shooting video on the Panasonic GH2

I just had a one to one lesson with a person who
had a new Panasonic GH2 camera. The camera
can shoot HD video and what's amazing is that
it has a feature which acts like a teleconverter, that is,
a camera lens designed to be fitted in front of a standard
lens to increase its effective focal length. A teleconverter
gives you a longer lens length but it also diminishes
the picture quality and it requires that you open
the aperture more. With the GH2, however, in the
extra teleconverter mode, there is no loss of light or
distortion of the image. It's like having a 5 times longer
lens, so the 40 mm becomes over 200 mm.
What will cameras do next?
