Will a Nikon 35mm SLR film camera lens fit a Nikon digital camera?
Yes, if your camera has the detachable lens option (lens' are able to be removed from the base of the camera). All brands that are the same as your camera will fit.
A digital camera has a surface that it made up of many tiny electronic devices that produce signals when light coming in through the lens falls on them. These signals are recorded inside the camera. A 35mm film camera uses film as that surface. Film changes chemically when touched by light. This film is later removed from the camera and put in a chemical solution that makes it possible to see the image.
