Summary: I am using for comparison the Pentax 31mm f/1.8 fa limited lens, this may not be fair sense the Pentax is currently almost 4x more money, but I feel the Sigma compare quite well to this lens in image quality where it counts on a lens of this type the center is very sharp! I mostly use this for portraits and picture that I want a creamy brokah to give a picture a 3D pop and this lens delivers!
Summary: Producto 100% recomendable. Servicio rapido y confiable. Lente de muy buena calidad, buenos acabados. Profundidad de campo decente, nitidez muy buena. Enfoque normal para ser Sigma y no Nikon. Precio y calidad en su justa medida.
Excerpt: You need to have this in your bag! I bought this lens for a few main reasons. I wanted a really fast aperture for low-light conditions and a prime lens. The Sigma for me has it all. Its sharp, crisp and extremely quiet. Auto focus at f1.4 for me was a challenge at first. the more you use it the easier it becomes.
Pros: Consistent Output, Easily Interchangeable, Fast / accurate auto-focus, Great build quality, Great in Low Light, Nice Bokeh, Strong Construction
Great portrait lens. I love it - Read why the other reviews are lame.

Summary: I really wanted a good portrait lens to go with my kit. I have a 10-20, an 18-250 and a 50. The 50 was just too much as you had to walk halfway across the room to "zoom out" enough to get a good field of view. Because of this, I LOVE the 30 and gave the 50 to a friend and have never missed it for a second. The 1.4 is nice but it does get a minutely soft around the edges at 1.4 but at 1.6 it totally clears up. But read on and see why this doesn't matter...
Summary: It is better than Canon 50 mm F/1.4 for a crop DSLR, and it is much cheaper than Canon 35 mm F/1.4 L. There might be some mis-focus based on different samples. My first one has a misfocus ~1.5 cm when implanted on my Canon T2i. Then I returned it back and changed it into a new one. The second one is perfect.
Excerpt: Solid Image quality, and a much needed focal length for APS-C sensors. Focuses pretty quick, but not as quick as canon's USM. Great build quality. Highly recommended as a first prime to go with a standard Zoom. I use this alongside my Canon 15-85USM for low light situations, artsy bokeh up close, or when I want to carry around something a little lighter.<br /><br />Highly recommended.
Pros: Durable, Fast / accurate auto-focus, Nice Bokeh, Rugged, Strong Construction
