I recently bought this lens and love it. Autofocus is fast, bokeh is good and i dont have to worry about flash. Paired with my D40 this setup is superlight! Check out
KenRockwell.com and see his review of the lens, people will have their opinions about him and his reviews, regardless, he shows a lot of images that he has taken of his children with this lens on a D40 and its obvious that it can produce some great images. You will love it with the D60, they make a great pair, and you cant argue with the price.
