This conversion doesn't actually make any technical sense. Yes, you can calculate the field of view, but the depth of field, the angles of sight lines etc. are that of a 35mm lens. For an intuitive way to visualize this: look at a few dolly zooms and think about what you are seeing in terms of geometry.
