Lens
The camera that is best used for crime scene photography is a single-lens reflex camera, also known as SLR. This camera allows you to use interchangeable lens.

no. its lens like glass for you to see far or near
There are a few camera lens types such as : a wide angle lens (used to capture a larger area than the area visible by a human eye), telephoto lens (opposite of wide angle), panoramic lens and so on.
No, this is a point & shoot camera and there is no lens mount. The lens is fixed on the camera and cannot be removed.
You can't. The lens on a Canon SD950 is integral to the camera body. Trying to remove it will ruin both the camera and the lens.
Yes. Nikon cameras have the distinct advantage over other cameras because they are backwards compatible with any Nikon lens. In short, any Nikon camera can mount any Nikon lens. The problem is how much of the lens capabilities are retained when used on a different camera. Depending on the lens' mounting system and the Nikon camera, the lens may or may not be able to autofocus or meter. Also, if you use an FX lens (from a film or D3/D700 camera) on a DX (digital DSLR) camera, the focal lengths will be different than on the film camera. More specifically, it will be 1.5 times the focal length of the film camera. (more zoomed in)

Basically most video cameras are fixed lens so you cannot put a camera lens in it unless it is specially built.
