I think it should be pointed out that any TLR does have parallax
error. Parallax error means you are looking at your subject from a
different _angle_ than your taking lens. If you are taking a picture
of a flat subject parallel to your film, you can build masking
features into your viewfinder, such as Rollei has done, to give you a
pretty exact idea of what you are getting. This is also common
practice in various direct view camera systems, such as Leicas or
Koni-Omegas. In the end, though, if your subject is three dimensional
and the relationship of foreground and background is critical, such
parallax compensation is not accurate enough, because of the angular
difference.
A Rollei TLR is just as prone to parallax error as any other TLR,
whether Mamiya or Gowlandflex.
