This is interesting, but silly. It&#x27;s hard to imagine a practical use for this other than perhaps wanting to flip between two versions of a photo with one wide open and one sharp across the frame. But you&#x27;ll have different shutters anyway to keep the same exposure.<p>Seems like this was spawned from a moment of inquiry where someone was so preoccupied with whether they could that no one stopped to think about whether they should.
