Sticking to the topic of the LENS ...
per the thread title question:
Lenses with larger exit pupils, relative to their focal length, and/or vs. their exit pupil : entrance pupil ratio, exhibit greater 3D-ishness than their counterparts with smaller exit pupils.
The rate of transition from the focal plane ... away from the focal plane, is different. The more rapidly that rate of transition is, the greater the perception of relative depth variance is discernible.
This is not the same thing as shallow dof, but rate of transition. Which to a certain degree can also be generated via pp to adjust the rate of change. Field curvature designs of different lenses can also be a factor that influences the rate of change, in conjunction with focal plane / subject placement. All other pieces of the puzzle contribute, but as it pertains to the lens design, this is what I was able to correlate.
Looking for 3D-ish inducing lenses ... start by looking at their exit pupils size.
This is the summation of my studies on lenses that were stronger producers vs. weak producers over a decade ago.
