Thanks for commenting, Alan! Fundamental thing about using any mirror lens is to become critically aware of how it's going to treat out of focus portions of the scene, particularly highlights, due to the donut hole behavior. . As the focus distance moves out, the OOF effect becomes more critical as the "nearly in focus" zone grows.
Basically, as you reach to longer and longer views with a mirror lens, you need to develop the same sensitivity to the total scene that using an ultra wide always requires or you end up with a pile of distractions that take away from the message of the photograph.
