what would happen if you put a four thirds lens on a larger sensor

I know that there is a difference in the register (lens to sensor distance) that makes this impossible, what Im after, is a description of what happens when the small image circle appears on a larger sensor, do you for instance get a large black border on the frame ?

Yes, you would get a circular image with a black background since the image circle would not "cover" the sensor. A short search on google to find some article regarding sensor size vs. image circleproduced this Adobe .pdf form:

thanks Greg
i guess i thought it might clip the frame at the edges of the image
but that wouldnt work so well if the image had a lot of black in it

anyway thanks for the answer
