just to be sure, when you mean you need exposure compensation, is that to get the same camera settings on both, (aperture and shutter) or do you mean that there is a 20 point difference in greyscale value when shooting the same scene but the exposure values are different also?
I am just trying to determine if this is just the difference between one manufacturer and another in the set point they use for ISO. I seem to recall a discussion a while back about this issue and not all manufacturers set to the same point.
to be fair do a set of tests the first at each aperture for each camera, on a grey body (wall, road or what ever) and record / plot shutter speed and grey scale value of the image for each.\
this will tell us a lot about how each camera really meters
