As a curiousity,were you looking through the ocular,while making those adjustments?
I was looking through the end you do when you focus the reticle as I have for all of my 14 Leupold rifle scopes.
There are two lenses that move opposing to each other that adjusts the focus and diopter effect.
Sorry for saying these lenses were the objective, a lens (camera) to me consists of objectives which work together to create focusing.
