Last week after waiting for almost six weeks I received my Nikon AF-S 24-70mm f/2.8G ED. After many years of using various Nikon lenses this is the first lens that does not have a smooth action when turning the zoom ring over it's full range. Unfortunately I had to drive over 50 miles to collect it and did not think of trying it at the point of purchase. I did contact my supplier about my concerns and they were unable to confirm if this stiffness was correct or not. He has now other lens to check against, and possible will not have any more for several weeks. Has and member of this form purchase one of these lenses? If so can you help with your experience. The lens is smooth between 24-27mm, and between about 48-52mm. All other areas are considerable stiffer. This does not seem correct to me.
