Of course, the focal length of the lens doesn't change, focal length is a physical property of the lens. I think what you meant was that the angle of view of a legacy lens, adapted to a m-4/3 camera, is equivalent to that of a lens of about double the focal length when mounted to a 135-format camera.
It might also benefit the OP to know that he should set his camera to Aperture Priority mode ("A" mode) when using legacy lenses. This will cause the camera to set the shutter speed based upon the light passing through the stopped-down lens aperture and the camera's ISO setting.
As for general use of your new camera, I might also suggest that you don't use the spot metering mode, as you can get wonky exposures if, for instance, the spot happens to fall upon a dark patch in an otherwise bright scene, the camera will grossly over-expose the scene. I prefer to use my G1 in center-weighted metering, with the metering and AF box set to about 1/3 the width of the frame.
Good luck and show us some photos!
