In the "Rear Window" movie, the main character, played by Jimmy Stewart, is shown holding a nice looking camera with an enormous lens.

What camera and lens is that?

Found this thread (http://http://www.ihagee.org/top01.htm) via Google.
Accoring to them it was a Topica Exakta.

The lens info or questions are at the bottom of the page.
