If the distance between the rear nodal point of a lens and its focal plane is less than 305 mm, the lens is described as having what?

Explanation:
The concept here is how focal length is related to the distance from the lens’s rear nodal point to the focal plane. A shorter distance means the lens has a shorter focal length. Short focal length lenses capture wider scenes and show more of the scene in focus with a broader field of view, compared to longer focal lengths which magnify and compress perspective. Since the distance is less than 305 mm, it fits the short focal length category. Longer distances would indicate longer focal lengths, producing telephoto effects.
