Excerpt: I realize that one could spend a lot more for a telephoto lens, but as an amateur trying my hand at nature photography this was enough. It is quiet, and I have been satisfied with the images. I looked at Tamron and Sigma, but felt more comfortable putting a Sony lens on my Sony A-65.
Excerpt: Excellent value for money, can hunt for focus at times but pictures are sharp and over 85% are keepers. Took this on safari in South Africa and was extremely happy with the results. Cannot warrant paying 5 times or more for faster glass when I use it mostly outdoors.
