A beautiful lens that gives professional grade results.

Summary: Seriously, this lens is beautiful. I have played with so many 85mm lenses... Both of Canon's 1.2 L's, Canon's 1.8, the Rokinon (also beautiful, but manual focus), and this one. After testing Canon and Sigma's back and forth extensively, I just can't say that Canon's lives up to the price tag. It's true that this doesn't have the standout Canon red ring that screams "professional," but that's the only reason I would consider purchasing the Canon 1.2 over this one.
Excerpt: I received my Sigma 85 f/1.4 the day before Christmas, unpacked it and starting shooting at our family get together. I am very please hot the 85 mm works with my full frame 5D II. The 1st 20 shots or so was before my flash broke, then I was forced to go totally without flash and the 1.4 gave me the speed I needed to capture the moment I wanted,This is the 1st non Canon lens I bought in 20+ years and I am glad I did. Yes I would recommend to a friend.
Pros: Fast / accurate auto-focus, Nice Bokeh, Strong Construction
Summary: Oh my, this is an awesome lens for professional portraits, I use it for weddings in low light without a flash to capture ambient light and great detail, it`s very silent and very sharp, less chromatic aberration than some Canon`s prime lenses, This lens is one of my favorites and even shooting at 1.4 aperture is very sharp, read the reviews of it and you'll see what I'm talking about.
Summary: Easily the sharpest lens I own, or have ever owned, including Nikon 24-70 f2.8G, Tamron 24-70 f2.8 VC, Nikon 70-200 f2.8 VR1 and VR2, Nikon 50 f1.8 D and G, Tokina 11-16 and 12-28, and several other standard zooms and kit lenses. Even at f1.4 this thing is ridiculously sharp from edge to edge. Stop it down just a little and all 36.3 million pixels from my D810 are razor sharp, even the extreme corners at 100% magnification.
