BTW, I finally figured out why the 200 of the 18-200 isn't the same as the 200 of the 70-200. It has nothing to do with FX versus DX, but the fact that zooms are measured when focused at infinity. And, higher power zooms tend to have less reach at the long end at shorter focal lengths. Thus, the 18-200 will have a full 200 when focused at infinity (and you'll get the same reach as with the 70-200), but when focused closer it behaves more like a 170 mm lens. Oh I am so so jealous….
