shift, Blurry Focus, Distance Related Af Shift
Excerpt: I used this lens to photograph my family and also tried it out on an engagement shoot. The quality of photos was good, except that it was consistently front-focusing. I later set up a test to confirm this and it does indeed have a front-focusing issue. This lens is also significantly larger and heavier than the Canon equivalent so I am exchanging for that lens instead.
Front Focused, had to add +20 MF adjustment on 5DM3

Summary: I had high hopes for this lens after purchasing a 35mm 1.4 Sigma Art lens which was spectacular. Long story short, it was front focused pretty bad and my first 30 test shots were all out of focus at 1.4. Got a calibration target and started tweaking the micro-focus adjustment. The max my camera goes is +20 and that yielded the best results. I was able to get it even sharper by using manual focus so I think if I could take it higher than +20 it might be even better.
Summary: While researching to buy a 50mm 1.4 i was confused between canon and sigma. I read mixed reviews about sigma and a lot of ppl complaining about front focus or back focus problem, I took a shot at it anyway so I won't have regrets. Here is my take about this lens Cons: 1) the focus really is a hit and miss. I never felt confident that I would get my photo sharp at selected focal point. 2) by no means it is a light or a small lens.
Summary: I really wanted to like this lens. It's solidly built and have a good weight to it. And just look at the size of the front glass element. But the AF had significant inconsistent back-focus issues that micro-adjustment could not fix. Maybe I could have sent the lens along with my camera to Sigma for fine tuning... but I do not possess that level of patience. I ended up returning the lens and bought the sigma 35mm f1.4 instead.
Excerpt: The build quality was good, I like the pinch lens cover. The image quality is not great. Bokeh is better than the Canon midrange 50mm but image quality was sleightly better with the Canon a hundred bucks cheaper. Cant beat Adoramas return policy, and customer service.
Excerpt: Unfortunately my copy proved impressive for all the wrong reasons. Once you get past the sturdy construction, the awesome 77mm front element and the nice weight of the lens, you're left to wonder why Sigma couldn't afford to hire some QC personnel. My copy was impossible to focus properly. I tried micro adjusting it without luck. The shots were not "soft" they were simply out of focus. There was also an incredible amount of CA throughout the frame.
Excerpt: I love everything about this lens except the focus. The build quality is great. I love the size and weight of the lens on my Canon 7D. The Bokeh is very smooth. But, the deal killer is inconsistent focus....even manual focus. The micro focus adjustment helped calibrate the lens to my camera but it still didn't fix the issue. I can take several shots in a row never moving the camera and most will be blurry or slightly to severely out of focus.
