There seems to be an obvious explanation to this that has been missed, which has nothing to do with the alignment, if the lens is being used with TTL metering. The meter will see a *much* larger area than with less extreme wide angles, and may be metering large expanses of sky, which would obviously cause underexposure. I would suggest testing with a hand held meter, especially a spot meter if available, and seeing if the area that was measured is properly exposed.
