ok when you mean camera you mean the media 35 mm SLR digital cameras have comperable picture quality to slr cameras 10 mpix is just as good if not better than 35 mm some people feel that digital Photography is inpersonal that you can take 400 pictures in one day when in the world of 35 mm you were only limited to 31 snap shots in some cases.
The main difference between a digital camera and a regular camera is that a digital camera does not need film in order to work. The Canon A430 is inexpensive and a good starter digital camera. It's priced around $170 but will last you a long time.
You need to expand your question a bit more. Are you asking about the differences between digital vs. film? That question is being answered in other threads. OR.... Are you asking if you can convert a film camera to digital? The answer to that is yes, sometimes. Personally I would not recommend it, just go buy a digital camera.
No. You cannot economically convert a film camera to a digital camera. The digital system is very different and fitting it to an existing film camera is more expensive than buying a new digital camera. Some of the more expensive professional cameras can change between film and digital backs replacing the film transport with digital technology. The replacement backing includes all the electronics and controls typical of a digital camera of that caliber.
There is a difference between the Nikon camera and the Sony camera. The Nikon camera has more features and it is also wireless. The Sony camera is digital.
