Excerpt: Very nice lens, which I used on recent trip to Yellowstone. Good for close-ups however lens is noisy when focusing. I did not use it for video but therefore I cannot collaborate if you could hear it in video. Produces nice sharp pictures.
Excerpt: I bought this lens for nature photography, mostly animals but also birds. But then I found myself using it for portraits. It is a solid performer on all counts. The build quality seems excellent. Unless you are going to pay twice as much for the L lens your can't do better.
Pros: Consistent Output, Fast / accurate auto-focus, Lightweight, Strong Construction
