I can't believe that the sensor reflectivity is a function of the set ISO???

The exposure will be correct only at ISO400 as the development and testing of the TTL-measurement was apparently made at ISO400, only. At ISO settings below 400 the camera will under-expose, at setting above 400 it will over-expose.(*) This problem can probably not be solved by a firmware update as there is no upgradeble TTL-software but some kind of hardware solution. The problem does not exist if you use P-TTL. ---------------------------------------------------------------------- (*) In the meanwhile I could confirm this behaviour. Maybe changing to ISO400 will solve you problem. Hope it helps... Cheers, Heiko
