You'll undoudbtedly hear about how sharp and awesome this lens is, as well as the weight. But what you won't hear about is its ergonomics! You can rest your thumb and middle finger on the zoom ring and be able to manually focus with your index finger AT THE SAME TIME. Not even Canon's lens can do this with as much ease as Nikon! For this, it is totally worth the price you pay (from a discount retailer of course).
