What is the scale of fx format?

FX format refers to lenses that can be applied to full-frame SLR, such as D3 series, D700, D800/D800E. At the same time, FX frame lens can also be used in APS-C camera, but it needs to be multiplied by the conversion coefficient of x 1.5 to get the equivalent focal length, such as AF-S50/1.4g. The equivalent focal length is 50mm in D3s and 75mm in D300s.
