Thanks for the tip, but wont work in this case, since the precomps are not the same dimensions as the master comp, and the precomps also have animated translation in the master comp. 
So i think an updated expression is the only way to go, or doing it manually with keyframes.... my last resort :-)

perhaps linking precomp camera's attributes to the main comp's one.

tell me if it works!
