Not Top Notch, but Priced Well

Summary: If I could, I'd rate it at 3.5/5 stars - but don't personally believe it's quite a 4/5. I got this lens because I wanted an ultrawide on full frame. Here's where it performs best: low light shots, video, af speed, depth of field.
8 it allows such a beautiful bokeh around your subject

Summary: Incredible lens. Wide open at 1.8 it allows such a beautiful bokeh around your subject. I use it for interior shots of my furnished apartments and the width of this lens and wide f stop allow for some beautiful compositions.
Summary: Overall its a good lens. auto-focus is pretty crappy sometimes when you're trying to catch something fast. Loud autofocus when its on video mode, but manual focusing is pretty quiet and smooth. Pictures come out clear, get a good wide angle without distortion like a fish-eye lens.

Summary: This appears to be a very nice lens, but I'm a little disappointed to learn that it is not weather sealed. I purchased this lens specifically for photographing Northern Lights, so I'll have to take care when bringing this lens indoors from the cold.

Summary: I bought this lens strictly for shooting stars. Good (not great) value for the money. There aren't many wide lenses out there this fast. It works well for stars. I'm able to get 2 more stops of shutter speed compared to my f/2.8 lenses. A big plus in my opinion.
Summary: I was looking for a good, relatively inexpensive fast lens. I decided to give the Sigma a chance, and I'm glad I did! I was able to make some very nice night time shots that none of my zoom lenses would have ever imaged.
