Question: are nikon d lenses full frame?
Answer: The beauty of the Nikon 50mm f/1.8D is that it can be used on both a full frame (FX) and cropped sensor (DX) Nikon dSLR. On a Nikon DX camera, the focal length will be approximately 75mm, meaning the Nikon 50mm f/1.8D becomes a flattering portrait lens.
