Excerpt: I use this lens mostly for wildlife. Birds and Horses and animals that easily shy away. For the price of this lens, it has unbelievable sharp focus. Picture quality is as good as I would want. It is very light.
Excerpt: My work sometimes requires me to shoot rock concerts from the photo pit, and while my other 3 lenses (a Tokina UWA, and Nikon "50mm" and short zoom) have been fine, I wanted a longer zoom.
Pros: Consistent Output, Fast / accurate auto-focus, Lightweight
