Conclusion: GET THIS LENS!
Review: I purchased one of these lenses a few months ago and I am in love with it. Not only is this lens a great macro lens with 1:1 capability, but this lens is a great all-purpose lens. My images always come out sharp and the color saturation and contrast is as good as it gets. This lens also has a very nice feel to it. It feels very solid and durable. Fabulous lens for the price.
