I'm still not sure about this. While I agree that on the first image i.e. the sensor
or film the effect will be the same as for the 800mm lens, as the enlargement to a
same sized print is greater for the *istD compared to the 35mm film camera, you are
also enlarging the shake which will then be comparable to the longer lens. After all a
selective enlargement of a negative has the same effect with regards to foreshortening
as fitting a longer lens if the camera position doesn't alter.
Or am I mistaken?
Nick.

Note that as Bill Robb has frequently pointed out, an 800 mm lens on
the *ist D is not the same as a 1200mm lens on a 35mm film camera. It
only shares the field of view. Things like the shake factor and the
forshortening of elements are the same as any 800mm lens on any camera.
