zone plate question

I was interested in Guillermo's recent post about the relationship
between number of rings and zone plate image sharpness. I have a
converted Lubitel with 75mm focal length. If I wanted a camera with
MORE distortion (which I understand from Guillermo's post would also be
a faster camera), would I need a camera with a longer or shorter focal
length? Thanks in advance.
