I know that if I buy an FX/full frame lens for my Nikon DLSR with an APS-C sensor, then there's an approximately 1.5x crop factor applied, so that a 70-300MM FX lens attached to a DSLR would actually have a zoom range equivalent to about 105-450mm.
However, if I buy a 70-300mm DX format lens, which are specificly made for APS-C cameras, does the crop factor still apply (thus still producing a 105-450mm range), or is it a true 70-300mm?
