Here are several test shots from the new Tamron 150-600mm lens shot on my Nikon D7000. Overcast for most of the day, but I was very excited to get out and run the new lens through its paces. The Ultrasonic Silent Drive is truly quiet. This is good and bad, sometimes its hard to tell if the lens is doing its job or not. While my first shot outdoors yesterday was of a soaring Turkey Vulture, this lens will take some getting used to for birds in flight. With 450mm of range, there is a lot of lens to search through before finding the target. Once it finds the target - very happy results so far.
