This has me curious. Can we use this technology to emulate a variety of lens designs?
Not sure if the situation translates from extreme macro to ordinary photography, Collin. The depth of field is sliver thin, and the lens is reverse mounted.
Take, for instance the old Pentax-A 70-210/4 vs the Takumar-A 70-200. The Tak-A has a much shorter transition from in-focus to out-of-focus. Might one also use stacking with a mirror lens to eliminate the doughnut bokeh?
You'd be able to eliminate the doughnuts that appear inside the extended focus area. They'll remain in the OOF area though.

Perhaps through stacking someone might emulate the unique character of a Petzval or a Protar. They certainly can't be done in a single layer. Will be interesting to see what the future holds. An engineer might use such technology with appropriate (mathematical) filters to predict lens design behavior without ever building it. Like an optical add-in for catia. Collin
