Hi Tanja,I had this(have )problem.If you know what you are doing you can take the viewfinder out of the *istD from inside.It slides out from the bracket that holds it.The holding bracket swings down after being unclipped.Sometimes gunk etc. gets caught behind the viewfinder and wont blow away.However if you do attempt to remove the viewfinder be extra gentle.But it can be done.
