I recognize that the 1.5 crop factor for 35mm equivalency applies to the focal length of DX and FX lens when used on a DX camera body. But in macro photography the focal length relates to working distance. What about the magnification ratio for macro lenses? Nikon says the magnification ratio of the 85mm micro DX lens is 1:1 - I assume this applies when the lens is mounted on my D80 (DX) camera body. Nikon also says the 105 micro (FX) lens has a 1:1 ratio, which I assume applies to the lens mounted on a FX body. But if I mount the 105 micro on my D80, the APSC sensor only sees the center of the 1:1 image. Does the 1.5 crop factor apply to the magnification ratio?
