DX and FX lenses have the same crop factor - 1.5x - when used on a DX format camera. However, while DX lenses have a 1.5x crop factor on both DX and FX cameras, FX lenses only have the crop on DX cameras.
Your FX 50mm lens will have an angle of view equivalent to a 75mm lens when used on a DX camera and an angle of view of 50mm on an FX format camera. Your DX 18-105mm at 50mm focal length will have an angle of view equivalent to 75mm on both DX and FX format cameras.
The Nikon Lens Simulator helps to illustrate this by simulating the effect of lenses with different formats and focal lengths on both DX & FX format cameras. Visithttp://imaging.nikon.com/lineup/len...
