I just got a Nikon D1 to play around with, and a couple of people said that because its a "full frame" camera, a 50mm lens is just that: 50mm. Other say a 50mm becomes appx 75mm because of the "crop factor". I never thought about it, so, WHO is correct ? thanks/respects, mike

The D1 uses a DX sensor which is smaller than FX sensor (or 35mm film) and thus has a "Crop Factor" of 1.5, Field of View (FOV) is another term relating to the same subject.
you can learn all about it at
Nikon did not introduce a Full Frame (FX) sensor until the advent of the D3.
Hope this helps

The focal length of the lens never changes. A 50mm lens is a 50mm lens regardless of sensor size.
The D1 and D2 series bodies have DX sensors. Since the DX sensor is smaller than a "full frame" (FX) sensor, a 50mm lens on the D1 will have the Equivalent Field of View as a 75mm lens on an FX or 35mm Film body.
Good Luck and Enjoy your Nikons!
