Re: Is it possible to make an autofocus mirror lens?

Cut out some holes in a cardboard, place it in front of the mirror lens and try i out.

There is possible to avoid doughnut bokeh with the use of off axis desings, with some side effects (much coma). Search for yolo telescope or off axis telescope designs.
