Heavy vignetting, soft in the corners, but it's a good little lens if you are looking for something on the wide end.

Great, Underrated lens!
There are a lot of bad reviews about this lens. It does have it's flaws, but overall it is great wide angle lens for the price. I was in the market for as wide of a lens as I could find around the $500 price mark. And this what I took a risk after reading multiple bad reviews.
