[QUOTE="PapaST, post: 442784, member: 8330"] The 1.5 crop factor had me a little confused when I was first learning about FX vs DX. I'm taking a wild guess that you felt (from your reasoning of the 1.5 crop factor) that the 200mm FX lens should come out to be about the same FOV as the 300mm DX lens. Is that what you were trying to say? If so, it's a common mistake for some folks to assume the DX designation on lenses "factors" in the crop factor. But that's not true. 300mm is 300mm is 300mm etc. The DX designation more or less tells the photographer that the projected image from the lens will not cover an entire FX sensor. [/QUOTE]
