I've had this lens for 3 months and it takes OK photos but I'm not impressed by the sharpness. Yes I know it's reviews and its a jack of all focal lengths master of none. But I was reading Ken Rockwell's review of the 80-200 D lens and he wrote: "Three of four brand-new samples I inspected in December of 1999 had horrible manufacturing defects inside. I bought the only good sample I found. These defects were seen by performing a standard test used for inspecting used lenses: shine a bright light through the lens and look into the other end. This highlights any internal dirt, haze, scratches or bubbles in the lens that otherwise are usually invisible. I found internal haze on several elements and incompletely polished grinding marks left on the elements on all three defective samples I didn't buy. This is nasty; I have never seen this poor surface finish on any lens of any poor quality, including plastic elements on disposable cameras or garbage made in Russia or China. These defective lenses did produce great images, however I wanted nothing to do with this sloppiness and the problems I'd have explaining this if I ever go to sell the lens in ten years. Jeeze, there was more haze on the elements of the brand-new 80-200 AF-S than any of the 40 year old lenses I use with my large format cameras. The Tokina AF 80-200 f/2.8 I looked at to check my sanity was far better, too. I examined three USA versions and one gray market version at three different dealers in two different states, both mail-order and retail. They were all about as bad. I wonder if Nikon was reserving the good ones for the Japanese domestic market? Thank goodness I found a good one and that's the one I bought." Quotes originally found here So I look at my lens and it kind of looks like he describes. Obviously Nikon is trying to crank these babies out to clear up their backlog. Should I send it to Nikon and see what they say about it.If they say its ok I can just say send it back or pay them to clean it depending on the price. Theres lots of dust on the internal elements, especially up front on the inside and I have not abused it or had it in dusty environments. I can see some lens grinding marks on one of the elements. Can lens designs let dust in through the back? Otherwise can a camera store be paid to give an opinion on it and suggest recommendations.
