Hey Mark you never posted answers to these Q's...

[KirkDarling]

C) All camera formats have the same focal length normal lens is untrue
C) the hyperfocal distance. A lens focused at the hyperfocal distances has depth of field extending from approximately half the hyperfocal distance to infinity, whereas a lens focused at infinity has a depth of field only at infinity.
A) Perspective is affected only by the distance of camera to subject

Oopsie. Kirk is right, as are several of the others. I think what happened was I sent the answers to Ellen, and internally ticked it off as completed. My apologies.
