Oops, I did not know of that Minolta switch...
I'm sorry for that!
But: Why do it complicated when you can do it simple?
That grey-filter acting dome reduces the effective sensibiltiy of the meter in the incident lighting mode. Using a switch on the electric circuit and a more transparent dome gives more sensitivity in that mode.
However, that dome will have a certain opacity anyway in order to be effective. And any photographer working under such conditions should be able to do incident light metering without dome and to re-calculate the result...
