Another thing to consider is that Panasonic 12-35 is slighfly brighter (by about 1/4~1/3 stop according to Dx0) compared to oly 12-40. Comparing 12-35 to some of the other lenses I have, it does seem to be slightly brighter at same apertures.

I wouldn't trust the DxO transmission measurements to anywhere close to 1/4 a stop. Brandon Dube from Olaf did some analysis with some other forums members here and found their t-stop values for the 25 PRO were off by the better part of a stop.
