You mean field or angle of view, not perspective. Perspective depends solely upon one's point or position of view, regardless of format and focal length. Also, since the aspect ratio of 35mm is 3:2 and the aspect ratio of 6x7 is 7:6, focal length/field of view comparisons don't really work.

I'm not really sure what the OP is asking.
