It appears the DS lens usies an apodosation coating, rather than an apodisation element.
Very interesting. However, not for me.

Kind regards, Wim

As far as I know apodization element is neutral-gray tinted lens element. The purpose of this is to smooth edges.
At modern days, the same effect can be achieved by  combining depth-of-field bracketing with multi exposure, as implemented in the Minolta Maxxum 7's. Maybe modern smartphone apps already have it
 
Apodization sounds cool marketing bizz, but actually I use the apodization function in my everyday life - the prpose is to smooth the discrete FFT. Many windows I use . All of them are type op apodization functions.
