Thanks for the info.
My problem is figuring out what Metz MEANS in that little table they give you when you search for an adapter.
For example for the 40MZ-3i, you get the following -
TTL Flash Control - It says it works with : Camera/Adapter/Flash/Combination.
But then pretty much EVERYTHING else is only only listed as being a feature of the flash.
Such as automatic flash synch (which is ODD on a camera with a leaf shutter...isn't EVERYTHING synched?) or Rear Curtain.
Does this mean the features won't work on my ETRsi?
