[QUOTE="Greywoulf, post: 2394, member: 636"] Well, that's not quite true..? Using an FX lens on an FX camera is where you get the complete true focal length image on the sensor and card. However If you use it on a DX camera you will get a cropped image that also appears to be telephoto enlarged 1.5X, just exactly the same way a DX lens works on a DX camera! So if you use an FX style f1.8 50mm lens on a DX camera you will actually be getting a magnified focal length of 1.5x, which = 75mm. And likewise an FX 85mm on a DX camera will give you128mm, and a 105mm will give you 158mm! [/QUOTE]
