Summary: I rented this first to test it out and was blown away by the photos I was getting on my Canon 70D then purchased it immediately. Forget carry a bunch of lenses around. This is basically a bunch of primes in one. I ended up selling my 2 kit lenses, 40mm STM and 50mm f1.8 as this lens replaced them all. Just add good zoom lens to your arsenal and you have everything you need to take awesome photos!
Excerpt: This is a fantastic lens. The second you hold it in your hands you can feel the build quality is an A+. Its got some weight to it and feels well built. I mostly use it for taking photos of my children and the bokeh looks great with this lens, very smooth bokeh. I can't think of any flaws about the lens its worth every penny I paid for it. Some people might not like the weight but for me the weight just makes it feel like a solid piece of equipment.
Pros: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Nice Bokeh, Strong Construction
People say this is like three primes lenses in one

Summary: People say this is like three primes lenses in one. It is. The f/1.8 is not a gimmick. You can shoot wide open and your images are sharp and free of chromatic distortion. It is a big, heavy lens. But it takes beautiful photographs and lets you blur out backgrounds to perfection. It is also very sharp, much sharper than any kit lens. It has some competition, but it will see a lot of time on my A77ii body.
Excerpt: Using it with my 70D. A sister to my favorite 5O 1.2L - great bokeh, colors, contrast. RIP the old EF-S 17-55 2.8! A little too heavy for the movies, but tripod or even monopod needed anyway does the trick.
Pros: Fast / accurate auto-focus, Nice Bokeh, Rugged, Strong Construction
Excerpt: I've got the lens about a week ago. I was somewhat wary because I have heard some horror stories about the Sigma QA. Either I was lucky or there are some changes in the Sigma QA procedures but my lens worked perfectly right out of the box. Razor sharp, excellent contrast. The mechanics gives a feeling of a highest quality. I have not used it enough so far to give a final verdict but the first impression is very good.
Pros: Consistent Output, Excellent Mechanics, Fast, Fast / accurate auto-focus, Strong Construction
Excerpt: (Used on a Nikon d5200)So far, I'm loving this lens! I'm a portrait photographer, using mostly natural light, and all of my portrait sessions are outdoors. I have wanted to be able to do more lifestyle/photojournalism style, indoor, family sessions. (Think Kirsten Lewis.) I also have three young kids of my own.
