I've received my 200-400 mm f/4 Nikkor (AIS) a few days ago, and have been putting it through its paces. Would you believe this lens had been sitting idly on a shelf for 20 odd years? What a pity. To my eyes, it was in a pristine condition. Now of course it will be a working tool for me, so those innocent days will soon be gone :smile: It was quite cold today, around -15 C, and I found that I may have to clean the lens to remove the old lubricants, because 20 years of inactivity has made the focusing action rather stiff. Otherwise, the 200-400 performed to expectations. Below, my new acquisition put to some real work. The white stuff all around is snow, and the yellow contraption on top of the lens is my GPS unit. I shot a lot of snow landscapes today in a remote area outside Oslo, so having GPS to find my shooting locations afterwards is indispensable when I write image captions later. The D2X of course records GPS data in the EXIF header, so using GPS with this camera is a breeze.
