So are you saying that you get no light loss any more? I would expect light loss as the way most macro lenses work is to incerase the distance of the elements from the sensor - similar to adding extension tubes. This naturally causes light loss so I'd be surprise if a lens maintains the same exposure at infinity and 1:1[/quote]
No. That's not what I'm saying. The last test had nothing to do with light loss at all. I just wanted to see if the communication issue has any effect on exposure. Rainer's experience seem to corroborate it. Mine does not.
