Title: Incredible Lens
Review: I was expecting a great deal from this lens, and it exceeded all of my expectations.The build quality is top-notch; everything feels rock-solid and the focus ring is very smooth.Image quality is out-of-this-world. This is definitely one of the best-performing lenses in Canon's line-up, period. Color rendition is superb, contrast is excellent, and the sharpness is simply stunning. I don't think there is a sharper Canon lens under $6000.I would list downsides of this lens, but I really can't find any. If you need a high-quality fast telephoto, this is one of the best options available.
