I'd like to get some common knowledge on what is the range of the magnification of a optic lens? Which company offors the best magnification?
Thanks in advance,

"Magnification" is a relative term. A camera puts a field of view onto a piece of film or imaging chip. The narrower the field of view, the higher the magnification of the camera.
Generally, the higher the focal length of a lens, the higher the magnification, and conversely, the lower the focal length, the lower the magnification or the wider the angle.
If you hold your hands straight out in front of you about 18 inches (45 cm) apart, that's about 45 degrees. On a 35mm film camera, a 50 mm lens, which is sort of a medium lens, will get you about 45 degrees. A 100 mm lens will get you about half that much, and a 25 mm lens will give you about a 90 degree view.
Since the size of film or chip varies from camera to camera, so you can't just compare focal lengths in the camera specs. For example, most digital SLR cameras have a 24mm chip, so a 50 mm lens has a field of about 30 degrees. Most point-and-shoot cameras have even smaller chips, and so the zoom is even higher. Therefore, a 15 to 70 mm zoom on a pocket camera might be the equivalent of a 40 to 160 mm zoom on a film camera, because the dimensions of the chip are smaller.
