Many Pentax digital lenses tend to underexpose by -0.5 to -1EV and particularly digital zooms like to be darker. The FA 50 is just a lens which tends to be just brighter (but not overexpose IMO) and thus you see the difference.
For more info about the relative brightness and darkness of Pentax lenses, you can have a look on my this summary:-
RiceHigh's (Pentax) DSLR and Lens Measurbation Page on Exposure Accuracy and More..
And, the K20D is not really famous for exposure accuracy and consistency, so just the body could introduce more errors than it should be, see my following simple and factual analysis:-
RiceHigh's Pentax Blog: K20D Exposure Inaccuracy and Inconsistency
But since you have already got your new K20D, I think you have to live with it. The only way to compensate is to apply a different suitable +/-EV compensation whenever you change a different lens.
