Glad you're enjoying your 200.  Suggesting something specifically as the
root of your fogging problems is difficult without having access to the
body and tryiny out a number of tests.  However, the 200 has a lot of
potential places where light leaks could occur.  I would recommend renewing
all of the foam light seals on the camera, of which there are quite a few
but at least are reasonably easy to access.

Try http://www.fargo-ent.com/  for a good source of replacement foam.

First place to look is the seal around the lens itself, then carry on back
through the camera.


All the best,
