Summary: I found this lens for cheap and decided to give it a try. The focus is fast and works with my Nikon D3200. The motor is a bit noisy for my liking. For the ranges of this lens the animals are far enough away they don't seem to hear or mind the noise. The stabilization is great.
Summary: I am learning how to use this lens. I took it on a birding trip recently and was very pleased with it. It is very powerful and as a novice birder, I was able to obtain some amazing photos. I would recommend this lens to others.
